Wow this completely explains what happened to me after updating to the 2.2 SDK. The documentation goes into detail about how the current environment picks hdpi or ldpi or what have you, but doesn't explain how previous versions operate at all. From a beginner's mindset, it seems to follow that since 1.5 wasn't dpi aware that it wouldn't read resources out of any folder containing a dpi setting (even mdpi). But this is not the case and it took me trial and error to understand the way it works. It is also not clearly mentioned that the solution is to do a hdpi-v4 and ldpi-v4 directory and an mdpi directory. In fact this was specifically not the solution recommended at Google IO a couple of days ago.
So in conclusion, thanks for finally revealing how this works now (and has worked in previous androids) Dianne, and I would gladly write up a documentation patch but I don't think the d.android.com articles are in gerrit right? -Eric On Jun 8, 8:57 pm, Dianne Hackborn <hack...@android.com> wrote: > Um, no, you should use -hdpi-v4 so that v3 of the platform does not see the > hdpi resource (which it does not understand) as a possibility. > > Also as of 2.2 aapt will automatically include the appropriate minimum > version for new configurations, so that older platforms do not see them. > Though I notice that it uses -v4 for a resource that has ANY density > specified, so if you don't have default resources for images you may break > on 1.5.
