android 关于服务连接的疑问

[xidianluke]

已建立IMediaPlayService.aidl ，。。。有：boolean flag = this.bindService (mintent, serviceConn, Context.BIND_AUTO_CREATE);
if ( flag){
Log.i("system","**************** bindService is successful******");//这句输出了

}else {
Log.i("system","**************** bindService is failed ******");

}

private ServiceConnection serviceConn = new ServiceConnection() {

@Override
public void onServiceDisconnected(ComponentName name) {
Log.i("system","=========onServiceDisConnected==========");
mservice =null;
}

@Override
public void onServiceConnected(ComponentName name, IBinder service) {

mservice= IMediaPlaybackService.Stub.asInterface(service);
Log.i("system","=========onServiceConnected==========");

}
};
绑定服务 log显示绑定成功，但mservice 是空的 不知为何，？求指点

public void onServiceConnected(ComponentName name, IBinder service) 这个函数也没执行，怎么回事啊
