NoClassDefFoundError: android.support.v4.app when sending push?

Question

Im using PushBots to manage my push notifications for my app, I have been using this amazing platform for lots of apps and its the first time I have a problem like this.

Sometimes, when I launch the app, I get this error, but always when receiving a push (within or whitout the app opened).

07-12 01:20:00.844: E/AndroidRuntime(12140): FATAL EXCEPTION: IntentService[GCMIntentService-326*****5*9-1]

Im pretty sure this is about the android support v4, this is my current build path:

*Sometimes when I uncheck the Private Libraries clean and re-check this option again the app works (but not lucky with notifications).

The support v4 jar is in the libs folder, the route is the correct (MyApp/libs)

Im about to release an update, my app is already working/running with pushbots servers (with registered devices and all) so I would like to solve this to release my update. Thanks.

Answer 1

As explained in these questions: NotificationManagerCompat Can't be resolved - Android Wear and Android studio unable to import WearableExtender NotificationManagerCompat and RemoteInput. It seems that you are not using the last version of the compatibility support library. You have two options to solve that:

1. Download the newest libraries manually, and add them to your project.

2. It seems that you are using eclipse, I recommend that you now use Android Studio so you can add the dependency and let gladle handle the libraries, like this

   dependencies {
       compile 'com.android.support:support-v4:20.0+'
   }
   

Answer 2

check mark the following jars in build path or property ,it will work 1. android-support-v4.jar(appcombat/ibs) 2.android-support-v4-appcombat.jar(appcombat/ibs)
