Activity com.facebook.FacebookActivity 泄露了原本绑定在这里的ServiceConnection com.google.android.gms.common.zza

Question

在Signing In 之后我开始MainActivity 然后我添加了gcm，如下所示：

mRegistrationBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                SharedPreferences sharedPreferences =
                        PreferenceManager.getDefaultSharedPreferences(context);
                boolean sentToken = sharedPreferences
                        .getBoolean(Constants.SENT_TOKEN_TO_SERVER, false);
                if (sentToken) {
                    Log.d(TAG, "Token retrieved and sent to server!");
                } else {
                    Log.d(TAG, "An error occurred while either fetching the InstanceID token,\n" +
                            "        sending the fetched token to the server or subscribing to the PubSub topic. Please try\n" +
                            "        running the sample again.");
                }
            }
        };

        registerReceiver();
        if (checkPlayServices()) {
            // Start IntentService to register this application with GCM.
            Intent intent = new Intent(this, RegistrationIntentService.class);
            startService(intent);
        }

然后出现错误

如果我删除 gcm 代码并删除应用程序并再次安装它会正常工作。

我尝试在MainActivity 上进行调试，但我不能。我不知道根本原因是什么以及如何找出问题所在。

Answer 1

错误消息基本上意味着某些组件创建了与'service' 的绑定，并且在组件被销毁之前没有与服务解除绑定。

Android 运行时在 onHandleIntent() 完成后销毁 'IntentService' 并且没有更多 Intent 请求排队。您可以通过将“onDestroy()”方法添加到您的 IntentService 来确认这一点，并在日志中显示它何时被调用。

如果在此服务仍在运行的情况下销毁您的应用，则该服务不再具有用途。它将存在于内存中消耗资源但什么都不做。通过在完成后解除绑定或停止服务，您可以返回这些资源，以便其他应用可以使用它们。

这是一个相关的stack overflow ticket，它讨论了活动泄漏其服务连接。
