I want my Android application to support 2.1 (Eclair), but I also want it to support installation to sd-card for 2.2 (and later) users.
I’m using MOTODEV, and I created a new 2.1 project. I tried adding android:installLocation="preferExternal" to my manifest file, but it doesn’t work because it’s not supported in 2.1. How can i make my application support SD-installation and at the same time support 2.1?

EDIT: I see I can use android:installLocation="preferExternal" even for 2.1 and older builds according to http://developer.android.com/guide/appendix/install-location.html#Compatiblity. The trick is, as CommonsWare stated below, to change the build target to 2.2.

The problem now is that Eclipse/Motodev won’t let me run or debug on virtual devices that are older than the build. It simply doesn’t list the device. I tried tricking it by changing the build target, choosing an older device in run/debug configurations, and then changing build target back, but I just got the following message in the console:
