GCM BroadcastReceiver只有在应用程序正在运行或在后台运行时才会触发 [英] GCM BroadcastReceiver fired only when app is running or running at background

问题描述

我已经实施了GCM服务，并且一切正常，但是当我关闭应用程序后应该收到通知时（通过长按主屏幕按钮，然后是垃圾图标 - Galaxy S III），我不会

以下是我的 Manifest.xml ：

 <？xml version =1.0encoding =utf-8？> 
< manifest xmlns：android =http://schemas.android.com/apk/res/android

< / intent-filter> 
< / receiver> 
< service android：name =com.example.proj.GcmIntentService/> 
< / application> 
< / manifest> 
  

GcmBroadcastReceiver.java：

  public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
 $ b $ @Override 
 public void onReceive（Context context，Intent intent）{
 / /明确指定GcmIntentService将处理意图。 
 ComponentName comp = new ComponentName（context.getPackageName（），
 GcmIntentService.class.getName（））; 
 //启动服务，保持设备在启动时保持清醒状态。 
 startWakefulService（context，（intent.setComponent（comp）））; 
 setResultCode（Activity.RESULT_OK）; 
} 
 
} 
  

我不确定是否按以我杀死应用程序的方式关闭应用程序，或者它仍然应该在后台运行并接收这些管理员。

解决方案

我有同样的问题，我发现我在清单文件中犯了一个错误：

 < permission android：name =com.example.gcm.permission.C2D_MESSAGE
 android：protectionLevel =signature/> 
<使用权限android：name =com.example.gcm.permission.C2D_MESSAGE/> 
  

应该是：

 < permission android：name =< your app package> .permission.C2D_MESSAGE
 android：protectionLevel =signature/> 
< uses-permission android：name =< your app package> .permission.C2D_MESSAGE/> 
  

其中应用程序包是包含扩展应用（并且应该在清单文件中指出）。

After修复此问题，我已经能够强制关闭我的应用程序，并仍然通过GCM接收推送通知。

I've implemented GCM service and it all works fine but when I'm supposed to recieve a notification after I closed the app (By long click at home button and then at the garbage icon - Galaxy S III), I don't recieve it.

Here's my Manifest.xml:

  <?xml version="1.0" encoding="utf-8"?>

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
          <meta-data

        <receiver

                <category android:name="com.example.proj" />
            </intent-filter>
        </receiver>
        <service android:name="com.example.proj.GcmIntentService" />
    </application>
</manifest>

GcmBroadcastReceiver.java:

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }

}

I'm not sure if by closing the app by the way I did kills the app proccess or it still should be running at the background and recieve those masseges.

解决方案

I had the same problem, and I found out I made a mistake in the manifest file:

<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />
    <uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />

should be:

<permission android:name="<your app package>.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="<your app package>.permission.C2D_MESSAGE" />

where the app package is the package that contains the class that extends Application (and should be pointed in the manifest file).

After fixing this, I've been able to force close my app and still receive push notifications via GCM.
