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:
