MultipartEntityBuilder requires httpcore, but this is causing conflict with internal version. Any fixes?

Question

I am working on an app which requires the use of MultipartEntityBuilder. To use this I have included org.apache.httpcomponents:httpmime:4.4

Here is the code snippet from the app:

MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
        builder.addPart("file", new FileBody(new File(filePath)));
        builder.addTextBody("type", type);
        builder.addTextBody("phone", pPhoneNumber);

Now the issue is, FileBody here requires ContentType class which is included in org.apache.httpcomponents:httpcore. But if I import this in Gradle, I am unable to proceed with compile due to conflict with internal version of provided by Android. I am getting following error:

Error:duplicate files during packaging of APK /somepath/app/build/outputs/apk/app-debug-unaligned.apk

Please suggest a solution.
