Android Service系列（八）实操一下Service

service代码如下，清单文件已经申明

public class TestService extends Service { private static final String TAG = "TestService"; @Nullable @Override public IBinder onBind(Intent intent) { Log.i(TAG,"onBind"); return new Binder(); } @Override public int onStartCommand(Intent intent, int flags, int startId) { Log.i(TAG,"onStartCommand"); return super.onStartCommand(intent, flags, startId); } }

下面不停调用startService

发现：每调用一次  startService   Service的onStartCommand 就执行一次

 

不停调用bindService

bindService代码如下

bindService(new Intent(this, TestService.class), new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { Log.i(TAG,"onServiceConnected"); } @Override public void onServiceDisconnected(ComponentName name) { Log.i(TAG,"onServiceDisconnected"); } },BIND_AUTO_CREATE);

发现，第一次是onBind调用，后面每次调用bindService，onServiceConnected就会回调一次，但是Serviced onBind方法则不再调用！

看来和startService还有些区别
