推荐答案

您可以在应用程序中捕获所有未捕获的异常扩展类。在异常处理程序中执行异常操作，并尝试设置AlarmManager以重新启动应用程序。这里是我应用程序中的例子，但是我只将数据库的异常记录到数据库。

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);
    }
}
