Android: Changing entry point activity to app messes up app update
<p>This is the second time this has happened to me now. I changed the starting activity of my app, and put out an update, and now the icon on people's phone will not open my app. The only way they can open it is through the downloads section of their Android Market app, or if they uninstall and reinstall the app, causing them to lose ALL their data.</p>

<p>I have no problem with updates on my N1, but every other Android phone has a problem with this. Why?</p>
