接收Android通知

Question

我已按照this文檔進行操作，以便能夠接收GCM通知。 這裏是我的清單：

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

<uses-feature 
    android:glEsVersion="0x00020000" 
    android:required="true" /> 
<uses-feature android:name="android.hardware.camera" /> 

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

這裏是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); 
    } 

} 

而且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()); 
    } 
} 

從我的服務器端我得到這樣的響應：

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

但調試我從來沒有漸入GcmIntentService時，調試器進入了Test類並沒有任何反應。

我缺少什麼？看來startWakefulService不開放GcmIntentService。

注： 我修改了代碼@Eran建議（仍然沒有工作:(）

Answer 1

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

如果您GCMIntentService類是在你的應用程序，主要包這隻會工作，其我認爲不是這樣的（因爲您的接收器類是在不同的包 - com.evapp.notification - 比你的應用程序的主包 - com.evapp.activities）

你可以嘗試這樣的事情，而不是：

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