I have forked the https://github.com/layerhq/Atlas-Android-Messenger and added support for send and receive audio message from the mobile app.
Sending Audio Message:
AtlasMessageComposer.java handles below things,
* Recording audio message in .mp4
* Saving in SD card
* Displaying reording timer
* Send message via Layer client
Receiving Audio Message:
AudioCellFactory.java (which is new CellFactory to haldle audio message) handles below things,
* Rendering MediaPlayer with Seekbar in MessageListActivity if mime type meets audio type
* Downloading audio in SD card
* Playing audio via MediaPlayer
* Handles Paly/Pause
Notes:
* Reason for using .mp4 format is, FireFox not supporting .3gp files
* This modified app will create below folder structure in SD card root,
sd_card_root/Chat/Audio/Sent
Disclaimer:
I haven't added Runtime Permission for API level 23. So this app will crash if you run on API level >= 23. So feel free to add runtime Permission and give me a PR.
