[kailash09dabhi]

pls show your wavsetupRecorder() method. It should be some illegal parameter not sure of though

[nzala]

private void wavsetupRecorder() {
        recorder = OmRecorder.wav(
                new PullTransport.Default(wavAudioSourcemic(), new PullTransport.OnAudioChunkPulledListener() {
                    @Override
                    public void onAudioChunkPulled(final AudioChunk audioChunk) {
                        progressbar.setProgress((int) (audioChunk.maxAmplitude()));
                    }
                }), wavfile());
    }

    private AudioSource wavAudioSourcemic() {
        smart = new AudioSource.Smart(MediaRecorder.AudioSource.MIC, AudioFormat.ENCODING_PCM_16BIT,
                AudioFormat.CHANNEL_IN_MONO, frequency);
        return smart;
    }

file is read-Owner, Group
write-Owner only
hw make
read and write-Owner, Group, Others

[kailash09dabhi]

Are you sure you have write permission to record & access external storage in manifest?

[nzala]

yes

[nzala]

hw make
read and write-Owner, Group, Others

[kailash09dabhi]

i am saying about permission in manifest.. android.permission.WRITE_EXTERNAl_STORAGE

[nzala]

yes i have
u need call recordInstance.release()? in https://github.com/kailash09dabhi/OmRecorder/blob/master/om-recorder/src/main/java/omrecorder/AbstractRecorder.java

[nzala]

hw make wav file
read and write-Owner, Group, Others

[kailash09dabhi]

This issue only happens due to permission.. See you are also requesting on runtime as from android 6.0 onwards we need to request permission on runtime.

[nzala]

i slved i called recordInstance.release()
but hw make wav file
read and write-Owner, Group, Others
i have made all permission on runtime.

[kailash09dabhi]

I am glad you solved it you can explain more here how you solved to help other users.
If you want to release the audio source you can do by simply like this:

 pulltransport.audioSource().release();

[nzala]

yes
pulltransport.audioSource().release();
but hw make wav file
read and write-Owner, Group, Others
i have made all permission on runtime.

[nzala]

jus add

if (recorder == null)
            return;
        if (recorder != null) {
            recorder.stopRecording();
            pulltransport.audioSource().release();
            recorder = null;
        }

[nzala]

make wav file
read and write-Owner, Group, Others
i have made all permission on runtime.

Hey @nzala , how you call pulltransport.audioSource().release(); in your project? cause I call event call for audioSource() to pullTransport.. can you give me some hint?
