/**
 * This factory allows a HAL implementation to be split into multiple
 * independent providers.
 *
 * When the Bluetooth stack is ready to create an audio session, it must first
 * obtain the IBluetoothAudioProvider for that session type by calling
 * openProvider().
 *
 * Note: For HIDL APIs with a "generates" statement, the callback parameter used
 * for return value must be invoked synchronously before the API call returns.
