I am developing my Android project, After I removed a unused library, I got the error:
myproject/gen already exists but is not a source folder. Convert to a source folder or rename it
In my Activity code, all resources from R.java
can not be resolved.
I tried, right click on my project => Java Build Path => under "Source" tab, I added gen/ as source. But it does not help with the problem...
Why, how to get rid of this problem?
----UPDATE----
I found that, the eclipse also complain that "Project has no project.properties file! Edit the project properties to set one." , but I do have project.properties file under my project. Why it complains? I have cleaned the project and "fix project properties" but it does not help.
I get the same problem.
Two actions, first:
second: (because the previous action asked me to remove something... I do not remember what it was...)
And now it works for me!
