SJ Music player for Blind(Accessibility ready)

Gravador de som e leitor para cegos, funções completas funcionam com gestos.

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.
