Introduction to Android Open Source Project (AOSP)

The Android Open Source Project (AOSP) is the foundation of Google's Android operating system. It allows developers and manufacturers to create custom Android experiences tailored to specific devices. This project focuses on refining the Settings app for a device running Android 11, resolving upstream conflicts, enhancing features, and ensuring compatibility and performance.

Key Objectives

Resolve Conflicts:

Address inconsistencies and merge issues from upstream AOSP for compatibility with Android 11.

Fix UI/UX Bugs:

Improve functionality and design across dark and light modes.

Enhance Features:

Introduce support for Fingerprint on Display (FOD), color modes, and customizable themes.

Testing and Validation:

Conduct thorough testing to maintain stability and improve user experience.

Key Contributions and Fixes

1. Resolving Upstream Conflicts

• Screen-Off FOD Fix:
  Adjusted the default behavior of the Fingerprint on Display (FOD) gesture during screen-off to function seamlessly without requiring manual toggling. A patch ensures consistent performance even after resetting or reinstalling.

4. Code Cleanup and Performance Optimization

Removed redundant hardcoding and modernized layout XML files for better performance.
Streamlined color and theme logic for dynamic responsiveness and alignment with Android 11 APIs.
Challenges and Solutions

1. Conflict Management

Merging upstream AOSP updates introduced compatibility challenges with device-specific code. For instance, the Screen-Off FOD switch required careful adjustments to ensure compatibility without user intervention.

2. Testing and Debugging

Thorough testing was performed across multiple devices to identify and resolve edge cases, including handling mismatched color modes and ensuring stable integration of new features.

3. Maintaining Compatibility

Adapting to API changes in Android 11 required continuous updates to ensure compatibility with newer frameworks and device configurations.
