【问题描述】：

我已关注this 文档以便能够接收 GCM 通知。 这是我的清单：

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

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

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

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <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="@string/google_android_api_key" />

    <activity
        android:name="com.evapp.activities.SplashActivity"
        android:label="@string/title_activity_splash" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.evapp.activities.LoginActivity"
        android:label="@string/title_activity_login" >
    </activity>
    <activity
        android:name="com.evapp.activities.RegistrationActivity"
        android:label="@string/title_activity_signup"
        android:parentActivityName="com.evapp.activities.LoginActivity" >

        <!-- Parent activity meta-data to support 4.0 and lower -->
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.evapp.activities.LoginActivity" />
    </activity>
    <activity
        android:name="com.evapp.activities.HomeActivity"
        android:label="@string/title_activity_home" >
    </activity>
    <activity
        android:name="com.evapp.activities.UserActivity"
        android:label="@string/title_activity_user" >
    </activity>
    <activity
        android:name="com.evapp.activities.TestActivity"
        android:label="@string/title_activity_test" >
    </activity>

    <receiver
        android:name="com.evapp.notification.Test"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <category android:name="com.evapp.notification" />
        </intent-filter>
    </receiver>

    <service android:name="com.evapp.activities.GcmIntentService" />
</application>

这里是WakefulBroadcastReceiver:

public class Test extends WakefulBroadcastReceiver


    @Override
    public void onReceive(Context context, Intent intent)
    
        Intent gcmIntent = new Intent(context, GcmIntentService.class);
        gcmIntent.putExtras(intent.getExtras());
        startWakefulService(context, gcmIntent);
        setResultCode(Activity.RESULT_OK);
    

还有IntentService：

public class GcmIntentService extends IntentService

    public static final int     NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    NotificationCompat.Builder  builder;

    public GcmIntentService()
    
        super("GcmIntentService");
    

    @Override
    protected void onHandleIntent(Intent intent)
    
        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        // The getMessageType() intent parameter must be the intent you received
        // in your BroadcastReceiver.
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty())
         // has effect of unparcelling Bundle
            /*
             * Filter messages based on message type. Since it is likely that
             * GCM will be extended in the future with new message types, just
             * ignore any message types you're not interested in, or that you
             * don't recognize.
             */
            if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
                    .equals(messageType))
            
                sendNotification("Send error: " + extras.toString());
             
            else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                    .equals(messageType))
            
                sendNotification("Deleted messages on server: "
                        + extras.toString());
                // If it's a regular GCM message, do some work.
             
            else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
                    .equals(messageType))
            
                // This loop represents the service doing some work.
                for (int i = 0; i < 5; i++)
                

                    try
                    
                        Thread.sleep(5000);
                     
                    catch (InterruptedException e)
                    
                    
                
                // Post notification of received message.
                sendNotification("Received: " + extras.toString());
            
        
        // Release the wake lock provided by the WakefulBroadcastReceiver.
        Test.completeWakefulIntent(intent);
    

    // Put the message into a notification and post it.
    // This is just one simple example of what you might choose to do with
    // a GCM message.
    private void sendNotification(String msg)
    
        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, HomeActivity.class), 0);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.calendar)
                .setContentTitle("GCM Notification")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    

从我的服务器端我收到了这个响应：

"multicast_id":7269872883857375111,"success":1,"failure":0,"canonical_ids":0,"results":["message_id":"0:1394655370108962%e210e99800364492"]

但是在调试时我永远不会进入GcmIntentService，调试器正在进入Test 类并且没有任何反应。

我错过了什么？看来startWakefulService 打不开GcmIntentService。

注意： 我已经按照@Eran 的建议更改了代码（仍然无法正常工作：()

【参考方案1】：

ComponentName comp = new ComponentName(context.getPackageName(),
                                       GcmIntentService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));

这仅在您的 GCMIntentService 类位于应用程序的主包中时才有效，我认为情况并非如此（因为您的接收器类位于不同的包中 - com.evapp.notification - 与应用程序的主包不同 - com.evapp.activities)。

你可以试试这样的：

Intent gcmIntent = new Intent(context, GcmIntentService.class);
gcmIntent.putExtras(intent.getExtras());
startWakefulService(context, gcmIntent);

【讨论】：

仍然没有，我是否也应该更改清单？这是gcmIntent (tosString()) Intent cmp=com.evapp.activities/com.evapp.notification.GcmIntentService (has extras) 的值

@VladIoffe 如果您发布完整清单，我将能够回答这个问题。

@VladIoffe 应用的包名是com.evapp.activities。该软件包名称应替换您拥有 com.example.gcm 的位置。

@VladIoffe 也应该替换<category android:name="com.evapp.notification" />中的包名。
