TextureView

You need to initialize TextureView before opening a camera. TextureView is for displaying the image from camera on the device. However, you cannot use it unless the texture is ready, either because the screen is currently off or it is initializing.

You should check mTextureView.isAvailable() before opening your camera. Else you will mTextureView.setSurfaceTextureListener(). And open your camera in the callback method onSurfaceTextureListener.

Camera

Before opening your camera you should check for a camera permission first.
