' Cleaning and building all projects is recommended'

Question

"The project cannot be built until its prerequisite upomp_Res is built. Cleaning and building all projects is recommended"

When I build an android project as usual, an error occurred as above. Follow that infomation ,i cleaned my 'upomp_Res ' project and then cleaned my main project for several times and the error still remains,and I reopend the project ,and even reopend my eclipse,it dosen't help,the error remains.

How to solve this? Any suggestion would be appreciated.

Answer 1

Even you cleared your 'Upomp_Res' Project , Eclipse will keep Launch configuration for that project. You need to Navigate Run->Run Configuration . Under Android Application right click on 'Upomp_Res' and click remove
