我创建了一个使用检查朋友请求的服务。我想知道为什么“用户名”在logcat中重复出现以及如何解决它。我有一个悲伤的问题，就是谁知道如何通过数据到ThirdActivity的BroadcastReceiver ?? Log.d（“admin”，result）显示了朋友的名字但是为什么它不能在ThirdActivity中通知？ （我在ThirdActivity中更新了一些内容并在登录前添加了logcat）

我使用解锁事件来呼叫服务。因此，当我解锁我的设备时，我可以获得我的朋友用户名，即EnEn，它应该被发送到ThirdActivity，它将通知用户得到朋友的请求。但问题是，sendBroadcast（意图）不起作用。它在这里停了下来。按下登录按钮并启动ThirdActivity之后，我收到了无限通知，显示“abc已向您发送了一个朋友请求”（我在ThirdActivity中修改了onReceive（））。这意味着MyService的数据没有传递给ThirdAcitvity，当我登录时，MyService开始与ThirdAcitvity通信，但它没有通过。我怀疑这个问题可能是由于文件输入和输出导致的，用于保存用户的用户名和加载用户的用户名。 ** MainActivity是登录页面。
任何人都可以帮忙吗？提前谢谢。
