title: Android app won't open after i install. But it can run in emulator
body: <p>I have exported my app from eclipse and installed it on my phone. After installation, I click open from package installer, but the installer force close. Afterwards, when I tried to launch the app, nothing happen after I click it. I click the app in app drawer but it return to home screen instead.</p>
  
  <p>I am able to run in emulator and in debug mode when I connect my device via usb, but not when I export the apk to install.</p>
  
  <p>Note that this is not the first app that I exported to install. Previous apps are working fine.</p>
