After downloading this source code. I tried running to test. But it's not running because of some errors. Please let me know how to fix it. Please refer below messages.

I have testing this app on my android phone. It's very nice to hear sound of nature and meditation. However the sound of audio is stopped without any kind of error and error log.

Please let me know why this kind of error is occurred.

Thanks in advance.
