i get an error in logcat when the app tries to to start onLocationChanged, stating that camera update is not initialized, is there something im missing or doing wrong?
all this code works when trying on a separate activity but i need this to work in a fragment for 3 tab.
I appreciate your help and advice, even if this is a silly question
