I read an article (in Russian), which says that it is because of a conflict of libraries enter link description here

to fix the problem I'm trying to

configurations {
    all*.exclude module: 'httpclient'
    all*.exclude module: 'commons-logging'
}

Library exclude I got, but the error is not lost

Answer 1

In order to investigate your problem, I created an empty project and added your dependency

compile 'com.balancedpayments:balancedpayments:1.4'

to app/gradle.build.

Got your errors. So what I did to finally build and run the project without errors:

In the same gradle.build add the following:

packagingOptions{
     exclude 'META-INF/LICENSE.txt'
     exclude 'META-INF/NOTICE.txt'
}

missing this entry will lead later to

Duplicate files written in ...

your exlude in dependencies won't help, so clean them.

and finally add

configurations {
   all*.exclude group: 'org.apache.httpcomponents'
   all*.exclude group: 'org.apache.commons'
}

Synk gradle and hit Run to check if I'm right.

Notice that org.apache transitive dependency could be added to base dependency for some reasons, such as incompatibility with Android stock org.apache components. So it's up to you to check if com.balancedpayments will work.
