5 minute speedometer in android studio

How to make quick 5 min speedometer in Android studio
Code is on github: https://github.com/dbojan/5MinuteSpeedometer

Based on 5 Minute Android Speedometer ( https://www.youtube.com/watch?v=bYiOdw4mDnQ&t=622s ), and some parts from
Develop Simple Speedometer in Android Studio ( https://www.youtube.com/watch?v=tRTX7Jere6E , Interesting stuff starts around 17 minute, iBaseGpsListener will be deleted!).

You can also download android gps apps projects for Android studio from github:

Basically you have to ask user for fine location (gps) permission, because of the changes in android 6.

The easiest way for this to work in Android Studio is to add this in main activity:
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);

Longer way is described in this video.
