问题描述
这是在我的 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();
}
}
};
我学习了这个关于 GCM 的教程
I followed this tutorial about GCM

推荐答案
通过滑动关闭应用(通常称为滑动它)并不完全杀死应用程序.查看 Android 爱好者社区中的此答案，了解更详细的说明.你可以看到那里提到:
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 通知的侦听器是 Service，这实际上意味着您的应用仍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.
虽然滑动应用的结果也可能会有所不同取决于正在运行的设备，但可能会杀死/强制停止它，或者如上所述，会停止后台进程.
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，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:
对于停止是完全终止应用程序 - 所有进程都被终止，所有服务停止，所有通知被移除，所有警报被移除，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.
这将导致应用程序根本不会收到任何类型的通知，因为它是从 3.1 版开始为 Android 设计的，如本 回答:
Which would result for the app to don't receive any kind of notifications at all, as it was designed for Android since version 3.1, as stated in this answer:
处于停止状态的应用不会收到广播 Intent.
停止状态是:
最初安装应用时(在用户在应用中运行某些内容之前)或强制停止后.您可以在此处找到更多相关信息: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一些东西.干杯!:D
Hope this helps clear some things somehow. Cheers! :D
这篇关于即使应用程序关闭(滑动/滑动)也能接收 GCM 通知的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持编程学习网！
