Answer 1

Recording audio is possible at least in the standard 2.3.3 emulator on Windows 7; I have tried it and it works. However, the recorded audio did sound a bit weird (slow) in my case. I did not investigate the cause.

You need to add audio recording + playback support to the emulator (Android SDK and AVD manager -> Virtual devices -> Edit -> Hardware -> New). Then use the [MediaRecorder API][1] to record (MediaRecorder.AudioSource.MIC).

Code is:

fMediaRecorder= new MediaRecorder();
fMediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
fMediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
fMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

fMediaRecorder.setAudioChannels(1);
fMediaRecorder.setAudioSamplingRate(8000);

fMediaRecorder.setOutputFile(fTmpFile.getAbsolutePath());

fMediaRecorder.prepare();

fMediaRecorder.start();

You also need

< uses-permission android:name="android.permission.RECORD_AUDIO"/>

in your AndroidManifest.xml.

Works for me, but Audio IS distorted.
