Launch Your Android App by Roger Deutsch

Launch Your Android App will teach you to develop Android Apps using Android Studio while walking 
through the creation of three complete apps. 
You will learn how to use various layouts and controls (ScrollView, ListViews and more). You'll learn how to 
create and write to files and the required permissions to allow apps to write to files. 
You'll learn Sqlite database creation with inserting and updating data while you create an app which allows 
you to Capture text data from other apps (QuoteCap). 
You'll learn all this and much more and I've written this book using a method which incorporates over 200 
images so you can see exactly what you will see when you sit down in front of Android Studio and develop 
your own apps.
