Android: Check whether camera supports auto-focus?

Question

For the Android API version 2.1 and higher, we can use context:

getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_AUTOFOCUS)

Answer 1

There are a number of methods of the Camera.Parameters class added in API Level 5 (I believe that maps to Android 2.0) that will return a list of supported features. Call getSupportedFocusModes on the Camera.Parameters object retrieved from camera.getParameters()
