96 dpi is certainly wrong for Moto Droid / Milestone.
Try using Canvas.getDensity(). -- Kosyta 06.08.2010 5:14, sdphil пишет:

Normally, I could do something like this: DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics( metrics ); Then use metrics.widthPixels and metrics.heightPixels. Now that I know the width and height in pixels, I should be able to calculate size in inches if I know the density. Easy enough, metrics.xdpi and metrics.ydpi. Then screen dimension in inches should be: widthInInches = metrics.widthPixels / metrics.xdpi; heightInInches = metrics.heightPixels / metrics.ydpi; Seems simple enough except that it doesn't work. On a Motorola Droid, the system reports back: xdpi and ydpi as 96 (which cannot be true). And the screen resolution as: 480 x 854. Which results in a width of 5" x 8.9" -- which as I'm holding this in my hand right now, I must say - cannot be correct. Any ideas on how to accurately calculate this?
