PrayerTime-Android is available on Google Play Store as Salaat Time.
Install Salaat Time from Google Play
The Salaat time calculations are based on the Prayer-Times library. It has been modified to allow it to be used with the app and to make the code consistent with Java conventions.
You should be able to setup the project in Android Studio 1.3+. The string resource for the Google Maps API key has not been included. You may get a compile time exception that a string resource is missing:
Error:(82, 29) No resource found that matches the given name (at 'value' with value '@string/secret_google_maps_api_key').
In order to resolve this, you just need to define a string resource under strings.xml simply add:
<string name="secret_google_maps_api_key">your API key</string>
