Answer 1

Unfortunately RuntimeException for setParameters method is really generic and does not provide enough info of why it failed. Double check all parameters, one by one with the following command:

parameters.flatten();

Answer 2

try to change the code from :

myParameters.setPreviewSize(hei, wid);

to :

myParameters.setPreviewSize(myBestSize.width, myBestSize.height);

in public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) method
