Java-NoClassDefFoundError，Android库项目

Question

I create library project in eclipse - LibProject1. Than I create library project - LibProject2 that use LibProject1. Than I create Android App that use LibProject2.

If I add LibProject2 to Android App like: Right click on project -> properties -> Android -> Add -> add LibProject2 . App runs without errors.

I want to create jar file for LibProject2 that contains LibProject1 and add jar to Android App.

I do: LibProject2 -> Right click on project -> Export -> Java -> JAR file -> finish .

When i run app i get NoClassDefFoundError , no found LibProject1 class. In JD-GUI i see that LibProject2 contains LibProject1. Where is a problem? Thx.

right click on project >
   then to project properties > 
      java build path >
        last tab order and export

there you see those jar unchecked. first check it then [clean and rebuild]... It will work. cheers :)
