Some days ago I had this problem. https://code.google.com/p/android/issues/detail?id=36174
I still have the problem. Before I Run, i'm doing Project -> Clean.
Now, today, I have another problem. Frustrating. I downloaded this:
http://code.google.com/p/openjleuleu-android-flashlight/
(Not only this project, I have this problem by two other Projects)
Now in eclipse I'm doing File -> Import -> Android -> Existing Android Code Into Workspace. The "Browse" and then "Copy projects into workspace".
And now I get this error:
openjleuleu Project has no target set. Edit the project properties to set one.
openjleuleu Parser exception for /openjleuleu/AndroidManifest.xml: Premature end of file.
The AndroidManifest.xml is empty.
I have downloaded everything new. (android-sdk, Java, eclipse).
