android - Flutter - Appbundle - Android 应用程序在启动时卡住

Question

我有一个拥有超过 15 万用户的应用程序，直到现在我一直避免使用 appbundle 只是因为我不知道它是如何工作的，但上周我别无选择并发送了一个带有 appbundle 的更新。从那时起，许多用户报告该应用程序启动时死机并出现黑屏(它没有启动画面)。

我查看了 Play 管理中心中的 Android Vitals 并找到了这个

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

backtrace:

我在许多真实设备和许多模拟器 (x86_x64) 上对其进行了测试。不幸的是(或幸运的是)它在所有这些测试中都运行良好。

老实说，我不知道该怎么办。如果有人对正在发生的事情或如何重现这一点有任何暗示，我将不胜感激。

编辑:

问题不在于 appbundle。我尝试使用 --split-per-abi 和两个 apk(“armeabi-v7a”和“arm64-v8a”)，问题仍然存在。

Answer 1

我遇到过这种卡住问题。 Flutter doctor 没有提到任何问题。 building app freeze 之后，我曾经是 flutter master channel 。我将 flutter 切换到稳定版并构建 apk，它工作正常。

命令:

flutter channel stable
