I am trying to send some data to Azure from my Android app. I am using the example provided by Azure when setting up a Mobile Service. I have no errors in the code but when I try and load an activity on a button click the app crashes. The activity I am trying to load has the Azure interaction code on the onCreate method.
UPDATE
This works on other android devices but when I try and run it on a Samsung Galaxy S3 Mini runnning Android version 4.1.2 it crashes.
