Routing input to Bluetooth headset in android

Is it possible to r开发者_运维问答ecord an audio (not a phone call) using the bluetooth input and not the device microphone? I am able to playback whatever am saying through device's mic but not able to figure out how to use the bluetooth mic instead. Any assistance would be greatly appreciated.

(Edited) I got it working by using following two lines of code startBluetoothSco(); setBluetoothScoOn(true);

Got the bluetooth headset play back whatever am saying by using STREAM_VOICE_CALL in audioTrack initialization.
