Using Mac OSX 10.8.3 and Eclipse ADT with Android SDK to follow the Google Cloud Platform tutorial (https://developers.google.com/cloud/samples/mbs/getting_started). When the client app is deployed to a Nexus 4 (4.2.2), the app is started, it fails with the error "Unfortunately, CloudBackendAndroidClient has stopped." In Eclipse LogCat I see the errors as copied below. Any hints? As the tutorial mentions, this code is supposed to just work with only one line in Consts.java file being edited.
