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

I found the answer to this on stack overflow here: getting the screen density programmatically in android?

Use getResources().getDisplayMetrics().density or context.getResources().getDisplayMetrics().density to get:

0.75 - ldpi

1.0 - mdpi

1.5 - hdpi

2.0 - xhdpi

3.0 - xxhdpi

4.0 - xxxhdp

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?
