private final Handler mHandler = new Handler(Looper.getMainLooper()) {

case APPLE_INFO:

//观察者模式,通知所有客户端
final int clientNum = mCallbacks.beginBroadcast();
for (int i = 0; i < clientNum; i++) {
IRemoteServiceCallBack callBack = mCallbacks.getBroadcastItem(i);
if (callBack != null && apple != null) {
try {
callBack.noticeAppleInfo(apple);
} catch (RemoteException e) {
e.printStackTrace();

}
mCallbacks.finishBroadcast();应该放到for循环后面,不然通知一个就结束了
