If I do Project -> Clean and then Build, everything is fine, but if I try to run this Android-project, a dialog comes up: “Your project contains errors. Fix them before running application”, and there’s a red cross on the project name.
There’s no cross on any item in the project tree, and nothing in Console view or LogCat view. So, where’s the error?
The only difference for this project and an earlier working version was that I removed a link to an external .jar file, created folder “lib” and put the .jar in there, and added that .jar to the build path. The .jar is the exact same as the external referenced.
You may need to Refresh your project in order to see the errors. Also, bring up the Problems tab for more specific information (Window > Show View > Other > General > Problems).
