实现纯语音互动

在开始通话时，音视频通话 UIKit 默认打开摄像头和麦克风，并将扬声器作为音频输出设备。

如需更改此默认配置，例如在开始通话时关闭摄像头，或者不使用扬声器（如果不使用扬声器，则将使用系统的默认音频输出设备，如听筒、耳机、蓝牙等），您可以修改以下配置：

turnOnCameraWhenJoining：通话开始时是否打开摄像头。true：打开（默认）。false：关闭。
turnOnMicrophoneWhenJoining：通话开始时是否打开麦克风。true：打开（默认）。false：关闭。
useSpeakerWhenJoining：通话开始时是否使用扬声器。true：使用扬声器（默认）。false：使用系统的默认音频输出设备，如听筒、耳机、蓝牙等。

以下是参考代码：

    ZegoUIKitPrebuiltCallFragment fragment = ZegoUIKitPrebuiltCallFragment
            .newInstance(appID, appSign, callID, userID, userName, config);

    getSupportFragmentManager()

            .replace(R.id.fragment_container, fragment)
            .commitNow();
