Can't Export Android Application in Eclipse

Question

I'm experiencing some strange behavior in Eclipse. I'm trying to export my Android application, which is a game that is written using AndEngine, the open source game engine. Not sure if that is relevant.

Anyway, there are no errors in my project or the library dependencies of Android. I have been running the application on my phone with the debug build for ages. Now I want to export a signed application, and it won't work! (It did used to).

I right click my project, click Android Tools > Export Signed Application and right when I do that, two errors show up that say,

No .class files were found in project "AndEngine" so none of the classfile basechecks could be run . Does the project need to be built first?

No .class files were found in project "AndEnginePhysicsBox2DExtension" so none of the classfile basechecks could be run . Does the project need to be built first?

How the heck do I fix this? I have done a Project > Clean, open and closed Eclipse, open and closed the individual projects. And again - this error is NOT there until I go to export the app! What the heck!

Answer 1

Ok I think I figured this out. Not sure of the "real" issue, but my workaround for the time being is to right click my project in the file tree on the left, then click Properties. I selected the "Android Lint Preferences" in the dialog that comes up, and just hit "Ignore All". Now I can build without the error.

While this is a work around, I'm not thrilled about leaving that disabled completely. I'd like to know which Lint preference i can specifically disable. (I, quite frankly, don't even know what lint is)

Answer 2

I solve this problem turning off Build Automatically in Eclipse before export.
