Android problem..

I want to Build and Run my game on Android Samsung Galaxy S and when I do so I get the following error: KeyNotFoundException: The given key was not present in the dictionary.

The problem is regarding the .apk file signature.

What is the signature?: Sign your app  |  Android Studio  |  Android Developers

You will need to enter it into the Keystore password via the player settings.

You can avoid the signature issue by checking the “development build” box.
