class not found exception GCMIntentServices on path DexPathList

问题

i have checked most of the available material on GcmIntentServices but couldn't figure out the problem i am facing..

The Push notification code is provided on the login page and the next page is homeScreen, but the intent occurs without fail.. yet after some time on the home page.. the app crashes..

my log cat provides the following error..

 E/AndroidRuntime(1449): FATAL EXCEPTION: main

回答1:

ok you need to fix the PackageName in the Manifest use:

<service android:name="com.quinoid.sms.pushnotifications.GCMIntentService" />

回答2:

You have two packages.So while registering the GCM service specify the package.GCMIntentService
