I have written this code for recording Calls. It works fine in Android 2.1. In Android 2.2, it creates an output file with 0 bytes.
How I can solve this?
MediaRecorder _recorder = new MediaRecorder();
public void start() throws IOException {
try {
String state = android.os.Environment.getExternalStorageState();
if (!state.equals(android.os.Environment.MEDIA_MOUNTED)) {
throw new IOException("SD Card is not mounted. It is " + state
+ ".");
}
// make sure the directory we plan to store the recording in exists
File directory = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/sam.wav").getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
throw new IOException("Path to file could not be created.");
}
_recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL );
_recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
_recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
setOutputFile(Environment.getExternalStorageDirectory().getAbsolutePath()
+ "/test.wav");
_recorder.prepare();
_recorder.start();
} catch (Exception e) {
e.printStackTrace();
}
}

Use this snippet
_recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_DOWNLINK
| MediaRecorder.AudioSource.VOICE_UPLINK );
instead of
_recorder.setAudioSource(android.media.MediaRecorder.AudioSource.VOICE_CALL);

Call recording only works on some Android phones. It might work on one phone running 2.1, but not on a different model running 2.2. Although the API will compile and run on all architectures, some devices have disabled this feature in the hardware.
See How can I record voice and record Call in Android? for more details.
