On this note, I was wondering: when exactly is R.java updated? Here are some cases that have caused confusion for me.
- I add a new file in the res/layout folder. R.java is NOT updated with my new xml file. I perform a CLEAN on the project and then... - I delete a file such that main.xml is the only file remaining. R.java IS updated! - I delete a file after having added two -- that is, main.xml is not the only file remaining. R.java is NOT updated. Any ideas? I especially am interested in making the R.java file pointing to the newly added xml files (case 1 of the three in my list). -Danny On Sat, May 8, 2010 at 7:23 PM, joshua hublar <joshua.m.hub...@gmail.com>wrote: > Android considers XML-based layouts to be resources, and as such layout > files are stored > in the res/layout directory inside your Android project. > > Each XML file contains a tree of elements specifying a layout of widgets > and their containers > that make up one view hierarchy.
