helo, i have a strange problem with app - when i use google's api for user location, the gps starts in second and goes to locate. but if i use mapbox, it takes up to 15 minutes to do what it does, then i have to turn off the screen and on again to show the gps logo at the bottom of the screen, then to turn off and on again to begin location. what could makes that. I have searched everywhere on the web for similar problems, but I found nothing. I used everything as it is described in http://www.mapbox.com for making it, and the problem still exists. Here is the code of Main activity:
