I’m using android version 2.2 and I cant find android.bluetooth.IBluetoothA2dp in the bluetooth sub-package android.bluetooth.
Do I have to upgrade to a higher version for this file to be available. Or what else should I do so I could be able to implement this interface to use it in my project?
I’m not sure why you need
IBluetoothA2dpand not theBluetoothA2dp. But theIBluetoothA2dpinterface is a hidden interface (see here). At least up to Android 3.0 (not including).As for
BluetoothA2dpclass it was publicly introduced in API Level 11 (Honeycomb, Android 3.0). It was first introduced in Android as earlier as API Level 3 and marked as hidden. Then it was dramatically changed in API Level 5 at still was marked as hidden. And officially released only in API Level 11.You can use reflection to access that class on earlier platforms, but that’s a tricky and not recommended way.
