您可以在应用程序扩展类中捕获所有未捕获的异常.在异常处理程序中对异常执行一些操作并尝试设置 AlarmManager 以重新启动您的应用程序.这是我如何在我的应用程序中执行此操作的示例，但我只将异常记录到数据库.

You can catch all uncaught exceptions in your Application extension class. In the exception handler do something about exception and try to set up AlarmManager to restart your app. Here is example how I do it in my app, but I only log exception to a db.

public class MyApplication extends Application {
    // uncaught exception handler variable
    private UncaughtExceptionHandler defaultUEH;

    // handler listener
    private Thread.UncaughtExceptionHandler _unCaughtExceptionHandler =
        new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread thread, Throwable ex) {

                // here I do logging of exception to a db
                PendingIntent myActivity = PendingIntent.getActivity(getContext(),
                    192837, new Intent(getContext(), MyActivity.class),
                    PendingIntent.FLAG_ONE_SHOT);

                AlarmManager alarmManager;
                alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
                alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 
                    15000, myActivity );
                System.exit(2);

                // re-throw critical exception further to the os (important)
                defaultUEH.uncaughtException(thread, ex);
            }
        };

    public MyApplication() {
        defaultUEH = Thread.getDefaultUncaughtExceptionHandler();

        // setup handler for uncaught exception 
        Thread.setDefaultUncaughtExceptionHandler(_unCaughtExceptionHandler);
    }
}
