In this video it shows how one can toggle the GPS settings ON and OFF by calling the respective intent from the Android App.

It uses the ACTION_LOCATION_SOURCE_SETTINGS intent to open the respective settings to be toggled by the user.

I hope you like this video. For any questions, suggestions or appreciation please contact us at: https://programmerworld.co/contact/ or email at: programmerworld1990@gmail.com
