Hi,

I'm trying to develop a call recording app.
This is the code to start recording:

<code>
try {
   MediaRecorder callRecorder = new MediaRecorder();
   callRecorder.setAudioSource(AudioSource.VOICE_CALL);
   callRecorder.setOutputFormat(MediaRecorder.OutputFormat.RAW_AMR);
   callRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
   callRecorder.setOutputFile(recordingPath);
   callRecorder.prepare();
   callRecorder.start();
}
catch (Exception e) {
   ....
}
</code>

I'm facing some problems testing in Galaxy S2 device.
It works great on Galaxy S+, and in other phone models it fails, but
at least an exception is raised ("start failed" message, not very
explanatory).
With Galaxy S2 this code hangs in "callRecorder.start();"
It never returns.

Has anybody found this problem?
Any idea about what can be wrong with this code?

Thanks
