DisplayMetrics issue on Android1.6 SDK

 I got a issue with DisplayMetrics.

  DisplayMetrics dm = new DisplayMetrics();
  getWindowManager().getDefaultDisplay().getMetrics(dm);
  Log.d("TEST", dm.widthPixels + "x" + dm.heightPixels);


If I do not specify the <uses-sdk android:minSdkVersion="4" /> or
<supports-screens android:anyDensity="true"></supports-screens>, then
the value of dm.widthPixels and heightPixels is wrong on QVGA and WVGA
screen. e.g. on QVGA, the return value is 320x427.

If this is a bug on Android1.6 SDK?

 That is intentional.  If you haven't said you support other densities than
the framework runs you in a compatibility mode to make it look like you are
on a medium density device.  By saying that you work with SDK 4, you are
also implying that you understand how to deal with densities.
