Android front camera

Question

I need ONE function to check if front camera exist, and if so - show preview. I found a few links, but each of them talk about a specific device:

• How do I open the "front camera" on the Android platform?
• http://developer.android.com/reference/android/hardware/Camera.html#open(int
• Front-facing camera on LG Optimus 2X Speed
• How to use Front Facing Camera on Samsung Galaxy S

Can anyone provide a generic code for this? Or maybe a combined code that will work with all devices?

Answer 1

For APIs >=9, you can use the Camera class: http://developer.android.com/reference/android/hardware/Camera.html to see if it has more than one camera, and query the CameraInfo

• getNumberOfCameras

• getCameraInfo:

http://developer.android.com/reference/android/hardware/Camera.CameraInfo.html

Constants

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.

For APIs >=5, an option is to read public List<Camera.Size> getSupportedPictureSizes (). Front facing cameras will usually have much lower max resolution than back cameras.
