Android: Filters out unsupported audio codecs(flac) on AudioRecorder app

Android MediaCodecList return all of supported media codes on the Android device.
AudioRecorder app show those codes on Audio Codec list.

eg. Sony xperia 5(A11) and Nokia 6.1(A10) returns:
Audio Codec:
 AAC
 FLAC
 Opus
File Container:
 Mpeg4Audio
 AAC
 FLAC

The AudioRecorder app use the MediaRecorder api for recording audio. 
The problem with this is that the MediaRecorder::setAudioEncoder ()
does not support the flac codec.
