It would be easier if I had your computer to tell you whats wrong sorry :/.. Maybe try to save and create a new project and run something simple such as the fancy "Hello World" and see if it works. If that does not work you could save all your code to a text document and just redownload Android Studio. Sorry if I am not much of a help.

Put 3 on the top and bottom line so its easier to read the errors or code.. Put 3 and click enter.. paste the errors or code.. enter and 3 more `

Are there any errors in your code? Refresh the app (Top left next to save) and see if that works.
