1.) Create a project named GetGSMPhoneLocation and set the information as stated in the image.

Build Target: Android 4.4
Application Name: GetGSMPhoneLocation
Package Name: com.example. GetGSMPhoneLocation
Activity Name: GetGSMPhoneLocationActivity

2.) Open GetGSMPhoneLocationActivity.java file and write following code there:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
