Android Project Structure

  • Gradle takes your Java code and XML layout and then uses the latest Android build tool to create the app package file, also known as an APK file. With Gradle you can customize your configurations to have development or production versions of the app that behave differently, or add dependencies for third-party libraries.

Your App has two main entities:

  1. What you want your app to do
  2. How you want your app to look Android Studio has a distinct way of managing these two entities. One is your JAVA files the other is your XML files.
Activities (Screens)
  • Java
    • Under the src/main/java directory
  • Resources
    • Drawable folders that hold images
    • Layout folder with XML that represents the screen designs
    • Menu folder with XML of the items that will appear on the Action Bar
    • Values folder with XML containing dimensions, strings, and styles
  • AndroidManifest.xml
    • Informs your system of the app's hardware and software requirements and contains your app's name,icon and version. Also filters the Intents coming in.
Testing
  • Can utilize a virtual device from the AVD manager
  • Actual Device
