Accessibility-ready sound recorder and player working with gestures. There is no need of settings menu or Talk-back feature to use it. There are two key concepts, "Files and one layer of Folders" . 

Quick manual:
- DoubleTab: Start recording
- SingleTab: Stop or Mute recording and playing
- Swipe left/right: File navigation.
- Swipe left/right and hold: FF and Fast rewind
- Swipe Up/Down: Folder navigation
- Swipe Up/Down and hold: Fast folder navigation
- Longpress: Speak file/folder information
- Delete: 4-fingers Left to Right swipe, move the target file to .Trash folder
- Target files to read:
MediaScanner DB files can be found under the folder of "All-Music-By-MediaScanner".
{sdcard}/Music, e.g. /storage/emulated/0/Music in case of GS5
{sdcard}/{Application Data}/Music. Recorded files are going under here with name of Month-Year e.g. /storage/extSdCard/Android/data/com.jonlee.android.SJplayer/files/Music/July-2014/

Target user: There is only one user, SangJoon Lee who is 10 years old boy who is blind and my son. 

Goals by this app:
- Sangjoon who is a blind can 'record', 'play back' and 'navigate folder/files' by himself.
- Better and cheaper solution than Victor reader
- Ultimately, it will help him to learn music and any critical events in his life

Problem to solve by this project:
- Professional recorders does not support many number of files in a directory by OS limitation. For example, SJ has more than 30K recoding files so far and there is no way to store and play back them. 
- Existing recorder apps are not ACCESSIBLE by Sangjoon. Too much complicated or no need Full feature of Talkback at this time. 
- Button based UI does not work for him by observation.
- IMMERSIVE MODE is required as any SW key on screen distracts its UX
- MediaScanner is not best for supporting mass number of recorded file. 
- Recording anytime and anywhere.
- So far, he has 20K+ audio files recorded, device needs to support the maximum size of SD card in market.
