How to stream audio from one Android device to another Android device Via Bluetooth?

Question

Is it possible to stream audio over bluetooth? During my research I found that is it only possible using A2DP(Advanced Audio Distribution Profile). And does every android device support A2DP? If not, is it possible to stream audio between two android devices using bluetooth? Please help me understand this.

I've looked through the following links:

• Receive audio via Bluetooth in Android,
• Google confirms bluetooth audio streaming fix for next version of Android 4.2
• How can I stream audio from another device via Bluetooth?

Is it possible to stream audio over Bluetooth?

Below sort of thread says its possibility that streaming audio over Bluetooth is possible between devices but there was question mark on its success rates till Google official announced that We have fixed the a2dp streaming stutter problem on N7. The next release should have the fix. Sorry about the problem.

And does every android device support A2DP?

Support compatibility is mention on Android developers site that its added from API Level-11 with appropriate features. But I came across XDA tread where OP mention problem in Android 2.1,means its also support in previous api levels but OP facing issues.

Hope it make sense to understand and I would like to recommend to refer XDA forum to get more information about A2DP compatibility and its sucess.
