@abelb13/react-native-fcm 中文文档教程
NOTES:
react-native-firebase 引入了新的 firebase 消息传递和远程/本地通知功能。 它与其他 Firebase 功能很好地集成。 我建议新来者检查一下。
请注意,一些高级功能仍在进行中
- handle iOS remote notification when app is not running
- custom iOS notification actions
To existing react-native-fcm users
react-native-firebase
现在可以做 react-native-fcm
可以做的事情,所以构建相同的功能是浪费精力并行的事情。
由于这些天我越来越忙,开始觉得每天维护这个 repo 很有挑战性,而 react-native-firebase
有更大的团队/公司支持它,现有用户可能会考虑迁移到 react -native-firebase。
我创建了示例项目,使用 react-native-firebase 作为迁移参考
react-native-fcm
仍将采用 PR 和错误修复,但可能不再开发新功能。
Versions
- after v16.0.0, Android target SDK has be to >= 26 and build tool has to be >= 26.0.x
- for iOS SDK < 4, use react-native-fcm@6.2.3 (v6.x is still compatible with Firebase SDK v4)
- for RN < 0.40.0, use react-native-fcm@2.5.6
- for RN < 0.33.0, use react-native-fcm@1.1.0
- for RN < 0.30.0, use react-native-fcm@1.0.15
Example
- An example working project is available at: https://github.com/evollu/react-native-fcm/tree/master/Examples/simple-fcm-client
Installation
- Run
npm install react-native-fcm --save
- Link libraries Note: the auto link doesn't work with xcworkspace so CocoaPods user needs to do manual linking
- You many need this package for huawei phone
Configure Firebase Console
FCM config file
在 firebase 控制台中,您可以:
- for Android: download

Config for notification and click_action
in Android
要让 android 响应 click_action
,您需要定义 Activity 并根据特定意图进行过滤。 可以让 MainActivity 来处理操作:
AndroidManifest.xml
:
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize"
+ android:launchMode="singleTop"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
编辑
launchMode="singleTop"
is to reuse MainActivity, you can usesingleTask
orsingleInstance
as well depend on your need. this link explains the behavior well- you if want to handle
click_action
you need to add custom intent-filter, check native android documentation
由于所有 javascript 都在 MainActivity 中运行,因此您 0.30.0 和 react-native-fcm < 1.0.16,将 intent 传递到包中,编辑 MainActivity.java
:
- RN 0.28:
import com.facebook.react.ReactActivity;
+ import android.content.Intent;
public class MainActivity extends ReactActivity {
+ @Override
+ public void onNewIntent (Intent intent) {
+ super.onNewIntent(intent);
+ setIntent(intent);
+ }
注意:验证 react-native 是否正确链接到 MainApplication.java
import android.app.application
...
+import com.evollu.react.fcm.FIRMessagingPackage;
…。
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new VectorIconsPackage(),
+ new FIRMessagingPackage(),
new RNDeviceInfo(),
);
}
- RN <= 0.27:
import com.facebook.react.ReactActivity;
+ import android.content.Intent;
public class MainActivity extends ReactActivity {
+ @Override
+ protected void onNewIntent (Intent intent) {
+ super.onNewIntent(intent);
+ setIntent(intent);
+ }
注意:
@Override
is added to update intent on notification click
IOS Configuration
Pod approach:
确保你有 Cocoapods 版本 > 1.0
配置项目:(
cd ios && pod init
如果有语法错误,打开YOURApp.xcodeproj/project.pbxproj
并修复它们。)
编辑新创建的Podfile
:
# Pods for YOURAPP
+ pod 'Firebase/Messaging'
安装Firebase/Messaging
pod:
pod install
注意:您不需要启用 use_frameworks!
。 如果您必须拥有 use_frameworks!
,请确保您没有 inherit! :搜索路径
分支中有一个工作
Non Cocoapod approach
- Follow the instruction on Integrate without CocoaPods.
- Import libraries, add Capabilities (background running and push notification), upload APNS and etc etc etc…
- Put frameworks under
ios/Frameworks
folder, and drag those files into your xcode solution -> Frameworks - Put
firebase.h
andmodule.modulemap
underios/Frameworks
folder, no need to drag into solution - Modify your project's
User Header Search Paths
and add$(PROJECT_DIR)/Frameworks
NOTE: There is a working example inno-pod

- Background Modes > Remote notifications.
FirebaseAppDelegateProxyEnabled
示例(默认)以便 Firebase 挂钩推送通知注册事件。 如果关闭此标志,您将自行管理 APNS 令牌并链接到 Firebase 令牌。
Setup Local Notifications
注意:本地通知对 FCM 库没有任何依赖性,但您仍然需要包含 Firebase 才能编译。 如果有足够的需求单独使用这个功能,我会将它分离到另一个 repo

Usage
Build custom push notification for Android
Firebase android 错过了 android 通知的重要功能,如 group
、priority
等。作为解决方法,您可以发送数据消息(根本没有 notification
有效负载),此 repo 将为您构建本地通知。 如果您在负载中传递 custom_notification
,repo 会将内容视为本地通知配置并立即显示。
注意:通过使用此解决方法,您将不得不为 iOS 和 Android 设备发送不同类型的有效负载,因为 iOS 不支持 custom_notification
警告:custom_notification
不能与notification
属性一起使用。 使用 data
ALONE
发送到 FCM 服务器
{
"to":"FCM_TOKEN",
"data": {
"type":"MEASURE_CHANGE",
"custom_notification": {
"body": "test body",
"title": "test title",
"color":"#00ACD4",
"priority":"high",
"icon":"ic_notif",
"group": "GROUP",
"id": "id",
"show_in_foreground": true
}
}
}
的负载示例: 通过 firebase 控制台发送的负载示例:
查看下面的本地通知指南以了解配置。
重要:使用admin.messaging
API 时,您需要JSON.stringify
custom_notification
值:
let tokens = [...];
let payload = {
data: {
custom_notification: JSON.stringify({
body: 'Message body',
title: 'Message title'
...
})
}
};
let options = { priority: "high" };
admin
.messaging()
.sendToDevice(tokens, payload, options);
Behaviour when sending notification
and data
payload through GCM
当用户单击通知以启动 应用程序,您可以通过调用
FCM.getInitialNotification
获取该通知。 (注意:重新加载 javascript 或从后台恢复不会更改值)当应用程序在后台运行时(棘手的,我强烈建议您自己尝试一下)
IOS 将收到来自
FCMNotificationReceived
事件的通知- if you pass
content_available
flag true, you will receive one when app is in background and another one when user resume the app. more info - if you just pass
notification
, you will only receive one when user resume the app. - you will not see banner if
notification->body
is not defined.
- if you pass
Android 将从
FCMNotificationReceived
事件接收通知,- if you pass
notification
payload, it will receive data when user click on notification - if you pass
data
payload only, it will receive data when in background
例如 fcm 有效载荷看起来像:
- if you pass
{
"to":"some_device_token",
"content_available": true,
"notification": {
"title": "hello",
"body": "yo",
"click_action": "fcm.ACTION.HELLO"
},
"data": {
"extra":"juice"
}
}
```
and event callback will receive as:
- Android
```json
{
"fcm": {"action": "fcm.ACTION.HELLO"},
"opened_from_tray": 1,
"extra": "juice"
}
```
- iOS
```json
{
"apns": {"action_category": "fcm.ACTION.HELLO"},
"opened_from_tray": 1,
"extra": "juice"
}
```
- When app is running in foreground
- IOS will receive notification and android **won't** (better not to do anything in foreground for hybrid and send a separate data message.)
NOTE: it is recommended not to rely on `data` payload for click_action as it can be overwritten (check [this](http://stackoverflow.com/questions/33738848/handle-multiple-notifications-with-gcm)).
### Quick notes about upstream messages
If your app server implements the [XMPP Connection Server](https://firebase.google.com/docs/cloud-messaging/server#implementing-the-xmpp-connection-server-protocol) protocol, it can receive upstream messages from a user's device to the cloud. To initiate an upstream message, call the `FCM.send()` method with your Firebase `Sender ID` and a `Data Object` as parameters as follows:
javascript FCM.send('984XXXXXXXXX', { 我的自定义数据1:“我的自定义字段值1”, 我的自定义数据2:“我的自定义字段值2” });
The `Data Object` is message data comprising as many key-value pairs of the message's payload as are needed (ensure that the value of each pair in the data object is a `string`). Your `Sender ID` is a unique numerical value generated when you created your Firebase project, it is available in the `Cloud Messaging` tab of the Firebase console `Settings` pane. The sender ID is used to identify each app server that can send messages to the client app.
### Sending remote notifications with category on iOS
If you want to send notification which will have actions as you defined in app it's important to correctly set it's `category` (`click_action`) property. It's also good to set `"content-available" : 1` so app will gets enough time to handle actions in background.
So the fcm payload should look like this:
javascript { "to": "somedevicetoken", “内容可用”:是的, “通知”: { "title": "报警", "subtitle": "第一声警报", “身体”:“第一警报”, "clickaction": "com.myapp.MyCategory" // 您使用 FCM.setNotificationCategories 定义的通知类别的 id }, “数据”: { “额外”:“果汁” } }
## Q & A
#### Why do you build another local notification
Yes there are `react-native-push-notification` and `react-native-system-notification` which are great libraries. However
- We want a unified local notification library but people are reporting using react-native-push-notification with this repo has compatibility issue as `react-native-push-notification` also sets up GCM.
- We want to have local notification to have similar syntax as remote notification payload.
- The PushNotificationIOS by react native team is still missing features that recurring, so we are adding it here
#### My Android build is failing
Try update your SDK and google play service.
If you are having multiple plugins requiring different version of play-service sdk, skip conflicting group. The example project shows for how to colive with react-native-maps
compile(project(':react-native-maps')) {
exclude group: 'com.google.android.gms', module: 'play-services-base'
}
#### My App throws FCM function undefined error
There seems to be link issue with rnpm. Make sure that there is `new FIRMessagingPackage(),` in your `Application.java` file
#### I can't get notification in iOS emulator
Remote notification can't reach iOS emulator since it can't fetch APNS token. Use real device.
#### I'm not getting notfication when app is in background
1. Make sure you've uploaded APNS certificates to Firebase and test with Firebase's native example to make sure certs are correct
2. Try simple payload first, sometimes notification doesn't show up because of empty body, wrong sound name etc.
#### App running in background doesn't trigger `FCMNotificationReceived` when receiving hybrid notification [Android]
These is [an issue opened for that](https://github.com/google/gcm/issues/63). Behavior is not consistent between 2 platforms
#### Android notification is showing a white icon
Since Lollipop, the push notification icon is required to be all white, otherwise it will be a white circle.
#### iOS not receiving notification when the app running in the background
- Try adding Background Modes permission in Xcode->Click on project file->Capabilities tab->Background Modes->Remote Notifications
#### I am using Proguard
You need to add this to your `android/app/proguard-rules.pro`:
Google Play Services
-保持类 com.google.android.gms.** { ; } -dontwarn com.google.android.gms.*
#### I'm getting `com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzqf;`
It is most likely that you are using other react-native-modules that requires conflicting google play service
search for `compile "com.google.android.gms` in android and see who specifies specific version. Resolve conflict by loosing their version or specify a version resolve in gradle.
Check this article https://medium.com/@suchydan/how-to-solve-google-play-services-version-collision-in-gradle-dependencies-ef086ae5c75f#.9l0u84y9t
#### How do I tell if user clicks the notification banner?
Check open from tray flag in notification. It will be either 0 or 1 for iOS and undefined or 1 for android. I decide for iOS based on [this](http://stackoverflow.com/questions/20569201/remote-notification-method-called-twice), and for android I set it if notification is triggered by intent change.
#### Android notification doesn't vibrate/show head-up display etc
All available features are [here](https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support). FCM may add more support in the future but there is no timeline.
In the mean time, you can pass "custom_notification" in a data message. This repo will show a local notification for you so you can set priority etc
#### How do I do xxx with FCM?
check out [official docs and see if they support](https://firebase.google.com/docs/cloud-messaging/concept-options)
#### I want to add advanced feature that FCM doesn't support for remote notification
You can either wait for FCM to develop it or you have to write native code to create notifications.
- for iOS, you can do it in `didReceiveRemoteNotification` in `appDelegate.m`
- for android, you can do it by implementing a service similar to "com.evollu.react.fcm.MessagingService"
Or if you have a good way to wake up react native javascript thread please let me know, although I'm worring waking up the whole application is too expensive.
#### What about new notifications in iOS 10
Congratulations, now you have 5 notification handler to register!
in sum
- `willPresentNotification` is introduced in iOS 10 and will only be called when local/remote notification will show up. This allows you to run some code **before** notification shows up. You can also decide how to show the notification.
- `didReceiveNotificationResponse` is introduced in iOS 10 and provides user's response together with local/remote notification. It could be swipe, text input etc.
- `didReceiveLocalNotification` is for iOS 9 and below. Triggered when user clicks local notification. replaced by `didReceiveNotificationResponse`
- `didReceiveRemoteNotification` is for iOS 9 and below. Triggered when remote notification received.
- `didReceiveRemoteNotification:fetchCompletionHandler` is for both iOS 9 and 10. it gets triggered 2 times for each remote notification. 1st time when notification is received. 2nd time when notification is clicked. in iOS 9, it serves us the purpose of both `willPresentNotification` and `didReceiveNotificationResponse` but for remote notification only. in iOS 10, you don't need it in most of the case unless you need to do background fetching
Great, how do I configure for FCM?
It is up to you! FCM is just a bridging library that passes notification into javascript world. You can define your own NSDictionary and pass it into notification.
#### I want to show notification when app is in foreground
Use `show_in_foreground` attribute to tell app to show banner even if the app is in foreground.
NOTE: this flag doesn't work for Android push notification, use `custom_notification` to achieve this.
NOTE: foreground notification is not available on iOS 9 and below
#### Do I need to handle APNS token registration?
No. Method swizzling in Firebase Cloud Messaging handles this unless you turn that off. Then you are on your own to implement the handling. Check this link https://firebase.google.com/docs/cloud-messaging/ios/client
#### I want to add actions in iOS notification
Check this https://github.com/evollu/react-native-fcm/issues/325
#### React/RCTBridgeModule.h not found
This is mostly caused by React Native upgrade. Here is a fix http://stackoverflow.com/questions/41477241/react-native-xcode-upgrade-and-now-rctconvert-h-not-found
#### Some features are missing
Issues and pull requests are welcome. Let's make this thing better!
#### Credits
Local notification implementation is inspired by react-native-push-notification by zo0r
#### I get the notifications in the logs, but the native prompt does not show up
Did you remember to ask the user permissions? ;)
js 等待 FCM.requestPermissions({ badge: false, sound: true, alert: true })
## Sending remote notification
How to send a push notification from your server? You should `POST` to this endpoint:
https://fcm.googleapis.com/fcm/send
You need to set the headers of `Content-Type` to `application/json` and `Authorization` to `key=******` where you replace `******` with the "Legacy server key" from here the Firebase dashbaord. Get this information by first going to:
1. https://console.firebase.google.com/
2. Click on "Gear" icon and click "Project Settingss". Screenshot: https://screenshotscdn.firefoxusercontent.com/images/35b93de8-44e1-49af-89d7-140b74c267c7.png
3. Click on "Cloud Message" tab and find "Legacy server key" here. Screenshot: https://screenshotscdn.firefoxusercontent.com/images/c52ec383-783d-47d3-a1e6-75249fb6f3fb.png
The body should be json like this:
{ “到”:“FCM设备令牌去这里”, “数据”: { “自定义通知”:{ “身体”:“测试机构”, "title": "测试标题", “颜色”:“#00ACD4”, “优先级”:“高”, "icon":"ic启动器", “组”:“组”, “声音”:“默认”, “编号”:“编号”, “在前景中显示”:true } } }
Example:
fetch('https://fcm.googleapis.com/fcm/send', { 方法:'POST', 标题:{ '内容类型':'应用程序/ json' '授权':'key = EFefklefwef9efwefkejfwf' }, 正文:JSON.stringify({ "to":"kajfsdf:efawefwefsdfdsf-asfawefwefwfasdfsdfasd-asdfasdfsd9Aasdfsdfasdf", “数据”: { “自定义通知”:{ “身体”:“测试机构”, "title": "测试标题", “颜色”:“#00ACD4”, “优先级”:“高”, "icon":"icnotif", “组”:“组”, “声音”:“默认”, “编号”:“编号”, “在前景中显示”:true } } }) }) ```
NOTES:
react-native-firebase has introduced new firebase messaging and remote/local notification features. It has good integration with other firebase features. I would recommend new comers to check that.
Note that there are some advanced features still in progress
- handle iOS remote notification when app is not running
- custom iOS notification actions
To existing react-native-fcm users
react-native-firebase
now can do what react-native-fcm
can so it is a waste of effort to build the same thing in parallel.
Since I'm getting busier these days and start feeling challenging to maintain this repo every day while react-native-firebase
has a larger team/company backing it, existing users may consider migrating to react-native-firebase
.
I've created an example project using react-native-firebase as a migration reference
react-native-fcm
will still take PRs and bug fixes, but possibly no new feature developement any more.

Config for notification and click_action
in Android
To allow android to respond to click_action
, you need to define Activities and filter on specific intent. Since all javascript is running in MainActivity, you can have MainActivity to handle actions:
Edit AndroidManifest.xml
:
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize"
+ android:launchMode="singleTop"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Notes:
launchMode="singleTop"
is to reuse MainActivity, you can usesingleTask
orsingleInstance
as well depend on your need. this link explains the behavior well- you if want to handle
click_action
you need to add custom intent-filter, check native android documentation
If you are using RN < 0.30.0 and react-native-fcm < 1.0.16, pass intent into package, edit MainActivity.java
:
- RN 0.28:
import com.facebook.react.ReactActivity;
+ import android.content.Intent;
public class MainActivity extends ReactActivity {
+ @Override
+ public void onNewIntent (Intent intent) {
+ super.onNewIntent(intent);
+ setIntent(intent);
+ }
NOTE: Verify that react-native links correctly in MainApplication.java
import android.app.application
...
+import com.evollu.react.fcm.FIRMessagingPackage;
….
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage(),
new VectorIconsPackage(),
+ new FIRMessagingPackage(),
new RNDeviceInfo(),
);
}
- RN <= 0.27:
import com.facebook.react.ReactActivity;
+ import android.content.Intent;
public class MainActivity extends ReactActivity {
+ @Override
+ protected void onNewIntent (Intent intent) {
+ super.onNewIntent(intent);
+ setIntent(intent);
+ }
Notes:
@Override
is added to update intent on notification click
IOS Configuration
Pod approach:
Make sure you have Cocoapods version > 1.0
Configure the project:
cd ios && pod init
(In case of syntax errors, open YOURApp.xcodeproj/project.pbxproj
and fix them.)
Edit the newly created Podfile
:
# Pods for YOURAPP
+ pod 'Firebase/Messaging'
Install the Firebase/Messaging
pod:
pod install
NOTE: you don't need to enable use_frameworks!
. if you have to have use_frameworks!
make sure you don't have inherit! :search_paths
NOTE: there is a working example in master
branch
Non Cocoapod approach
- Follow the instruction on Integrate without CocoaPods.
- Import libraries, add Capabilities (background running and push notification), upload APNS and etc etc etc…
- Put frameworks under
ios/Frameworks
folder, and drag those files into your xcode solution -> Frameworks - Put
firebase.h
andmodule.modulemap
underios/Frameworks
folder, no need to drag into solution - Modify your project's
User Header Search Paths
and add$(PROJECT_DIR)/Frameworks
NOTE: There is a working example inno-pod
branch
Shared steps
Edit AppDelegate.h
:
+ @import UserNotifications;
+
+ @interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>

+ {
+ [RNFIRMessaging didReceiveNotificationResponse:response withCompletionHandler:completionHandler];
+ }
+ #endif
+
+ //You can skip this method if you don't want to use local notification
+ -(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {

+
+ - (void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
+ [RNFIRMessaging didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
+ }
Add Capabilities
- Select your project Capabilities and enable:
- Push Notifications
- Background Modes > Remote notifications.
FirebaseAppDelegateProxyEnabled
This instruction assumes that you have FirebaseAppDelegateProxyEnabled=YES (default) so that Firebase will hook on push notification registration events. If you turn this flag off, you will be on your own to manage APNS tokens and link with Firebase token.
Setup Local Notifications
NOTE: local notification does NOT have any dependency on FCM library but you still need to include Firebase to compile. If there are enough demand to use this functionality alone, I will separate it out into another repo
IOS
No change required
Android
Edit AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
+ <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
+ <uses-permission android:name="android.permission.VIBRATE" />

+ <action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
+ <category android:name="android.intent.category.DEFAULT" />
+ </intent-filter>
+ </receiver>
</application>
NOTE: com.evollu.react.fcm.FIRLocalMessagingPublisher
is required for presenting local notifications. com.evollu.react.fcm.FIRSystemBootEventReceiver
is required only if you need to schedule future or recurring local notifications
Usage
Build custom push notification for Android
Firebase android misses important feature of android notification like group
, priority
and etc. As a work around you can send data message (no notification
payload at all) and this repo will build a local notification for you. If you pass custom_notification
in the payload, the repo will treat the content as a local notification config and shows immediately.
NOTE: By using this work around, you will have to send different types of payload for iOS and Android devices because custom_notification isn't supported on iOS
WARNING: custom_notification
cannot be used together with notification
attribute. use data
ALONE
Example of payload that is sent to FCM server:
{
"to":"FCM_TOKEN",
"data": {
"type":"MEASURE_CHANGE",
"custom_notification": {
"body": "test body",
"title": "test title",
"color":"#00ACD4",
"priority":"high",
"icon":"ic_notif",
"group": "GROUP",
"id": "id",
"show_in_foreground": true
}
}
}
Example of payload that is sent through firebase console:
Check local notification guide below for configuration.
IMPORTANT: When using the admin.messaging
API, you need to JSON.stringify
the custom_notification
value:
let tokens = [...];
let payload = {
data: {
custom_notification: JSON.stringify({
body: 'Message body',
title: 'Message title'
...
})
}
};
let options = { priority: "high" };
admin
.messaging()
.sendToDevice(tokens, payload, options);
Behaviour when sending notification
and data
payload through GCM
When user clicks notification to launch the application, you can get that notification by calling
FCM.getInitialNotification
. (NOTE: reloading javascript or resuming from background won't change the value)When app is running in background (the tricky one, I strongly suggest you try it out yourself)
IOS will receive notificaton from
FCMNotificationReceived
event- if you pass
content_available
flag true, you will receive one when app is in background and another one when user resume the app. more info - if you just pass
notification
, you will only receive one when user resume the app. - you will not see banner if
notification->body
is not defined.
- if you pass
Android will receive notificaton from
FCMNotificationReceived
event- if you pass
notification
payload, it will receive data when user click on notification - if you pass
data
payload only, it will receive data when in background
e.g. fcm payload looks like:
- if you pass
{
"to":"some_device_token",
"content_available": true,
"notification": {
"title": "hello",
"body": "yo",
"click_action": "fcm.ACTION.HELLO"
},
"data": {
"extra":"juice"
}
}
```
and event callback will receive as:
- Android
```json
{
"fcm": {"action": "fcm.ACTION.HELLO"},
"opened_from_tray": 1,
"extra": "juice"
}
```
- iOS
```json
{
"apns": {"action_category": "fcm.ACTION.HELLO"},
"opened_from_tray": 1,
"extra": "juice"
}
```
- When app is running in foreground
- IOS will receive notification and android **won't** (better not to do anything in foreground for hybrid and send a separate data message.)
NOTE: it is recommended not to rely on `data` payload for click_action as it can be overwritten (check [this](http://stackoverflow.com/questions/33738848/handle-multiple-notifications-with-gcm)).
### Quick notes about upstream messages
If your app server implements the [XMPP Connection Server](https://firebase.google.com/docs/cloud-messaging/server#implementing-the-xmpp-connection-server-protocol) protocol, it can receive upstream messages from a user's device to the cloud. To initiate an upstream message, call the `FCM.send()` method with your Firebase `Sender ID` and a `Data Object` as parameters as follows:
javascript FCM.send('984XXXXXXXXX', { mycustomdata1: 'mycustomfieldvalue1', mycustomdata2: 'mycustomfieldvalue2' });
The `Data Object` is message data comprising as many key-value pairs of the message's payload as are needed (ensure that the value of each pair in the data object is a `string`). Your `Sender ID` is a unique numerical value generated when you created your Firebase project, it is available in the `Cloud Messaging` tab of the Firebase console `Settings` pane. The sender ID is used to identify each app server that can send messages to the client app.
### Sending remote notifications with category on iOS
If you want to send notification which will have actions as you defined in app it's important to correctly set it's `category` (`click_action`) property. It's also good to set `"content-available" : 1` so app will gets enough time to handle actions in background.
So the fcm payload should look like this:
javascript { "to": "somedevicetoken", "contentavailable": true, "notification": { "title": "Alarm", "subtitle": "First Alarm", "body": "First Alarm", "clickaction": "com.myapp.MyCategory" // The id of notification category which you defined with FCM.setNotificationCategories }, "data": { "extra": "juice" } }
## Q & A
#### Why do you build another local notification
Yes there are `react-native-push-notification` and `react-native-system-notification` which are great libraries. However
- We want a unified local notification library but people are reporting using react-native-push-notification with this repo has compatibility issue as `react-native-push-notification` also sets up GCM.
- We want to have local notification to have similar syntax as remote notification payload.
- The PushNotificationIOS by react native team is still missing features that recurring, so we are adding it here
#### My Android build is failing
Try update your SDK and google play service.
If you are having multiple plugins requiring different version of play-service sdk, skip conflicting group. The example project shows for how to colive with react-native-maps
compile(project(':react-native-maps')) {
exclude group: 'com.google.android.gms', module: 'play-services-base'
}
#### My App throws FCM function undefined error
There seems to be link issue with rnpm. Make sure that there is `new FIRMessagingPackage(),` in your `Application.java` file
#### I can't get notification in iOS emulator
Remote notification can't reach iOS emulator since it can't fetch APNS token. Use real device.
#### I'm not getting notfication when app is in background
1. Make sure you've uploaded APNS certificates to Firebase and test with Firebase's native example to make sure certs are correct
2. Try simple payload first, sometimes notification doesn't show up because of empty body, wrong sound name etc.
#### App running in background doesn't trigger `FCMNotificationReceived` when receiving hybrid notification [Android]
These is [an issue opened for that](https://github.com/google/gcm/issues/63). Behavior is not consistent between 2 platforms
#### Android notification is showing a white icon
Since Lollipop, the push notification icon is required to be all white, otherwise it will be a white circle.
#### iOS not receiving notification when the app running in the background
- Try adding Background Modes permission in Xcode->Click on project file->Capabilities tab->Background Modes->Remote Notifications
#### I am using Proguard
You need to add this to your `android/app/proguard-rules.pro`:
Google Play Services
-keep class com.google.android.gms.** { ; } -dontwarn com.google.android.gms.*
#### I'm getting `com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzqf;`
It is most likely that you are using other react-native-modules that requires conflicting google play service
search for `compile "com.google.android.gms` in android and see who specifies specific version. Resolve conflict by loosing their version or specify a version resolve in gradle.
Check this article https://medium.com/@suchydan/how-to-solve-google-play-services-version-collision-in-gradle-dependencies-ef086ae5c75f#.9l0u84y9t
#### How do I tell if user clicks the notification banner?
Check open from tray flag in notification. It will be either 0 or 1 for iOS and undefined or 1 for android. I decide for iOS based on [this](http://stackoverflow.com/questions/20569201/remote-notification-method-called-twice), and for android I set it if notification is triggered by intent change.
#### Android notification doesn't vibrate/show head-up display etc
All available features are [here](https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support). FCM may add more support in the future but there is no timeline.
In the mean time, you can pass "custom_notification" in a data message. This repo will show a local notification for you so you can set priority etc
#### How do I do xxx with FCM?
check out [official docs and see if they support](https://firebase.google.com/docs/cloud-messaging/concept-options)
#### I want to add advanced feature that FCM doesn't support for remote notification
You can either wait for FCM to develop it or you have to write native code to create notifications.
- for iOS, you can do it in `didReceiveRemoteNotification` in `appDelegate.m`
- for android, you can do it by implementing a service similar to "com.evollu.react.fcm.MessagingService"
Or if you have a good way to wake up react native javascript thread please let me know, although I'm worring waking up the whole application is too expensive.
#### What about new notifications in iOS 10
Congratulations, now you have 5 notification handler to register!
in sum
- `willPresentNotification` is introduced in iOS 10 and will only be called when local/remote notification will show up. This allows you to run some code **before** notification shows up. You can also decide how to show the notification.
- `didReceiveNotificationResponse` is introduced in iOS 10 and provides user's response together with local/remote notification. It could be swipe, text input etc.
- `didReceiveLocalNotification` is for iOS 9 and below. Triggered when user clicks local notification. replaced by `didReceiveNotificationResponse`
- `didReceiveRemoteNotification` is for iOS 9 and below. Triggered when remote notification received.
- `didReceiveRemoteNotification:fetchCompletionHandler` is for both iOS 9 and 10. it gets triggered 2 times for each remote notification. 1st time when notification is received. 2nd time when notification is clicked. in iOS 9, it serves us the purpose of both `willPresentNotification` and `didReceiveNotificationResponse` but for remote notification only. in iOS 10, you don't need it in most of the case unless you need to do background fetching
Great, how do I configure for FCM?
It is up to you! FCM is just a bridging library that passes notification into javascript world. You can define your own NSDictionary and pass it into notification.
#### I want to show notification when app is in foreground
Use `show_in_foreground` attribute to tell app to show banner even if the app is in foreground.
NOTE: this flag doesn't work for Android push notification, use `custom_notification` to achieve this.
NOTE: foreground notification is not available on iOS 9 and below
#### Do I need to handle APNS token registration?
No. Method swizzling in Firebase Cloud Messaging handles this unless you turn that off. Then you are on your own to implement the handling. Check this link https://firebase.google.com/docs/cloud-messaging/ios/client
#### I want to add actions in iOS notification
Check this https://github.com/evollu/react-native-fcm/issues/325
#### React/RCTBridgeModule.h not found
This is mostly caused by React Native upgrade. Here is a fix http://stackoverflow.com/questions/41477241/react-native-xcode-upgrade-and-now-rctconvert-h-not-found
#### Some features are missing
Issues and pull requests are welcome. Let's make this thing better!
#### Credits
Local notification implementation is inspired by react-native-push-notification by zo0r
#### I get the notifications in the logs, but the native prompt does not show up
Did you remember to ask the user permissions? ;)
js await FCM.requestPermissions({ badge: false, sound: true, alert: true })
## Sending remote notification
How to send a push notification from your server? You should `POST` to this endpoint:
https://fcm.googleapis.com/fcm/send
You need to set the headers of `Content-Type` to `application/json` and `Authorization` to `key=******` where you replace `******` with the "Legacy server key" from here the Firebase dashbaord. Get this information by first going to:
1. https://console.firebase.google.com/
2. Click on "Gear" icon and click "Project Settingss". Screenshot: https://screenshotscdn.firefoxusercontent.com/images/35b93de8-44e1-49af-89d7-140b74c267c7.png
3. Click on "Cloud Message" tab and find "Legacy server key" here. Screenshot: https://screenshotscdn.firefoxusercontent.com/images/c52ec383-783d-47d3-a1e6-75249fb6f3fb.png
The body should be json like this:
{ "to":"FCMDEVICETOKENGOESHERE", "data": { "customnotification": { "body": "test body", "title": "test title", "color":"#00ACD4", "priority":"high", "icon":"iclauncher", "group": "GROUP", "sound": "default", "id": "id", "showinforeground": true } } }
Example:
fetch('https://fcm.googleapis.com/fcm/send', { method: 'POST', headers: { 'Content-Type': 'application/json' 'Authorization': 'key=EFefklefwef9efwefkejfwf' }, body: JSON.stringify({ "to":"kajfsdf:efawefwefsdfdsf-asfawefwefwfasdfsdfasd-asdfasdfsd9Aasdfsdfasdf", "data": { "customnotification": { "body": "test body", "title": "test title", "color":"#00ACD4", "priority":"high", "icon":"icnotif", "group": "GROUP", "sound": "default", "id": "id", "showinforeground": true } } }) }) ```
