R.java was modified manually! Reverting to generated version

Question

I have the emergency live tracker sample apk file. So I run that application via eclipse.

I am getting an error.

Answer 1

Just clean your project and then rebuild it. That will automatically generate a new R file.

Answer 2

I had that problem and it turned out to be some weird side-effect of me not using the proper Java compiler: I used to use 1.5 for earlier SDK versions but I had to use Java 1.6.
