Using setFlashMode - Android 2.2

Want to switch light on/off and not succeeding. Probably not getting the most from th documentation. In any event, this is what I have tried.

Amongst the imports I have

import android.hardware.Camera;

Within the body

Camera myCamera;
.......
myCamera = Camera.open();
.......
Camera.Parameters myCameraParameters = myCamera.getParameters();
myCameraParameters.setFlashMode(FLASH_MODE_TORCH);

The above line brings up an error 'FLASH_MODE_TORCH cannot be resolved to a variable' I am assuming that I am missing an import which defines FLASH_MODE_TORCH.

Anyine point me in the right direction?

IF I am missing an import, where should开发者_如何学Go I go in the documentation to find out what imports are needed for what statements, constants .....

I believe it should be Camera.Parameters.FLASH_MODE_TORCH. I was having some difficulty getting visibility to this parameter, but you should take a look at this questions They seem to have it figured out with an example.

This code might help comeone else

            Camera.Parameters myCameraParameters = myCamera.getParameters();
            String stringFlashMode;
            stringFlashMode = myCameraParameters.getFlashMode();
            if (stringFlashMode.equals("torch"))
                    myCameraParameters.setFlashMode("on"); // Light is set off, flash is set to normal 'on' mode
            else
                    myCameraParameters.setFlashMode("torch"); // This turns the light on
            myCamera.setParameters(myCameraParameters);
