Android UI Design

• Screen Design refers to the graphic design and layout of user interfaces on displays.

Android Operating System

• Android is a mobile operating system developed by Google for mobile phones and other devices like tablets.

Android Project Development Cycle

• The Android Project Development Cycle typically involves: Idea, Planning, Designing, Debugging, Prototyping, and Testing.

Android Intents

• Implicit Intents don't specify a component to start. Instead, they declare an action to perform, allowing components from other apps to handle it.

Android Manifest File

• The AndroidManifest.xml file describes the functionality and requirements of an Android application.

Drawable Resources - Level List

• Level List is an XML file that defines a Drawable managing multiple alternate Drawables, each assigned a maximum numerical value.
