hi I tried writing a java wrapper class that interfaces the native library using JNI. But i am getting RECORD_AUDIO permission denial from the emulator. I have added RECORD _AUDIO permission in the Android manifest.
My application doesnt use mediarecorder to record but talks to the native interface audiorecord for the recording using JNI. Am i missing something?
