Re: [android-developers] Re: Is Android backwards compatible?

I think this has been brought up before and I've seen this as well. If you open the AVD manager that has the older platforms on it, you can manually start an emulator with one of them from there, then select the running emulator as your target when you do "Debug" or "Run".

Testing against older android versions in eclipse using AVDs is a
problem (hopefully I've missed something).

e.g.
I have AVDs created against 1.5, 1.6, and 2.0.
Using the New Android Project wizard create a project against 2.0 SDK.
Edit the manifest to set minSDKVersion=3, maxSDKVersion=5,
targetSDKVersion=5

Using RunAs|Run Configurations look in the Target tab. The only avd
available is 2.0. You cannot select an older SDK to test against.

(as I say, hopefully I have missed something)
