I have forked the and added support for send and receive audio message from the mobile app.
Sending Audio Message:
* Recording audio message in .mp4 * Saving in SD card * Displaying reording timer * Send message via Layer client
Receiving Audio Message:
* Rendering MediaPlayer with Seekbar in MessageListActivity if mime type meets audio type * Downloading audio in SD card * Playing audio via MediaPlayer * Handles Paly/Pause
* 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
