Questions:

There are some screen resolutions already defined in Android.
They are:

  • QVGA (240×320, low density, small screen)
  • WQVGA (240×400, low density, normal screen)
  • FWQVGA (240×432, low density, normal screen)
  • HVGA (320×480, medium density, normal screen)
  • WVGA800 (480×800, high density, normal screen)
  • WVGA854 (480×854 high density, normal screen)

How do I know which type my device screen resolution is?

How to&Answers:

Use DisplayMetrics to get screen info from your device.

Sample code:

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

final int height = dm.heightPixels;
final int width = dm.widthPixels;

Answer:

Have you tried to search the specifications of your device? i.e. from Wikipedia’s Nexus One article, you can find Nexus one screen resolution:

Display 480 x 800 px (PenTile RGBG), 3.7 in (94 mm), 254 ppi, 3:5 aspect ratio, WVGA, 24-bit color AMOLED with 100,000:1 contrast ratio and 1 ms response rate

That’s a starting point…
