Android Application not running

Hi all,

I been working on a Android applicaiton, all works fine when i have my phone and/or tablet plugged in.

As soon as i change the build configuration from debug to release and upload the .apk to the developer console on google play, when i download and install the app it doesnt work all i get is a black screen and the app doesnt load.

Does anyone have any ideas ???

Thank you i advance.

The completely obvious questions first.

Are you using the right api?
What are the minimum and target SDKs in your manifest file?
Is your phone running a recent enough version of android?

If all of these are correct, can you debug on your phone rather than on a virtual device?
