How to Find Which Dependency Adds a Specific Library or Class in Android Studio

How to Debug Which Dependency Adds a Specific Library or Class Encountering a duplicate class error or an unexpected library in your Android project? A common culprit is a   transitive dependency —a library that is automatically included by one of your direct dependencies. Thankfully, Gradle provides a powerful tool to investigate this: the dependency tree. This guide will show you how to generate and read this tree to find the source of any problem library, like the common   listenablefuture   conflict. The Quick Command The simplest way to see your project's dependency hierarchy is to run a command in the terminal. Open the   Terminal   inside Android Studio ( View > Tool Windows > Terminal ). Run the following command: bash ./gradlew app:dependencies This will output the entire dependency tree for your   app   module to the terminal. If your main module has a different name (e.g.,   myapp ), replace   app   with that name: bash ...

Resolving "Duplicate Class ListenableFuture" Errors in Android Studio

How to Fix the "Duplicate Class ListenableFuture" Error in Android If you're working on an Android project and see a build error about a duplicate   ListenableFuture   class, you've encountered a common dependency conflict. This guide will explain why it happens and show you how to fix it. Understanding the Error The error message looks like this: Duplicate class com.google.common.util.concurrent.ListenableFuture found in modules: guava-23.0.jar (com.google.guava:guava:23.0) and listenablefuture-1.0.jar (com.google.guava:listenablefuture:1.0)  This means two different libraries in your project are trying to provide the same class, causing a collision. guava-23.0.jar   contains the full Guava library, which includes   ListenableFuture . listenablefuture-1.0.jar   is a standalone, minimal artifact containing only the   ListenableFuture   class. The conflict arises when one of your dependencies requires the standalone JAR, but your project also inclu...
