Service 中的 onStart 和 onStartCommand
在自定义的service中,写了onStart和onStartCommand,
public class HttpWebService extends Service {
@Override
public void onCreate() {
super.onCreate();
.... @Override public void onStart(Intent intent, int startId) { // this will trigger AbstractBackgroundService.onStart() super.onStart(intent, startId); Log.d(LOG_TAG, "onStart" + intent); } @Override public int onStartCommand(Intent intent, int flags, int startId) { int retVal = super.onStartCommand(intent, flags, startId); Log.d(LOG_TAG, "onStartCommand" + intent); return retVal; } }
如果用 bindService 这种方式调用,onStart和onStartCommand都不会被调用到
this.bindService(new Intent(this, HttpWebService.class), new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { HttpWebService webService = ((HttpWebService.LocalBinder) service) .getService(); webService.SetServerListener(webListener); } @Override public void onServiceDisconnected(ComponentName name) { } }, Context.BIND_AUTO_CREATE);
如果是用StartService调用,两个都被调用到
Intent intent = new Intent("com.example.sharefiles.services.ShareServices.Test"); intent.setClass(getApplicationContext(), HttpWebService.class); intent.putExtra("enable", true); this.startService(intent);

onStart(Intent intent, int startId)
This method was deprecated in API level 5. Implement
onStartCommand(Intent, int, int)
instead.onStartCommand(Intent intent, int flags, int startId)
Called by the system every time a client explicitly starts the service by calling
startService(Intent)
, providing the arguments it supplied and a unique integer token representing the start request.鉴于目前的代码基本都是运行在API5 以上的,所以直接干掉onStart.
