When I press the run button in Android Studio, my app compiles but shows this error (redacted):
Error:Program type already present: android.arch.lifecycle.LiveData
I've tried deleting the .gradle
folder, then going to Build > Clean Project
and Build > Rebuild Project
. However, it doesn't work. I've also tried deleting the source code, then cloning again from git
and importing the folder to Android Studio. However, it still produces that error.
Here's my app's app/build.gradle
:

Apparently, this is intended behavior:
com.firebaseui:firebase-ui-firestore:3.1.0 depends on android.arch.lifecycle:extensions:1.0.0-beta1. Switching to version 3.2.2 fixes the issue by using the Lifecycle 1.1 libraries that Support Library 27.1.0 are built upon. - Issue Tracker
For me, removing the firebase-ui
dependencies solved the issue since I wasn't even using the library in the first place.
