I am trying to record audio but the start()
method of MediaRecorder
class throws an IllegalStateException
.
I use the following code:
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile("/sdcard/");
try {
recorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.i("Try","Exception");
recorder.start();
And following permission
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Vijay, recorder.setOutputFile("/sdcard/"); is setting a directory, not a file. Replace that with:
mFileName = Environment.getExternalStorageDirectory().getAbsolutePath();
mFileName += "/youraudiofile.3gp";
Using "/sdcard" hard codes a path which is fragile, so use the above
Also, for this to work you must add
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
to your AndroidManifext.xml
