launcher icon resizing

Question

I am trying to make my MediaShortcut app ( source ) create launcher icons whose size depends on the density of the screen. The image is retreived from android.provider.MediaStore.Images.Thumbnails .getThumbnail(getContentResolver(), "imageid"), android.provider.MediaStore.Images.Thumbnails.MICRO_KIND, null)

So first i get the screen's density using http://developer.android.com/reference/android/util/DisplayMetrics.html and then resize the image according to this table http://developer.android.com/guide/practices/ui_guidelines/icon_design.html

This seems to work fine on most of my devices but on my Asus slider (and a friends transformer) the icon is significantly smaller than the other icons on the home screen. on other devices i have noticed the icon is too big and only part of it is shown.

Does anybody have any idea why this could be? Thanks!

Answer 1

since api 11 the launcher icon size is implementation specific. i home homescreen apps honor this...

http://developer.android.com/reference/android/app/ActivityManager.html#getLauncherLargeIconDensity() and http://developer.android.com/reference/android/app/ActivityManager.html#getLauncherLargeIconSize()
