I am trying to build a test app with Mobile SDK in eclipse, I've managed all the steps and I don't see errors in the project. But when I try to run my application on a virtual device, I get this error:

04-07 12:11:53.251: I/dalvikvm(933): Failed resolving Lcom/fnr/test/KeyImpl; interface 11 'Lcom/salesforce/androidsdk/app/SalesforceSDKManager$KeyInterface;'

In Eclipse I have my test project, a project with SaesforceSDK and a project with SmartStore. The dependencies are marked via Properties -> Android -> Library. For what I see in my test project there is a KeyImpl.java file indeed in the package.

Have you faced this problem? Thanks in advance
