I'm trying to build a
Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.
google.android.gms.checkin
A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener.
The problem is that when I start the application I get this message:
I have all my libraries imported properly and I even added the google-play-services.jar into my libs folder. I also installed
Google Play Services APKs through CMD onto my emulator.
Furthermore the LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); in my GPSTrack class always returns null.
Why is this and how can I fix these issues? Would appreciate an explanation along with solution too, I want to understand what's going on here.
