Problem getting the NFC StampCollectionAdapter to increment, App recognizes Beacon contact but remains stuck at null. Symptom, when I touch Beacon activity goes to Chrome with a 404 error and doesn't launch the app but I do get (https://market.android.com/details?id=com.estimote.apps.maim.) project code is found at; https://github.com/Estimote/Android-SDK/tree/master/Examples/NFCStamps/app/src/main/java/com/estimote/nfcstamps.
Turns out that the Cloud's default AAR needs to be updated to match the build.gradle, applicationId, which in the Examples case is "com.estimote.nfcstamps". Once that is setup it should work as advertised.
