Call recorder not working on 7.1.1. Others side pe

问题:

I have a call recording app. I am using CallRecordingservice to record voice through AudioSource.VOICE_COMMUNICATION in Android 8 (Oreo) , 6 and below working with some device but not in Android 7

I just found that something related to 7 that Android 7 has some security protocols and we have to overrite libmedia.so using NDK.

Note : I have tested 6.0 Devices and below versions also. For Nougat(7) device i have tested with Motorola G5 and Motorola G4 .

Same issues found here : Call Recording Issue 7.1.1

recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION);
recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
