Hi Maurice,
We've actually got a pretty similar setup for our SDK/APP, though while our
SDK is at 3.0-alpha7m the app is still sitting back at Gradle 1.3 which
makes things fun.
One thing I didn't see in your posted gradle files was a settings.gradle
file for the project which declares the sdk project and includes it in your
app project.
something like the following
include ':app', ':sdk', ':sdk-testing'
project(':sdk').projectDir = new File(settingsDir, '<path to sdk project>')
project(':sdk-testing').projectDir = new File(settingsDir, '<path to
sdk-testing project>')
Back when we had all our projects sitting at 1.3 this allowed us to rebuild
the sdk automatically when building the app.
Hope this helps,
Eric
