Pay attention to these lines, this is the cause of your error:

java.lang.RuntimeException: Unable to start service com.topgamesandapps.audiorecorder.RecordingService@1cedefa with Intent { cmp=com.topgamesandapps.audiorecorder/.RecordingService }: java.lang.RuntimeException: setAudioSource failed.

Caused by: java.lang.RuntimeException: setAudioSource failed.

Investigate the stack trace carefully, it usually contains enough information to pinpoint an exception cause.
