Android UncaughtExceptionHandler 不工作

Question

我正在创建一个启动器。有时我会遇到错误，当然我必须修复它们，但我正在尝试为我的整个应用程序使用 UncaughtExceptionHandler。

为此我使用了这个类:

  public class clsMyApplication 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) 
        {
           try
           {  Save a log file with the error and 
              save preferences indicating there was an error to display the next start up.
           }
           catch(Exception e)
           {

           }



           //Alarm to restart app:
           PendingIntent myActivity = PendingIntent.getActivity(clsMyApplication.this, 192837, new Intent(clsMyApplication.this, clsMyMainActivity.class), PendingIntent.FLAG_ONE_SHOT);
           AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
           alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 5000, myActivity );
           System.exit(2);


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

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

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


  }

我还像这样将此类添加到 list 中:

<application       
    android:name=".clsMyApplication"         
    ....

但我仍然遇到 Android 异常。我无法让他们使用此类。有帮助吗？

将这行代码添加到任何方法中(最好是在 OnCreate Activity 中)

Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {

        @Override
        public void uncaughtException(Thread thread, Throwable t) {
            //Do something
        }
    });
