What is the proper way to set my drawable directories to support the new Dell Streak without losing support for older devices?

This seems to be a widespread problem.

I have the following drawable directories:

drwxr-xr-x  18 mike  staff   612 Feb  4 17:28 drawable/
drwxr-xr-x  51 mike  staff  1734 Feb  4 17:32 drawable-nodpi/
drwxr-xr-x  44 mike  staff  1496 Feb  4 17:30 drawable-normal-mdpi/

My xml drawable resources are in drawable. My resources intended for the large-mdpi (Dell Streak) and normal-hdpi (Droid, Nexus, Incredible, etc.) are all in drawable-nodpi. My resources for normal-mdpi (older phones like the G1) are in drawable-normal-mdpi.

Unfortunately, the normal-hdpi phones like the Droid are pulling their resources from drawable-normal-mdpi instead of from drawable-nodpi. This is likely because of the rules in How Android Finds the Best-matching Resource.

So the question is, how do I provide support for large-mdpi devices like the Streak along with normal-hdpi devices like the Droid, as well as normal-mdpi devices like the G1?

The simplest solution would probably be to make two copies of my large resources, one in normal-hdpi for the droid and one in large-mdpi for the streak, but i'd like to avoid duplicating all of these resources.

Update

Per Mayra's suggestion, I could make an alias for every resource. However, there are a lot of resources I'd have to make aliases for, which would make maintenance a nightmare going forwa开发者_开发问答rd, so I'm hoping for another solution.

Rename your "drawable-nodpi" to "drawable-nodpi-800x480" (the nodpi needs to be in there, or it wont work!) and rename "drawable-normal-mdpi" to "drawable-480x320".

You can use an alias resource to provide a pointer to the resource without copying it. See Alias Resources

Have you tried putting the HDPI resources in just the drawable folder and not drawable-nodpi?

I asked the same question 2 days before you and the closest thing to a solution was using the alias resource (via Mayra). I ended up writing a python script to handle this for me. Its a really bad work around and I wish I had enough determination to create a more fool proof solution.

Just for reference, the shared resources belong in a nodpi folder so they aren't scaled by android.

Check this guide: http://developer.android.com/guide/practices/screens_support.html

Basically, you should put your drawables in drawable-mdpi, drawable-hdpi, etc. and your layout files in layout-small, layout-medium, etc. directories. So, layouts should be screen size dependent and drawables should be screen density dependent.
