【问题描述】：

我创建了一个应用程序，它从我的服务器接收 GCM 消息。我试图实现为 google 的示例 (http://developer.android.com/google/gcm/client.html#sample-receive)。除非出现问题，否则它可以正常工作。也就是说，如果我在内存中杀死了我的应用程序，我的广播接收器将永远不会收到 GCM 消息。 我尝试获取设备日志，发现此问题与 GTalkService 有关：

01-15 14:19:40.509: W/GTalkService(1300): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent  act=com.google.android.c2dm.intent.RECEIVE pkg=com.paktor (has extras) 
01-15 14:19:40.750: W/GTalkService(1300): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent  act=com.google.android.c2dm.intent.RECEIVE pkg=com.paktor (has extras) 
01-15 14:19:41.090: W/GTalkService(1300): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent  act=com.google.android.c2dm.intent.RECEIVE pkg=com.paktor (has extras) 

我的接收器在 manifest.xml 中：

   <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND"  >
       <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.paktor" />
        </intent-filter>
    </receiver>

更新： 我的广播：

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver 

@Override
public void onReceive(Context context, Intent intent) 
    Log.i(this, "Receive GCM message");
    // 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);

和权限：

  <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />

我不知道为什么。每件事看起来都很正常。请帮助我了解如何在我的应用程序被杀死时捕获 GCM 消息。

【问题讨论】：

我认为你需要在 android 中看到 WakeLocker。 developer.android.com/reference/android/os/…

我加了android.permission.WAKE_LOCK没问题

【参考方案1】：

像这样制作WakefulBroadcastReceiver

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);
    

还有权限

    <!-- App receives GCM messages. -->
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <!-- GCM requires a Google account. -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <!-- Keeps the processor from sleeping when a message is received. -->
    <uses-permission android:name="android.permission.WAKE_LOCK" />

【讨论】：

我之前是这样实现的。我想这不是问题

【参考方案2】：

发送gcm消息时设置delay_while_idle=0
