[android-developers] Re: getDensity returning 0 in attempt to create pixel density independant controls

Don't use the Canvas' density, use the Display's.

i'm attempting to draw pixel density and resolution independent controls to the screen for my game.

 

 if I use screenWidth in declaring the size, the control's size will vary with resolution. if I just use a certain number of pixels, the control size will vary with pixel density.

 

assume i need canvas.getDensity(), as there is no action like

 

canvas.drawCircle(cx,cy,60di,paint). //di: density independent pixel

canvas.getDensity() is returning 0, however. I saw on a different post a suggestion of disabling the GPU to fix this. I don't want to disable the GPU on my user's phones' though, even if I knew how. how do I get around this?
