在未捕获异常的情况下重启停止了的服务

    }



    @Override

        return mBinder;
    }

    public class MyBinder extends Binder {
        UpdateService getService() {
            return UpdateService.this;
        }
    }


    public Thread.UncaughtExceptionHandler onForceCloseError= new Thread.UncaughtExceptionHandler() {

            Log.v("Service stopped", "Service  stopped after force close error ...");


            Log.v("Service started", "Service  started after force close error ...");

        } };

        private UpdateService s;

        private ServiceConnection mConnection = new ServiceConnection() {

            public void onServiceConnected(ComponentName className, IBinder binder) {
                s = ((UpdateService.MyBinder) binder).getService();

            }

            public void onServiceDisconnected(ComponentName className) {
                s = null;
                Log.v("Update Servicve","Service Disconnected...");
            }
        };

        void doBindService() {
            bindService(new Intent(this, UpdateService.class), mConnection,
                    Context.BIND_AUTO_CREATE);
            Log.v("bindService", "bindService called...");

        }

}

在android有上述服务代码。系统提醒我获得未捕获的异常,且服务也停止了。执行线程进入UnCaughtExceptionHandler状态。我重新启动服务,但是启动不了。问题出在哪里啊?

如果服务被终止,你可以使用STARTSTICKY来重启服务。只是你要返回onStartCommand(Intent, int, int)方法中的STARTSTICKY

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

      return Service.START_STICKY;
}

在service class中使用这个方法:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return Service.START_STICKY;
}
