How to get the speed of a vehicle using your phone when we seated in the vehicle using GPS in Android latest version. I have used the GPS_PROVIDER location.getSpeed() and its not working. I have used the below mentioned code which is not working and my phone Model is Samsung m21 (Android 12 OS).
In the below code onLocationChanged @Override function is not working.
- Can we track speed with GPS provider in latest (Android 12) phones?
If it is possible please let me know the new process of getting the speed of vehicle using GPS provider.
Appreciate the help, Thanks.
