I am making an application that allows a user to record audio and save it somewhere in the SD card. I am using a MediaRecorder to do record the audio.
I am reusing some of the code from the androiddevblog website as it was recommended by another user on stackoverflow to check those tutorials.
My problem is whenever I click the button to record audio I get an error saying "Your Application has been forced to stop". I used the debugger to find out that it is because I have an illegalStateException on recorder.stop()
I am aware that nothing will get recorded based on my code. I want to first make sure the file gets created and saved.
I posted this question before, and solved my original problem but ran into this one after. So it may seem as a duplicate.
public class MyRecorderActivity extends Activity{
private static final String AUDIO_RECORDER_FOLDER = "AudioRecorder";
private static final String AUDIO_RECORDER_FILE_EXT_3GP = ".3gp"
private Button audio;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.questionandanswer);
....
....
audio = (Button) findViewById(R.id.audio_recordactivity);
audio.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
startRecording();
}
});
}
private String getFilename(){
String filepath = Environment.getExternalStorageDirectory().getPath();
File file = new File(filepath,AUDIO_RECORDER_FOLDER);
if(!file.exists()){
file.mkdirs();
}
return (file.getAbsolutePath()+ "/ " + System.currentTimeMillis() + AUDIO_RECORDER_FILE_EXT_3GP);
}
private void startRecording(){
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(getFilename());
try {
recorder.prepare();
recorder.start();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
recorder.stop();
recorder.reset();
recorder.release();
}
}
