24. APP STRUCTURE

25. RESOURCES
• Non-executable parts of an app
• Drawable - icons
• Layout - UI layout
• for landscape: create layout-land folder
• Menu - Menu items
• Values - for themes, and storing key-value pairs
• for other language: values-es

26. JAVA CODE
• Per Android Developer site, you need
JDK 7
• http://developer.android.com/sdk/
index.html
• resides in src > main > java
• MainActivity.java - default starting point

27. PACKAGES
• As your app gets bigger, you need to organize it
• That’s where packages come in
• make folders for modules
• adjust the “package” statement at the top of affected
java file
• Example (left): GDG app, from https://github.com/gdg-
x/frisbee/tree/develop/app/src/main/java/org/gdg/
frisbee/android
