Gradle failed to fetch dependencies for Unity Mediation, Firebase, and Google Play Service

Time:10-31

I am not able to force resolve this issue. Until a few days back it was working fine. I assume after installing a package from Unity Mediation made this all issues. After which, I removed that package and still this error isn't solved.

Even I tried to reimport all those packages once again. Still, the issue persists.

CodePudding user response:

  1. In the Unity Editor, open your project and go to Project Settings > Player > Publish Settings > Custom Main Gradle Template and ensure the Custom Main Gradle Template checkbox is enabled.
  2. Then, go to the Project tab and navigate to Assets > PlayServicesResolver > Android Resolver > Force Resolve.
  3. Now try to build the project. (With these settings, Android dependencies will not be included directly in the project anymore)

This will resolve all the dependencies. In case if you have trouble while taking build (Gradel Build). Go to Project Settings > Player > Publishing Settings and select the Custom Gradle Properties Template checkbox. Then Navigate to the path below the checkbox and add these two lines to the end of the file:

android.useAndroidX=true
android.enableJetifier=true

And then take a build. hope it works.
