I need a lightweight Android application that can reliably record both-party audio on voice calls. The main goal is personal archiving, so clarity of the captured sound on each side matters more to me than fancy UI touches. Target devices My day-to-day phones are Oppo, Vivo, Redmi and OnePlus models running recent Android builds (I can ship a test handset if that helps). The finished APK should install cleanly and work without root on those brands; if a minimal permissions tweak or foreground service is unavoidable, let me know early so I can approve it. Required feature set • Two-way call recording that survives the manufacturer’s call-recording blocks and new Android privacy changes. • An in-app call history log showing date, contact/number and recording length, with the ability to tap and play the file. Everything else—UI theme, storage location options, codec choice, etc.—is up to you as long as recordings remain accessible in standard .wav or .mp3 format. Deliverables & acceptance • Signed release APK plus full Android Studio / Kotlin or Java source. • Brief read-me explaining permissions requested and any special settings users must enable. • Successful test clips from each target brand proving both parties are audible. I’m happy to review alternative technical approaches—Accessibility API, VoIP capturing, native C++ libraries—whatever you believe will produce the cleanest dual-channel audio without root. Feel free to outline milestones and I’ll respond quickly.
