Setting the PTT button for an Android Bluetooth accessory

Starting with Android version 3.67, we've simplified the process to add accessory and device buttons. 

Adding a PTT button:

1. Using the manufacturer's instructions, pair your Bluetooth device to your Android phone
2. Tap open the App Menu (3 vertical dots)
3. Select Options
4. Select Push-to-talk buttons
5. Tap the Add (+) icon at bottom right corner
6. 
7. When prompted, press the button on the accessory to use as the PTT button
8. 
9. Test the button by using it to send a message to your Echo contact on Zello. 

IMPORTANT: Support for A2DP Bluetooth profile required by Zello. Compatible headsets are most reliably identified by A2DP support mentioned in headset specifications.
