archive for required library could not be read or is not a valid ZIP file

Question

Before coming to the problem let me explain what I did that has landed me in the problem.

1. I created an account on github and made a repository named Android.

Answer 1

There is other case to display error Archive for required library

Right click on project and open --> project project properties --> java build path --> Android private libs

if there are two jar files with same name then remove one from libs.

jar file may the hidden some times then open you libs folder in window and check if any hidden files are exist Organize --> folders and search options --> view --> check show hidden files and Delete the hidden jar file , The same cass delete if hidden java fies exist in src and packages if any
