读取Wifi/3G状态异常
您好，我有以下读取网络/Wifi 状态的代码：
public String getMacAddress() {
WifiManager wm = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
return wm.getConnectionInfo().getMacAddress();
}
这会抛出
Caused by: java.lang.SecurityException: WifiService: Neither user 10032 nor current process has android.permission.ACCESS_WIFI_STATE
并
public boolean is3G() {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
return !(connectivityManager.getNetworkInfo(
ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED || connectivityManager
.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED);
}
会抛出
Caused by: java.lang.SecurityException: ConnectivityService: Neither user 10032 nor current process has android.permission.ACCESS_NETWORK_STATE.
在有人告诉我有关权限的信息之前，这是我的清单（相关部分）：
<manifest>
<!-- usual tags for activitys... etc.. -->
<uses-permission android:name="android.permission.WRITE_OWNER_DATA" />
<uses-permission android:name="android.permission.READ_OWNER_DATA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<user-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<user-permission android:name="android.permission.ACCESS_WIFI_STATE" />
</manifest>
Hi I have the following code that reads Network/Wifi state:
public String getMacAddress() {
WifiManager wm = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
return wm.getConnectionInfo().getMacAddress();
}
This throws
Caused by: java.lang.SecurityException: WifiService: Neither user 10032 nor current process has android.permission.ACCESS_WIFI_STATE
And
public boolean is3G() {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
return !(connectivityManager.getNetworkInfo(
ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED || connectivityManager
.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED);
}
This throws
Caused by: java.lang.SecurityException: ConnectivityService: Neither user 10032 nor current process has android.permission.ACCESS_NETWORK_STATE.
Before someone tell me about the permissions, that is my Manifest (the relevant part):
<manifest>
<!-- usual tags for activitys... etc.. -->
<uses-permission android:name="android.permission.WRITE_OWNER_DATA" />
<uses-permission android:name="android.permission.READ_OWNER_DATA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<user-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<user-permission android:name="android.permission.ACCESS_WIFI_STATE" />
</manifest>

您拼错了最新 2 个权限：
useR-permission 而不是 useS-permission
You've mispelled the latest 2 permissions:
useR-permission instead of useS-permission
您的清单权限错误。
您拥有用户权限而不是使用权限
Your manifest permissions are wrong.
you have user-permission instead of uses-permission
