请找到下面的堆栈跟踪。 ANR 有时会在屏幕上出现，这是我在 logcats 中得到的堆栈跟踪。在此之前我们正在做一些位图处理，所以不确定它是否与内存有关。

查看 ANR 的描述https://developer.android.com/topic/performance/vitals/anr
我猜你是在主线程（在这个调度程序中）而不是在后台做这个提到的位图处理？但是没有你的代码很难说。
您也可以尝试使用 StrictMode，可能正在寻找 slowCall - https://developer.android.com/reference/android/os/StrictMode#noteSlowCall(java.lang.String)
识别代码中应用程序主线程忙碌超过 5 秒的地方。在您的应用中寻找可疑用例并尝试重现 ANR。 由于您正在运行的服务，可能会发生这种情况。尝试在其他线程或线程句柄上运行此任务。您可以使用以下代码
HandlerThread handlerThread = new HandlerThread("MyHandlerThread");
handlerThread.start();
// Now get the Looper from the HandlerThread
// NOTE: This call will block until the HandlerThread gets control and
initializes its Looper
Looper looper = handlerThread.getLooper();
您可以开始制作活套线了。
