Error: android defines classes that conflict with classes now provided by Android , when we start to generate release build

Question

I had several libraries conflict issues. That i resolved by adding

configurations {

all {
    exclude module: 'httpclient'
    exclude module: 'commons-logging'
    exclude group: 'org.json', module: 'json'
    exclude group: 'org.apache.httpcomponents'
    exclude module: 'xmlParserAPIs'
    exclude module: 'xpp3'
    exclude module: 'opengl-api'
}

}

But still following error present. And i am unable to build signed apk. I have tried project clean/rebuild option.

Error: android defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don't have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar. [DuplicatePlatformClasses]

Thanks in advance for your help.

Problem

How to see which dependency is creating conflicts. It is same like shooting in dark.

Solution

Some AS plugin that will show you which projects dependency hierarchy. You can find where issue presents exactly and solve that.

Gradle View is an Android Studio plugin that you can install and show dependency hierarchy.

Methods Count is another plugin, it also shows dependency tree.
