GCM BroadcastReceiver只有當應用程序正在運行或在後臺運行時纔會觸發

Question

我已經實現了GCM服務，並且它一切正常，但當我關閉應用程序後應該收到通知時（通過長按Home鍵，然後在垃圾圖標 - Galaxy S III），我沒有收到它。

這裏是我的的Manifest.xml：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.proj" 
    android:versionCode="1" 
    android:versionName="1.0" > 

    <uses-sdk 
     android:minSdkVersion="12" 
     android:targetSdkVersion="18" />

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/> 
    <uses-permission android:name="android.permission.CALL_PHONE" /> 
    <!-- The following two permissions are not required to use 
     Google Maps Android API v2, but are recommended. --> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    <uses-permission android:name="com.example.proj.permission.C2D_MESSAGE" /> 


    <uses-feature 
     android:glEsVersion="0x00020000" 
     android:required="true"/> 
    <application 
     android:allowBackup="true" 
     android:icon="@drawable/projicon" 
     android:label="@string/app_name" 
     android:theme="@style/Theme.Sherlock" 
     android:uiOptions="splitActionBarWhenNarrow" > 
     <activity 
      android:name="com.example.proj.FbActivity" 
      android:label="@string/app_name" 
      android:configChanges="keyboardHidden|orientation|screenSize" 
      android:uiOptions="splitActionBarWhenNarrow"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
      <meta-data 
      android:name="com.google.android.gms.version" 
      android:value="@integer/google_play_services_version" /> 
      <meta-data 
     android:name="com.google.android.maps.v2.API_KEY" 
     android:value="APIKEY"/> 
     <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id"/> 
     <activity android:name="com.facebook.LoginActivity"></activity> 
     <activity android:name="MainActivity" 
      android:configChanges="keyboardHidden|orientation|screenSize"></activity> 

     <receiver 
      android:name="com.example.proj.GcmBroadcastReceiver" 
      android:permission="com.google.android.c2dm.permission.SEND" > 
      <intent-filter> 
       <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
       <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); 
    } 

} 

我不知道如果通過我做的方式關閉應用程序殺死應用程序成功或者它仍然應該在後臺運行，並接受這些masseges。

我有同樣的問題，我發現我做的清單文件出錯：

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

應該是：

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

在應用程序包是包含包類擴展Application（並且應該指向清單文件）。

解決此問題後，我已經能夠強制關閉我的應用程序，並仍然通過GCM接收推送通知。
