Link Of Class 'lcom/google/android/gms/gcm/gcmreceiver;' Failed

it's been two days that I'm on this Issue I'm trying to integrate GCM on an android app on eclipse environment. Everything works like a charm but once I have to receive the push

Solution 1:

I'm just going to go on a whim here and guess that the issue is either that you don't have support-v4 library included in your project (since com.google.android.gms.gcm.GcmReceiver extends android.support.v4.content.WakefulBroadcastReceiver) or your Eclipse project is misconfigured as described in this answer.

Disclaimer, I never used Eclipse, a quick googling on "Unable to resolve superclass" made me think this would be the answer.

Solution 2:

What is the intention of the notification in your application ? if only to notify and open certain activity , you should create your own BroadcastReceiver that will call a service and treat notification.

instead of using : android : name = "com.google.android.gms.gcm.GcmReceiver ", use : android : name = ".util_gcm.GcmBroadcastReceiver". that would be the way of your BroadCast.

Exemple BroadCast:

publicclassGcmBroadcastReceiverextendsWakefulBroadcastReceiver {

@OverridepublicvoidonReceive(Context context, Intent intent) {
    ComponentNamecomp=newComponentName(context.getPackageName(), GcmIntentService.class.getName());

    startWakefulService(context, (intent.setComponent(comp)));
    setResultCode(Activity.RESULT_OK);
}

}

This BroadCast call GcmIntentService, that treat notification. :

publicclassGcmIntentServiceextendsIntentService {
publicstaticfinalStringTAG="Script";
privatestaticfinalStringPREF_NAME="notification";


publicGcmIntentService(){
    super("GcmIntentService");
}

@OverrideprotectedvoidonHandleIntent(Intent intent) {
    Bundleextras= intent.getExtras();
    GoogleCloudMessaginggcm= GoogleCloudMessaging.getInstance(GcmIntentService.this);

    String title, cod, link,tipo, conteudo, messageType = gcm.getMessageType(intent);


    if(extras != null){
        if(GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)){
            Log.i(TAG, "Error: "+extras.toString());
        }
        elseif(GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)){
            Log.i(TAG, "Deleted: "+extras.toString());
        }
        elseif(GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)){

            title = extras.getString("titulo");

            link = extras.getString("link");
            tipo = extras.getString("tipo");


            //NotificationCustomUtil.sendNotification(GcmIntentService.this, title, cod,tipo);
                NotificationCustomUtil.sendNotification(GcmIntentService.this, title,tipo,link);
            }


        }
    }

    GcmBroadcastReceiver.completeWakefulIntent(intent);
}

}

Forget not to declare the service in manifest:

<serviceandroid:name=".util_gcm.GcmIntentService" ></service>

I hope you have helped in something . :)

Solution 3:

@Tunos, we can back track your set up of GCM for your android. Check the manifest files if you have included all required GCM permission:

<manifestpackage="com.example.gcm"...><uses-permissionandroid:name="android.permission.INTERNET" /><uses-permissionandroid:name="android.permission.WAKE_LOCK" /><uses-permissionandroid:name="com.google.android.c2dm.permission.RECEIVE" /><permissionandroid:name="com.example.gcm.permission.C2D_MESSAGE"android:protectionLevel="signature" /><uses-permissionandroid:name="com.example.gcm.permission.C2D_MESSAGE" /><application...
/></manifest>

implementation:

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

receiver and message handler:

<receiverandroid:name="com.google.android.gms.gcm.GcmReceiver"android:exported="true"android:permission="com.google.android.c2dm.permission.SEND" ><intent-filter><actionandroid:name="com.google.android.c2dm.intent.RECEIVE" /><categoryandroid:name="com.codepath.gcmquickstart" /></intent-filter></receiver>

These are only some of the checklist you should review in debugging your code. Here is the complete checklist regarding GCM. Also refer to this document.
