[android-developers] Re: Screen size

Be sure you read this so you understand what you are doing:

http://developer.android.com/guide/practices/screens_support.html

Also, go ahead and ignore my point that you shouldn't do things based on the raw physical dimensions of the screen, but your app will break in the future when it is running on some device that has status-bar like UI elements along the side of the screen.  You can pretty much count on this happening, especially as larger screens like MIDs etc appear.

So, I solved it. I have problem with manifest.xml. When I don't use
android:targetSdkVersion="4" it resize for example QVGA from 240x320
to 320x427 and WVGA from 480x800 to 320x533. When I use
android:targetSdkVersion="4" everithing works good and

Display display = ((WindowManager) getSystemService
(Context.WINDOW_SERVICE)).getDefaultDisplay();

display.getWidth();
display.getHeight();

return me correct absolute size of the physical screen. QWGA 240x320
like in Table 1 on http://d.android.com/guide/practices/screens_support.html#range

Now I need density too, so I use

DisplayMetrics metrics = new DisplayMetrics();
                getWindowManager().getDefaultDisplay().getMetrics(metrics);
                metrics.densityDpi;

it returns 120, 160 and 240 int number.
