Line 15 and 22 complain that
R cannot be resolved to a variable


I have tried removing the

statement and even renaming it to import com.HelloWorld.firstandroidproject.R;

but the syntax errors still persist ...

any ideas?


Thanks a bunch everyone

You should not have to import anything, it should just work - how are you building the project? The R.java (and R.class) files are generated automatically, and part of the package that's listed in AndroidManifest.xml - which in your case should be "com.example.firstandroidproject", not "com.HelloWorld.firstandroidproject".

My package name is as you say it com.example.firstandroidproject;

Im pretty much creating a android virtual device and then attempting to launch it , I have even tried 'cleaning' the project to from the 'project' menu in eclipse.
