Multiple icon images in Honeycomb

Question

I'm trying to change my app icon to make it match the blue of Honeycomb but maintain the green icons for previous Android versions. I've come across a problem where if I put the blue 72x72 icon in drawable-xlarge, it uses it correctly in the launcher but it also uses that for the ActionBar. 72x72 is so large, it extends beyond the ActionBar top & bottom.

My res directory is as follows:

drawable - images for ldpi & mdpi screens (48x48)

drawable-hdpi - for hdpi screens (72x72)

drawable-xlarge - just images for tablets

How can I correctly organise the blue icons so 72x72 is used for the launcher and 48x48 is used for the ActionBar?

Answer 1

Honeycomb's launcher will use available hdpi drawables as higher-res mipmaps on mdpi devices. mdpi icons should still be 48x48. If you want to provide resources specific to xlarge screens you should provide versions in drawable-xlarge-mdpi, drawable-xlarge-hdpi, etc.

However, if your goal is to provide icons that match the styling in Android 3.0 you might want to use v11 (API level 11) as your qualifier instead of xlarge. (e.g. drawable-mdpi-v11, drawable-hdpi-v11)

API level version qualifiers in your resource organization can be useful in other circumstances where system styling changed too, such as the notification icon style changes in 2.3.
