You should be able to check whether the flash is available by checking system features:

boolean hasFlash = this.getPackageManager()
                       .hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH);

(provided you are in an Activity). If not, than use some sort of context in place of this.

P.S. Note that this information is quite easy to find if you actually try searching for it.
