Question

Answer 1

First you get supported flash modes:

camera = Camera.open(i);    // Introduced in API level 9
parameters = camera.getParameters();
String[] flashModes = parameters.getSupportedFlashModes();

And then you check if this array contains the correct constants like: "auto", "on", "off".
