How to Make Android Apps 23
In this tutorial we’ll make an Android Google Map example program. Along with that I’ll also show how to create a splash screen and how to sign your APKs so you can distribute your app.
If you combine what I cover here with my Android ActionBar tutorial you’ll be able to add more functionality to your Google Map quite easily. All of the code used can be found after the video below.
