关于android如何从a2dp重新路由音频

Question

I have a Samsung vibrant and I am connecting to to my car using bluetooth. In the samsung music app there is a button to route the audio to via bluetooth or via phone.

Anyone know how there were able create this functionality. I looked at the sdk and I see

ROUTE_BLUETOOTH_A2DP

This constant is deprecated. Do not set audio routing directly, use setSpeakerphoneOn(), setBluetoothScoOn() methods instead.

Routing audio output to bluetooth A2DP Constant Value: 16 (0x00000010)

but as you can see it is listed as "deprecated", i see the option for setBluetoothScoOn, but not an equivalent to for setting a2dp on.

My end goal would be to create a widget that allows me to turn on and off outing to the a2dp. So I can turn it on when I want to stream music and turn it off when I want to use navigator, but listen to music or the radio at the same time.

Here's what you are looking for: (not sure if this was available at the time of your question...)

setBluetoothA2dpOn();

But it's also deprecated.

My guess would be to use this instead:

audioManager.startBluetoothSco();
audioManager.setBluetoothScoOn(true);

And to stop routing:

audioManager.setBluetoothScoOn(false);
audioManager.stopBluetoothSco();

audioManager is a instance of the AudioManager.

Here's a reference to AudioManager: AudioManager

Hope this helps, cheers
