即使关闭应用程序(滑动/滑动)，仍会收到GCM通知 [英] Receive GCM notification even when the app is closed (slide/swiped away)

问题描述

这是MainActivity中用作BroadcastReceiver的代码

Here is the code that is used as BroadcastReceiver inside my MainActivity

    mRegistrationBroadcastReceiver = new BroadcastReceiver() {

        //When the broadcast received
        //We are sending the broadcast from GCMRegistrationIntentService

        @Override
        public void onReceive(Context context, Intent intent) {
            //If the broadcast has received with success
            //that means device is registered successfully
            if(intent.getAction().equals(GCMRegistrationIntentService.REGISTRATION_SUCCESS)){
                //Getting the registration token from the intent
                String token = intent.getStringExtra("token");
                //Displaying the token as toast
                Toast.makeText(getApplicationContext(), "Registration token:" + token, Toast.LENGTH_LONG).show();

                //if the intent is not with success then displaying error messages
            } else if(intent.getAction().equals(GCMRegistrationIntentService.REGISTRATION_ERROR)){
                Toast.makeText(getApplicationContext(), "GCM registration error!", Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(getApplicationContext(), "Error occurred", Toast.LENGTH_LONG).show();
            }
        }
    };

我遵循了有关GCM的本教程

I followed this tutorial about GCM

推荐答案

通过滑动来关闭应用程序(通常称为 将其清除 )并不完全杀死应用程序.在Android发烧友社区中查看 answer 以获得更详细的描述.您可以在那里看到其中提到的内容:

Closing the app by sliding it (more commonly known as swiping it away) doesn't totally kill the app. Check out this answer in Android Enthusiasts community for a more detailed description. You can see there that it is mentioned that:

..它不会直接导致服务停止..

..It won't directly causes services to stop..

由于GCM通知的侦听器为Service，这实际上意味着您的应用仍然有可能继续接收它们，无论它是否被 刷掉 .

Since listeners for GCM notifications are Services, this would actually mean that there is still a possibility that your app may still continue to receive them regardless if it is swiped away.

尽管滑动应用程序的结果也可能因运行的设备而有所不同 ，但可能会杀死/强制停止运行该应用程序，或者如上所述，将停止后台进程.

Though the result of swiping an app may also differ depending on the device it is running, one may kill/force stop it or other just as mentioned above, will stop background processes.

但是，如果结果是，则该应用程序被杀死/强制停止，如上面链接的答案中所述:

If the result is, however, the app is killed/force stopped, as mentioned in the answer from the link above:

要停止，就是完全杀死了该应用程序–所有进程都被杀死，所有服务已停止，已删除所有通知，已删除所有警报，等等.

For stop is a complete kill of the app -- all processes are killed, all services stopped, all notifications removed, all alarms removed, etc.

如本

处于停止状态的应用不会收到广播的Intent.

停止状态是:

最初安装应用程序时(在用户在应用程序中运行某些程序之前)或 强制停止后. 您可以在此处找到有关此内容的更多信息: http://developer.android.com/about/versions/android-3.1.html#launchcontrols

when the app is initially installed (before the user runs something in the app) or after a Force Stop. You can find more about this here: http://developer.android.com/about/versions/android-3.1.html#launchcontrols

希望这有助于以某种方式清除某些内容.干杯! :D

Hope this helps clear some things somehow. Cheers! :D
