Hi,all.
The app I wrote doesn't run correctly on the device.Could someone give
me a suggestion that how to solution this problem.
The code is below.
--------------------------------------------------------------------------
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile("/sdcard/test.amr");
try {
recorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
Log.e(Tag, "IllegalStateException");
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
Log.e(Tag, "IOException");
e.printStackTrace();
}
recorder.start();
------------------------------------------------------------------------------------
The log is below.
