Please don't make it duplicate because i have tried below all the things

• Clean project
• Rebuild project
• Deleted /.gradle folder in project after Reopen project and clean and rebuild
• Deleted .gradle cash folder after Reopen project and clean and rebuild

Other think is i checked below stack overflow questions and its answer and other also then also i don't get the solution.

Please do some help that how i can fix this issue. May i know if you need any thing from my side. Help would be very appreciate. Thank in advance.

Answer 1

I agree with @CommonsWare that there is one another lib also contain commons-io in your project.

There is an option to fix this conflict issue in gradle dependency. Add below code in your app level build.gralde file.

configurations.all {
    resolutionStrategy.dependencySubstitution {
        substitute module('org.apache.commons:commons-io:1.3.2') with module('commons-io:commons-io:1.3.2')
    }
}

Reason is that why that 'org.apache.commons:commons-io:1.3.2' is conflict Check this stack overflow question's answer.

Note:- To know more about apache commons collections and its different versions check this answer

Answer 2

If you're explicitly including this dependency in your build.gradle file:

org.apache.commons:commons-io:1.3.2

replace it with this one (or a later version):

commons-io:commons-io:2.4

You may need to do a clean/rebuild to get rid of a cached version. The org.apache... named one is both misnamed and now very out-of-date. Weirdly, some other org.apache... named ones are apparently OK.
