How to enable/ disable the GPS (toggle-ON/ OFF) from Android App by calling intent from AlertDialog?

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
