I wanted to create a simple application to test drive it. The wizard created this code: package eu.mauriziopz.gps; import android.app.Activity; import android.os.Bundle; public class ggps extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } but Eclipse gives me the android r cannot be resolved to a variable after clean error R cannot be resolved on line setContentView(R.layout.main); Why? PS: I do have an XML file named main.xml under res/layout/. android eclipse compiler-errors android-resources android-sdk-tools share|improve this question edited Jun 16 at 8:41 community wiki 9 revs, 6 users 58%Maurizio Pozzobon For those who still experience some problem with eclipse not being able to update/generate R.java. A possible solution is by creating a dummy xml and just delete that xml. In my case this is the solution –denil Jun 25 '12 at 10:59 Honestly, this sounds so stupid (and it is), but modifying the AndroidManifest.xml, then undoing that edit, then saving the file worked for me. If I cleaned the project after that, it broke again. And all this time I thought Xcode was the only IDE that had these kinds of mysterious errors. –iWasRobbed Dec 22 '12 at 18:12 2 Did you try right click on the project -> Android Tools -> Fix Project Settings? –Sergei Feb 1 '14 at 10:59 3 Please check your XMl layout file, if any error in xml you can't generate R.java, and the error comes after bulid and clean also. –RDC Feb 20 '14 at 11

[duplicate] 30 answers I am getting this classic error in Eclipse IDE. I am bored of Eclipse's bugs. They driving me mad. I almost tried everything which suggested as solution (by Googling).

Eclipse, Xcode keep on changing every year and old solutions don't work anymore. Perhaps SO can suggest the latest similar questions so that many people wouldn't have to trawl old questions for hours before stumbling across the latest one. –Pritesh
