Android Audiobook App Development
Budget: ₹12,500 – ₹37,500 INR
I’m ready to commission an Android-only audiobook application and need an experienced mobile developer to take it from concept to Google Play release. At its heart, the app must stream and locally cache audiobooks, let listeners drop unlimited bookmarks while they listen, and handle one-tap downloads for fully offline playback.
Monetisation is essential: new titles will be sold individually, so please wire the catalogue to Google Play Billing for in-app purchases. Authentication will be straightforward email-and-password login—either a lightweight back-end you spin up or a Firebase Auth integration works for me so long as it’s secure and quick for the user.
Core flow I have in mind
• Launch ➜ user signs up or logs in
• Library screen lists available audiobooks (free and paid)
• Detail screen shows cover art, description, price, and a Download / Buy button
• Playback screen uses a robust player (ExoPlayer or similar) with 15-sec skip, variable speed, and a Bookmark button that stores position even if the user re-installs the app
• Local file management automatically deletes finished books after X days unless the listener chooses to keep them
Deliverables
1. Production-ready Android Studio project with clean, well-commented Kotlin (Java acceptable if you prefer)
2. Working APK for testing plus signed AAB for Play-Store submission
3. Integration with Google Play Billing (test product IDs)
4. Secure email/password login backed by Firebase or your proposed solution
5. Brief README covering build steps, third-party libraries, and server endpoints if any
Acceptance criteria
• Seamless playback and bookmarking survive app restarts and device reboots
• Downloaded titles play smoothly in Airplane Mode
• Purchase flow passes Google’s test cards without error
• Code compiles on the latest stable Android Studio without warnings
If you have previous work with media apps, streaming, or Play Billing, please mention it and share a link or APK. Looking forward to collaborating and getting this audiobook experience into listeners’ hands.
