原标题:How to determine BT headset type (SCO or A2DP) in Android SDK?

I have a broadcast receiver in my app that logs every connection of a BT device by tracking the android.bluetooth.device.action.ACL_CONNECTED broadcast. But I need to know if the BT device isa headset, and more importantly, if it s an SCO or an A2DP headset. I can find out what services the connected device supports using BluetoothClass.Service, but I don t know which services are supposed to correspong to each type of headset. Here are the ones listed:

AUDIO 
CAPTURE
INFORMATION 
LIMITED_DISCOVERABILITY 
NETWORKING 
OBJECT_TRANSFER 
POSITIONING 
RENDER 
TELEPHONY

谁能告诉我,其中哪一类是头盔(头盔、手无寸或A2DP)?

问题回答

You can use BluetoothProfile.ServiceListener and listen for onServiceConnetced and you will get notifications for A2DP or SCO connected. See here
