After upgrading to Android ADT version 22 and cleaning my project, the R.java files went missing. I can't use setViewContent(R.layout.activity_main) because the activity cannot reference to the xml layout (due to the missing R.java). Also, when using the (ctrl + space) to get suggestions for setContentView, the code is not typed in. Upon looking at the error log, it shows that there was an "Unhandled event loop exception". The plug-in involved is the org.eclipse.ui.

Also, whenever I create a new Hello World project, the gen folder is empty. After a few hours, I tried the android studio. But I didn't like it there. Then, when I went back to Eclipse, there was an update for SDK platform tools and build tools. I updated them but I still get the errors.

I tried cleaning the project but no luck. What seems to be the problem?
