R.java Is Missing From My Project And Will Not Regenerate

I've began making a new project and just as I was linking my buttons to the java I noticed my R would not resolve and come to find out that my R.java file is not there. I've looked

Solution 1:

You probably have an error in an xml file. R.java will not be generated if there are xml errors. Look through you Manifest.xml and all your layout, values, and any other xml files in res.

Once you have found and fixed the error, clean the project.

Solution 2:

You probably have problem in resource folder, first solve that error.numeric name of image can generate errors.After solving the errors just clean your project or Build your Project. R.java build again if error is fixed.
