No generated R.java file in my project [duplicate]

by

Go to Project and hit Clean. This should, among others, regenerate your R.java file.

Also get rid of any import android.R.* statements and then do the clean up I mentioned.

Apparently Jonas problem was related to incorrect target build settings. His target build was set to Android 2.1 (SDK v7) where his layout XML used Android 2.2 (SDK v8) elements (layout parameter match_parent), due to this there was no way for Eclipse to correctly generate the R.java file which caused all the problems.
