Flutter 应用程序更新后崩溃：java.lang.IllegalAccessError，如何避免此问题？
Flutter 应用程序在 Play 商店更新后崩溃
我在 google play 控制台上发生了大量崩溃，并出现这种类型的错误： java.lang.IllegalAccessError
大约 20% 的用户在 Play 商店更新应用程序时发生了此崩溃：

此问题的历史记录 ⌚- >
我在使用生产应用程序时遇到了问题，该应用程序已经在颤振旧版本中工作了一段时间，没有空安全性（之前）。 我已将应用程序迁移到flutter的null安全版本，并添加了android 12兼容性。之后我将其添加到游戏商店的版本中。那是应用程序版本 1.3.0，没有任何大规模的崩溃案例（于 2022 年 2 月 21 日下午 6:21 发布，于 2022 年 3 月 17 日晚上 8:20 停止推出，提到的崩溃案例为零）。 在该版本的应用程序中，我有这种类型的依赖项：
auto_orientation: ^2.2.0
cached_network_image: ^3.2.0
connectivity: ^3.0.6
dio: ^4.0.4
dio_http_cache: ^0.3.0

path_provider: ^2.0.8
firebase_analytics: ^9.0.5
firebase_messaging: ^11.2.5

share: ^2.0.4
shared_preferences: ^2.0.11
shimmer: ^2.0.0
sqflite: ^2.0.1
url_launcher: ^6.0.17
之后，我在应用程序中对设计模式和状态管理进行了一些更改。我的应用程序在调试模式下运行没有任何错误，我已经在几个设备上对其进行了测试。没有任何崩溃，并在 Play 商店推出了我的应用程序，版本名称为 2.0.0，（于 2022 年 3 月 17 日晚上 8:20 发布，于 2022 年 3 月 19 日晚上 9:39 替换，之前提到的崩溃案例有 13700 例）直到今天，开始推出时为 40%，我不认为这是一个大问题，一天后增加到 100%），其中我有这种类型的依赖项：
auto_orientation: ^2.2.0
cached_network_image: ^3.2.0
chewie: ">=1.1.0 <1.1.1"
connectivity_plus: ^2.2.1

scrollable_positioned_list: ^0.2.3
share_plus: ^3.0.5
shared_preferences: ^2.0.13
shimmer: ^2.0.0
url_launcher: ^6.0.20
之后我感到恐慌并停止了发布。我已经将之前的版本发布到生产环境中，版本名称为 1.3.1，因为它没有这种类型的崩溃。 不幸的是，这个版本的应用程序有大量相同的崩溃类型（于2022年3月19日晚上9:39发布，于2022年3月25日下午3:01替换，以100%推出，因为避免了以前的崩溃，但它是无用的）。 某种清理的应用程序存储或重新安装对大多数手机都有帮助。之后我想如果我从应用程序端清理应用程序目录和缓存日期，它就不会崩溃并发布了 2.0.1 版本（应用程序在大多数用户中崩溃），但它并不成功。

History of this trouble ⌚->
I'm having trouble with production app, which has been working for a while in flutter old version without null safety(before).
I have migrate app into null safety version of flutter, and added android 12 compatibility. After that I have added it into release at play store. That was app version 1.3.0 and there wasn't any massive case of crash (released at Feb 21, 2022 6:21 PM Rollout halted on Mar 17, 2022 8:20 PM, zero case of mentioned crash).
In that version of app I had this types of dependencies:
auto_orientation: ^2.2.0
cached_network_image: ^3.2.0
connectivity: ^3.0.6
dio: ^4.0.4
dio_http_cache: ^0.3.0
dotted_line: ^3.1.0
path_provider: ^2.0.8
firebase_analytics: ^9.0.5
firebase_messaging: ^11.2.5
flutter_html: ^2.2.1
google_mobile_ads: ^1.0.1
video_player: ^2.2.15
hive: ^2.0.5
hive_flutter: ^1.1.0
photo_view: ^0.13.0
provider: ^6.0.2
pull_to_refresh: ^2.0.0
scrollable_positioned_list: ^0.2.3
share: ^2.0.4
shared_preferences: ^2.0.11
shimmer: ^2.0.0
sqflite: ^2.0.1
url_launcher: ^6.0.17
After that I made some changes in design pattern and state managment in my app. My app was working without any kind of error in debug mode, I have tested it in couple of devices. There wasn't any crash and rolled out my app at play store with version name 2.0.0, (released at Mar 17, 2022 8:20 PM Replaced on Mar 19, 2022 9:39 PM, 13.7K case of before mentioned crash till today, started rollout at 40% and I haven't thought it was big problem, after one day increased into 100%) in which I had this types of dependencies:
auto_orientation: ^2.2.0
cached_network_image: ^3.2.0
chewie: ">=1.1.0 <1.1.1"
connectivity_plus: ^2.2.1
equatable: ^2.0.3
dio: ^4.0.4
dio_cache_interceptor: ^3.2.6
dio_cache_interceptor_hive_store: ^3.1.1
ferry: ^0.10.4
firebase_analytics: ^9.0.5
firebase_messaging: ^11.2.5
flutter_html: ^2.2.1
provider: ^6.0.2
google_mobile_ads: ^1.0.1
hive: ^2.0.5
path_provider: ^2.0.9
photo_view: ^0.13.0
pull_to_refresh: ^2.0.0
scrollable_positioned_list: ^0.2.3
share_plus: ^3.0.5
shared_preferences: ^2.0.13
shimmer: ^2.0.0
url_launcher: ^6.0.20
After that I had panic and halted that release. And I have released into productuion previous release with version name 1.3.1, because it hasn't this type of crash.
Unfortunatly this version of app had plenty amount of same crash type(released at Mar 19, 2022 9:39 PM Replaced on Mar 25, 2022 3:01 PM, rollout at 100% because avoid previous crash but it was useless).
Some kind of cleaned app storage or reinstalling helped in most of phones. After that I thought if I clean app directories and cache date from app side, it won't crash and released 2.0.1 version(App is getting crash in most of users) but it wasn't succesfull.

This app ha about 25K users, in summary it had 55,347 same crash occurrences and more than 6500 useres impacted with mentioned crash ????.
I'm thankfull for any help, suggestions or advises ????.
What do I expect from app:
- App without this kind of crash in production (if I had this type of crash in debug mode it was way better)
- Any kind of solution to avoid this crash.
- What was wrong with it.
Before I had send issue into play console devs and they mailed me couple of links about java error documentation and about crashes but I haven't found any kind of solution there are and in the entire of internet.

For previous version of app(1.3.0) had same file but hasn't had any similar crash.
And for how I use cached_network_image in my code:
CachedNetworkImage(
imageUrl: widget.post.imageUrl,
width: double.infinity,
fit: BoxFit.cover,
placeholder: (url, ctx) => const BigImageShimmer(),
errorWidget: (context, url, error) => Image.asset(
'assets/images/error_image.png',
fit: BoxFit.cover,
color:
Theme.of(context).textTheme.bodyText1?.color,
),
),

我不确定，但似乎您想在数据库已锁定时访问或写入数据库。也许，您应该有
isOpen方法来检查数据库是否打开。I'm not sure, but it seems like you want to access or write smth to the database when it is already locked. Probably, you should have
isOpenmethod to check whether DB is open.这是我的想法，也许是解决此问题的最快方法：
尝试删除您的 android 文件夹，确保将其保存在安全的地方，以便以后可以访问它。删除当前的 android 文件后，在根目录中运行
flutter create .，这将生成一个新的 android 文件夹。最后，使用上一个文件夹的详细信息编辑新的 android 文件夹。Here's what I think and maybe the quickest way to resolve this:
Try to remove your android folder, make sure you keep it somewhere safe so you can access it later. After removing the current android file, run
flutter create .in your root which would produce a new fresh android folder. Finally, edit your new android folder using the details from the previous one.我首先消除耗时的选项。由于输出的错误日志很可能与
AndroidX相关，请尝试将您的项目重构为 AndroidX。步骤进入Android Studio：
flutter cleanflutter pub cache cleanflutter pub get，注意任何错误如果某些 flutter 包与 AndroidX 不兼容，此解决方案可能无法正常工作。
I eliminate time costly options first. Since the error log outputted is likely to relate
AndroidX, try refactor your project as AndroidX.Step in Android Studio:
flutter cleanflutter pub cache cleanflutter pub get, note about any errorsThis solution may not work well if some of flutter packages are not compatible with AndroidX.

我也面临此错误，我通过将“公共”关键字添加到MainActivity.java来解决它。
Quick solution:
I was facing this error too, I solved it by adding the "public" keyword to MainActivity.java
