If you're trying to record audio using AudioStreamer (via the internal Audio library), and you're getting exceptions when you try to start recording ("uninitialized AudioRecord object"), it may be because of permissions - specifically runtime permissions.
I downloaded Erel's AudioStreamer...
I want to develop my own voice recorder app (dictate app) .. The app should be able to rewind and playback the recorded audio and also work in overwrite or insert mode when recording. Can this be done with b4x?
