I successfully deployed a native android app. I'm using Sencha Touch 2.1 and sencha CMD v3. However, I ran into a problem. When I go to the app on my samsung galaxy tablet, I get an error message saying "Unfortunately, TouchWiz home has stopped". The app works. I can see it on my tablet and interact with it, but my tablet is really, really slow. When I press buttons on my tablet, it responds after a long while. When I uninstall my app, the tablet works normally. Is there something the app has access to that it shouldn't? Is there any measures I can take to prevent this? Thanks in advance.
