Hi Gurus,

I tried to use AeroGear and run into a little problem...

I installes Aerogear on OpenShift/Minishift incl Kerberos, like
https://github.com/aerogear/aerogear-unifiedpush-server/

After that I used the guide at:
https://aerogear.org/docs/unifiedpush/aerogear-push-android/guides/

Then I got a complier error when I tried to run the  PushApplication

Error:(25, 23) error: TAG has private access in FragmentActivity

I tried to fixed this in
MainActivity.java by adding a
    private static final String TAG = MainActivity.class.getSimpleName();


So I got the following error at application runtime:
W/System: ClassLoader referenced unknown path: /data/app/com.push.pushapplication-1/lib/arm64
I/FirebaseInitProvider: FirebaseApp initialization unsuccessful
I/InstantRun: starting instant run server: is main process
