问题原因

Unity应用(target SDK 34)上线到GooglePlay，有用户反馈fold5设备上（Android14系统）疯狂闪退，经测试，在小米手机Android14系统的版本复现成功了，奇怪的是apk直接安装没问题，而打包成aab就是疯狂闪退。

Unity版本Unity2020.3.18f1c1。

老办法，logcat抓包，看看闪退日志。

日志有一行引起了我的注意，也就是在闪退前的报错：

No pending exception expected: java.lang.SecurityException: com.xxx.xxx: One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified when a receiver isn't being registered exclusively for system broadcasts

既然有错误，就好解决了，现在问ChatGPT没用的，因为ChatGPT经常会瞎编，所以上谷歌搜索下，立马就搜到了。 android - One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified when a receiver isn't being registered exclusively for system broadcasts - Stack Overflow

As discussed at Google I/O 2023, registering receivers with intention using the RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED flag was introduced as part of Android 13 and is now a requirement for apps running on Android 14 or higher (U+).

If you do not implement this, the system will throw a security exception.

To allow the broadcast receiver to receive broadcasts from other apps, register the receiver using the following code:
context.registerReceiver(broadcastReceiver, intentFilter, RECEIVER_EXPORTED);
To register a broadcast receiver that does not receive broadcasts from other apps, including system apps, register the receiver using the following code:
context.registerReceiver(broadcastReceiver, intentFilter, RECEIVER_NOT_EXPORTED);
Note: That call will need minSdkVersion to be 26 (Android 8) al least

翻译过来就是，Goole I/O 2023讨论的，使用RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED标志注册接收者是Android 13的一部分，现在是运行在Android 14或更高版本(U+)上的应用程序的要求。也就是Android14必须增加该标志。

以前使用registerReceiver不需要设置RECEIVER_EXPORTED / RECEIVER_NOT_EXPORTED这个Flag，现在Android14开始需要设置了，所以抛异常，闪退了。

解决思路

问题找到了，也分析好了，但是因为这是Unity工程直接打包出来的aab，像是一个黑箱，而问题就是Unity打包出来写的registerReceiver没有按照Android14的要求传进去Flag，这个我们可以通过日志确定，可以看到堆栈日志显示com.unity3d.player.PlayAssetDeliveryUnityWrapper.registerDownloadStatusListener这个类注册的Receiver，而这个是Unity的类，无法修改。
