Job Description

We are looking for a highly skilled Native Android (Java) developer to fix critical bugs in our existing Taxi App. This is a test project: successful completion can lead to long-term monthly maintenance and support opportunities.

Project Context

  • App Type: Native Android (Legacy Java). Not Flutter.
  • Backend: PHP Core + Node.js (SocketCluster.io) for real-time tracking.
  • Current Status: Updated to target Android 15 (API 35).

Immediate Issues (Android 15 Compliance)

Due to stricter permissions in Android 15, the following features are broken:

  1. Firebase Chat – Messages fail to deliver/sync in real-time (likely background restriction issues).
  2. Sinch Voice Calls – In-app calls fail to connect or crash (likely Foreground Service permission issues).
  3. Android 15 Play Store Compliance – Ensure 16KB Page Alignment support.

Requirements

  • Expert in Legacy Java Android debugging.
  • Experience with SocketCluster or Socket.io integrations.
  • Deep knowledge of Android 14/15 background and foreground permissions.
  • Ability to deliver a production-ready APK/AAB with all features working.

Deliverables

  • Diagnosis of the root cause for chat and voice call issues.
  • Fully functional production-ready APK/AAB.
  • Documentation of fixes applied.
