Android R constants do not support auto-update

Question

I searched high and low for people with the same question, but found only some options (i.e. the R file is not generated at all) that do not help. I am VERY new to Android development (first day, actually), but from some of the tutorials I read, this behavior is unexpected. Basically, let's say I create a TextView in my activity XML file and give it the corresponding android: id. I save the file (and all other files), but if I try to use findViewById in my Java file, then the name is R.id. [view name] will not be displayed (and displays an error if I manually type it). If I run the Build Project, it works, but there will be a huge load to run the Build command when creating each new component! Has anyone else experienced this or had ideas on why this is happening? Thanks in advance!

If everything else that you mentioned is true, then the only way for you NOT to get the correct R variables is that you can import "android.R;" a file instead of your actual R file "your.package.R", which contains the variables you are looking for.

You may need to tell your IDE that you need to automatically rebuild your changes. For example, in Eclipse, it will: Window > Preferences > General > Workspace. Make sure checked Build automatically.
