Android recording call using NDK

Question

I was very tired when making a call recording application for Android. I know the official Android SDK has not allowed using VOICE_CALL. So my recording is based entirely on the MIC source. I tried the Android NDK but I also fell into a deadlock. Someone, please give me away. If you have the source code, it's great. Thank you very much!

Answer 1

Android has officially blocked the SDK method since Marshmallow. After that a work around was introduced with the NDK to solve the problem. This seemed to work in android 6, 7 and 8. The NDK based approach is also blocked in Pie. So technically it is impossible to record calls. Source

Answer 2

Record a call in Android could be a strenuous work, this because not all Android version support the call recording.
