how to force a photo into black and white

Question

So if the user takes a photo in color, I want to save it as a black and white picture.

Could someone help me?

Answer 1

cameraParams.getSupportedColorEffect(); and check if it contains Parameters.EFFECT_MONO then set

cameraParams.setColorEffect(android.hardware.Camera.Parameters.EFFECT_MONO);

mCamera.setParameters(cameraParams);
