Track your friend's location or share your own.
I have created three activities in android studio, the first one is the main launcher activity (MainActivity.java) in which the user can select whether to share his location or to track his friend’s location by inputting his coordinates. The second activity (MapsActivity.java) loads when the user decides to track someone’s location in the main activity. The third activity (ShareActivity.java) loads when the user decides to share his/her location. This activity asks for the user's location permission before displaying his coordinates. There's also a button to copy the user's coordinates to the clipboard if he decides to share it with his friends.
