Question

I just received a HTC Desire to test on. I noticed, that a mapView residuing in a frame smaller than a whole screen is not as sharp as a generic maps application. Is there any solution to this?

You should compile your application with API level 4 or higher and then set <supports-screens> in your AndroidManifest.xml like this:

  <supports-screens
  android:largeScreens="true"
  android:normalScreens="true"
  android:smallScreens="true"
  android:anyDensity="true"
  />

As described here: http://developer.android.com/guide/topics/manifest/supports-screens-element.html

This is because of two things:
1. Android 1.5 and lower doesn’t support multiscreen configurations.
2. There are no high density devices running even 1.6 – all above 2.0 (AFAIK)

If you want support 1.5 devices (12% of market for now) you may compile two separate versions of your app.
