Android App Development Essentials
What’s Inside an APK File?
Android SDK tools compile your Java source files into .dex files and then zip them together with project resources (images, layouts, etc.) and the manifest file into an APK. You need to build the .apk from Android Studio at least once to see the apk folder on your laptop. Unzip any Android .apk, and you’ll see these files inside:
YourProject/app/build/outputs/apk- Resource: layouts, icons, images, animations, strings
- Manifest: application-wide configuration (components, permissions)

Binary Trees
First Element
The first() method returns the first element in the binary tree by recursively traversing the left subtree until it reaches the leftmost node.
Last Element
The last() method returns the last element in the binary tree by iteratively traversing the right subtree until it reaches the rightmost node.
Add Element
The add(E item) method adds an element to the binary tree while maintaining its sorted order. It first checks if the element already exists and returns false if it does.
Signal Modulation and Multiplexing Techniques
Signal: An electromagnetic field whose variations convey information. Signals can be analog (continuous) or digital (discrete sequences). Modulation: The process of altering a periodic carrier signal (constant amplitude and frequency) to transmit information. Modulation types include Amplitude Modulation (carrier amplitude changes with the modulating signal), Frequency Modulation (carrier frequency changes with the modulating signal), and Phase Modulation (carrier phase changes with the modulating
