Android - nicht GCM bekommen Token

Question

ich RegistrationIntentService nennen:

if (checkPlayServices()) { 
     Log.i("udazzT", "check servicies"); 
     // Start IntentService to register this application with GCM. 
     Intent intent2 = new Intent(this, RegistrationIntentService.class); 
     startService(intent2); 
    } 

Aber ich kann nicht der Protokolle in RegistrationIntentService sehen:

public class RegistrationIntentService extends IntentService { 

    private static final String TAG = "RegIntentService"; 
    private static final String[] TOPICS = {"global"}; 

    public RegistrationIntentService() { 
     super(TAG); 
    } 

    @Override 
    protected void onHandleIntent(Intent intent) { 
     Log.i("udazzT", "setting token"); 
     SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this); 

     try { 
      // In the (unlikely) event that multiple refresh operations occur simultaneously, 
      // ensure that they are processed sequentially. 
      synchronized (TAG) { 
       // [START register_for_gcm] 
       // Initially this call goes out to the network to retrieve the token, subsequent calls 
       // are local. 
       // [START get_token] 
       Log.i("udazzT", "setting token 2"); 
       InstanceID instanceID = InstanceID.getInstance(this); 
       String token = instanceID.getToken(getString(R.string.gcm_defaultSenderId), 
         GoogleCloudMessaging.INSTANCE_ID_SCOPE, null); 
       // [END get_token] 
       Log.i(TAG, "GCM Registration Token: " + token); 

       // TODO: Implement this method to send any registration to your app's servers. 
       sendRegistrationToServer(token); 

       // Subscribe to topic channels 
       subscribeTopics(token); 

       // You should store a boolean that indicates whether the generated token has been 
       // sent to your server. If the boolean is false, send the token to your server, 
       // otherwise your server should have already received the token. 
       sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, true).apply(); 
       // [END register_for_gcm] 
      } 
     } catch (Exception e) { 
      Log.d(TAG, "Failed to complete token refresh", e); 
      // If an exception happens while fetching the new token or updating our registration data 
      // on a third-party server, this ensures that we'll attempt the update at a later time. 
      sharedPreferences.edit().putBoolean(QuickstartPreferences.SENT_TOKEN_TO_SERVER, false).apply(); 
     } 
     // Notify UI that registration has completed, so the progress indicator can be hidden. 
     Intent registrationComplete = new Intent(QuickstartPreferences.REGISTRATION_COMPLETE); 
     LocalBroadcastManager.getInstance(this).sendBroadcast(registrationComplete); 
    } 

    /** 
    * Persist registration to third-party servers. 
    * 
    * Modify this method to associate the user's GCM registration token with any server-side account 
    * maintained by your application. 
    * 
    * @param token The new token. 
    */ 
    private void sendRegistrationToServer(String token) { 
     // Add custom implementation, as needed. 
    } 

    /** 
    * Subscribe to any GCM topics of interest, as defined by the TOPICS constant. 
    * 
    * @param token GCM token 
    * @throws IOException if unable to reach the GCM PubSub service 
    */ 
    // [START subscribe_topics] 
    private void subscribeTopics(String token) throws IOException { 
     for (String topic : TOPICS) { 
      GcmPubSub pubSub = GcmPubSub.getInstance(this); 
      pubSub.subscribe(token, "/topics/" + topic, null); 
     } 
    } 
    // [END subscribe_topics] 

} 

Answer 1

Vergewissern Sie sich, dass es in Ihrem Manifest registriert ist.

<service android:name=".RegistrationIntentService" 
      android:exported="false" /> 

Answer 2

Hast du gedacht, hinzufügen alle hier benötigt wird, wie googlesamples

Answer 3

Gerade dieses Add

<intent-filter> 
<action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
<category android:name="<PACKAGE-NAME>" /> 
</intent-filter> 

in manifest.xml von "GcmReceiver" & "MyGcmListenerService" in meinem Code ist es aussieht Wie unten.

In meinem Fall funktioniert es ... Vielleicht ist es hilfreich für Sie. Best Of Luck

überprüfen, ob Sie unter der Linie in Empfängern Intent-Filter hinzugefügt haben

Seit seiner in GCM doc erwähnt als:

Wenn Sie pre-4.4 KitKat Geräte unterstützen möchten, fügen Sie die folgende Aktion auf die Absicht Filter Erklärung für den Empfänger:
