程序异常后自动

public class DemoApplication extends Application implements Thread.UncaughtExceptionHandler{private PendingIntent pendingIntent;@Overridepublic void onCreate() {super.onCreate();Thread.setDefaultUncaughtExceptionHandler(this);}@Overridepublic void uncaughtException(Thread thread, Throwable ex) {        Intent intent = new Intent(this, MainActivity.class);         pendingIntent=  PendingIntent.getActivity(getApplicationContext(), -1, intent, (Intent.FLAG_ACTIVITY_CLEAR_TOP |  Intent.FLAG_ACTIVITY_NEW_TASK));        AlarmManager mgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);          mgr.set(AlarmManager.RTC, 0 , pendingIntent);        System.exit(0);  

}

程序发生运行时异常时，这个Application会自动捕捉异常，并重启启动app，亲测，ok
