You might get confused when you see the path "Recorded file: /storage/emulated/0/Android/data/com.hyperionics.avar/files/Name of your file". Actually it's very simple. Just open your "My Files" >> then open "Device storage" >> from here it's normal as you saw in the picture. "Android folder" >> then "Data" >> "com.hyperionics.avar" >> "files" >> here you will find all of you saved/recorded files.
OK, you might think it's very simple. I know it's very simple for those who already know but some people still can get confused by this "/storage/emulated/0/" path, so I thought it would be better if I share it. Anyway this app is very useful for those who don't want to read long articles, you can just make this app read for you.
