Guava Library Duplicate Entry Error

I am trying to use guava library in my application. But I am also using chromium_webview project from github. This webview project contains guava library. And I get the following

Solution 1:

I actually did fix this problem, forgot to post it.

So the issue here was I was using maven/gradle dependency in my project BUT the chromium_webview library was using an actual JAR file as a library.

I modified the library to use the maven/gradle dependency. Android Studio and Gradle did all the work for me and excluded the necessary classes.

So make sure they both (library and your module) use the same method. compile 'com.google.guava:guava:18.0'

I really hope this helps someone. Thank you.
