My application worked yesterday, I cant figure out why it stopped working. The only thing I tried doing was to create a signed apk. to do this I had to create a new Google maps key and place it into the manifest file. I done this following the Google developers tutorial. But now when I try to run the app it start up, I click a button and it force closes.

This is the error log:

This is the corresponding xml file:

    android:background="#000">

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
