我的代码在过去 5 年里没有改变并且工作正常 - 我最近开始看到 StackOverflowError在 Fabric/Firebase Crashlytics 中 - 所有错误均来自 Android 10 设备。
我有一个自定义AsyncTask并使用 task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, data); 激活它
data是我的应用程序中的一个简单对象。
我没有发布我的自定义任务 b/c 我认为该错误是由 android 内部生成的。
此行导致此堆栈跟踪

知道如何处理这个问题吗？
最佳答案
最近的 Android 操作系统优化对后台操作/任务进行了限制，以最佳地利用设备资源(电池、CPU...)。因此，目前有效的功能可能会在 Q 上出现问题。
1)如果AsnycTask在应用程序已经在后台时被触发，它可能会受到操作系统的限制。
2) 如果 AsyncTask 在应用程序处于前台时触发，但处理时间过长，它可能会被操作系统限制/终止。
理想情况下，AsyncTasks 应该用于短操作(最多几秒钟)。Src 。
带有“rejectedExecution”的错误调用堆栈提示我第一种情况，即应用程序处于后台，因此任务被拒绝执行(而不是在其间取消)。 为了让任务在应用程序不在前台时可靠地运行，推荐的方法是使用 Service 类或其扩展版本，例如基于任务需求的IntentService。希望有帮助!
