Android: added a project as a library, receiving (missing) .jar file in the build path> Libraries> Library projects

Well, I tried to find a solution for this for about half a day.

I have two projects in the workspace. One of them is the main one, I will call it Alpha, the other is used as a library for the main one, I will call it Delta.

Delta has a marked "library" and has no errors (only yellow triangles with an exclamation mark).

Alpha added Delta as a library (in the "Select Android" section in "Project Properties"). As soon as this is done, I get a big, thick red exclamation mark from Alpha. In the Alpha Build Path, on the Libraries tab, there is a red “x” in the “Library Projects”. When expanding this option, I see:

delta.jar - /Users/.../Delta/bin (missing)

I really don't understand why this will be absent. 1st, there is a bin folder. Secondly, I import the project library, not .jar. 3rd, even if it creates a project library .jar file, it seems that it compiled correctly, Delta does not have erros.

I'm really here in the dark. Please help.

thanks

If you use SDK Tools, version 14 and ADT 14.0.0 and higher, there are changes in the way jar-based libraries are created. I recommend you check out the library project update here.

I had this problem, especially when I switched to Android SDK 18 on OSX. Without marking the project as a library or importing an existing library project, you will create a jar file.

I upgraded to 19, and he left, now banks are being created, and I generally did nothing for the project or the settings.

Hope this helps someone, I struggled for hours like an OP.
