Elasticsearch + WhatElse？(Elasticsearch + WhatElse? [closed])

 要获得您的问题的答案非常简单。 在这种情况下，你需要使用Thread.setDefaultUncaughtExceptionHandler（）。 如果您的应用程序崩溃，它将始终输入uncaughtException（） 
 
public class YourApplication extends Application {

    private static Context mContext;

    public static YourApplication instace;

    @Override
    public void onCreate() {
        super.onCreate();
        mContext = getApplicationContext();
        instace = this;
    }

    @Override
    public Context getApplicationContext() {
        return super.getApplicationContext();
    }

    public static YourApplication getIntance() {
        return instace;
    }
}

    public DefaultExceptionHandler(Activity activity) {
        this.activity = activity;
    }

    @Override
    public void uncaughtException(Thread thread, Throwable ex) {

        try {

            Intent intent = new Intent(activity, RelaunchActivity.class);

            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                    | Intent.FLAG_ACTIVITY_CLEAR_TASK
                    | Intent.FLAG_ACTIVITY_NEW_TASK);

            PendingIntent pendingIntent = PendingIntent.getActivity(
                    YourApplication.getInstance().getBaseContext(), 0, intent, intent.getFlags());

                        //Following code will restart your application after 2 seconds
            AlarmManager mgr = (AlarmManager) YourApplication.getInstance().getBaseContext()
                    .getSystemService(Context.ALARM_SERVICE);
            mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 1000,
                    pendingIntent);

                        //This will finish your activity manually
            activity.finish();

                        //This will stop your application and take out from it.
            System.exit(2);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

To get Answer of your question is very simple. In that case you need to use Thread.setDefaultUncaughtExceptionHandler(). It will always enter in uncaughtException() in case your application crashed.For Check Full Tutorial Here
