是否有可能知道哪些相机当前正在使用android？

Question

在我的应用程序中，我想知道相机应用程序是否开启以及相机的类型（前置相机还是后置）？

Answer 1

Camera类可能会解决您的问题。执行getCameraInfo获取信息，然后使用CameraInfo。它有两个常量：

int CAMERA_FACING_BACK The facing of the camera is opposite to that of the screen. 

int CAMERA_FACING_FRONT The facing of the camera is the same as that of the screen. 

Answer 2

支票

Camera.CameraInfo.CAMERA_FACING_BACK; 

OR

Camera.CameraInfo.CAMERA_FACING_FRONT;
