Open Source Flash Light one button, stable and fast. (no ads of course).

The important features are in AndroidManifest.xml :

And On :

cam = Camera.open();

Parameters p = cam.getParameters();

p.setFlashMode(Parameters.FLASH_MODE_TORCH);

cam.setParameters(p);

cam.startPreview();

Off :

cam.stopPreview();

cam.release();

cam = null;

Test if LED flash present in Android SmartPhone :

if (getPackageManager().hasSystemFeature(

PackageManager.FEATURE_CAMERA_FLASH))

Hope that helps.
