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.

Hello, I will build a lightweight Android call recorder that captures both-party audio on Oppo, Vivo, Redmi, and OnePlus devices — delivering a signed APK, full Kotlin source, and a tested read-me. For dual-channel recording on recent Android builds, I will use the Accessibility Service approach paired with a native C++ audio capture layer via AudioRecord. This combination bypasses most OEM call-recording blocks without root — and encoding to MP3 with a 128kbps bitrate keeps file sizes small while preserving voice clarity on both sides. Questions: 1) Which specific Android versions are your test handsets running — Android 13, 14, or 15? 2) Do you need automatic recording on every call, or a manual toggle per call? Looking forward to your response. Best regards, Kamran

Hi there, I have read your project requirement. You need a lightweight Android application that can record two-way call audio (both sides) with high clarity, work reliably across devices like Oppo, Vivo, Redmi, and OnePlus without root, and include a simple call history with playback support. The app should handle modern Android restrictions, store recordings in standard formats (WAV/MP3), and remain stable and easy to use. We can build the most reliable solution possible using optimized recording methods, foreground services, and device-specific handling to maximize compatibility and audio quality, along with a clean and simple interface. A few questions: ============== Do you want automatic call recording or manual control (start/stop)? Is speaker-based fallback acceptable if direct call recording is restricted on some devices? Should recordings be stored only locally or include optional backup (future scope)? Do you need features like search, filter, or tagging in call history? Best Regards, Srashtasoft Team
