R.java malfunctioning

Question

I created a new xml file, and had an errant ? in it that prevented R.java from regenerating. I tried Cleaning the Project, and Fixing the Project Properties but no luck.

Then I realized the XML was creating the R.java from recreating itself, so I deleted the XML file and the R.java was back.

Now though, I am getting an error on all the calls to R.. calls saying that :

• cannot be resolved or is not a field

So, for instance I have

setContentView(R.layout.detectlayout);

ERROR: detectlayout cannot be resolved or is not a field

for all of my calls to 'R.'. Any ideas?

I have tried all of the suggestions on SO already to no luck =/

Answer 1

Look at the 'import' section of your code. Since you deleted your original R, chances is Eclipse help you to fill in the R as com.android.R instead of com.yourproject.R

I also sometimes have problem in Eclipse Resource stuff, sometimes I found turning off and on the "auto buiild" function may help, or simply restarting Eclipse may sometimes help. It's kind of buggy under Mac OS.
