A good starter app for a noobie Android developer

Does anyone know a starter app for a noobie Android developer? An app you can modify/hack/develop based on it, as a starter app. Like Underscores is for WordPress. Thanks!

1.Android Studio Development Essentials
2.Learn Android Studio: Build Android Apps Quickly and Effectively
3.The Android Developer’s Cookbook: Building Applications with the Android SDK
4.Online Resources

A combination of these resources is the best bet in becoming skilled with Android Studio because each has its strong points and weak points. Some things covered in one book arent covered that well in others.
