Worklight app crashes when receiving push notification

Question

Hi I have developed a Worklight application for android which uses Bluemix IBM Push, when I receive the notification, if the app is closed, it works fine and opens the app, but when the app is open the app crashes with the following error.

Answer 1

Have you tried editing your AndroidManifest.xml to remove the references to GCMIntentService?

You might be able to comment out the sections as explained here: https://developer.ibm.com/answers/questions/19343/double-push-notifications/?smartspace=bluemix

That way you will be only using the Bluemix Push SDK to respond to push notifications. Hopefully avoiding that error entirely.

EDIT : After some playing around I figured out that the Push plugin was to blame for the conflicting SDKs. After I commented out the Worklight Push plugin in the config.xml the error disappeared.

Comment these lines and try again:

<feature name="Push">
     <param name="android-package" value="com.worklight.androidgap.plugin.Push" />
</feature>
