Android card guessing

Hi, I tried to build and run from the following sample but I'm getting couple error: 1- Error running MainActivity: The activity 'MainActivity' is not declared in AndroidManifest.xml 2- Error:(553, 69) String types not allowed (at 'activity_horizontal_margin' with value ''). 3- Error:Execution failed for task ':app:processDebugResources'.
> Failed to execute aapt


Can somebody tell me what I'm missing?
