Fix Android App Browser Proxy Issue

I have an Android app that is intended to open the default browser with a proxy, but it's not functioning as expected. I need an experienced developer to help troubleshoot and fix the issue via a live screen share session.

Ideal skills include:
- Proficiency in Android app development
- Experience with network programming and proxy configuration
- Strong problem-solving skills
- Ability to communicate effectively during live troubleshooting sessions

Key issues to address:
- The app needs to open the default browser with the specified proxy (username and password)
- Troubleshooting and fixing any other issues with the app

Please only apply if you can assist in real-time via screen share. Thank you!
