Description:

build failed using the latest version of  Admob and one signal.

Execution failed for task ':processReleaseManifest'.

Manifest merger failed : Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [:androidx.core.core-1.0.0:] AndroidManifest.xml:22:18-86
is also present at [:com.android.support.support-compat-28.0.0:] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory).

Hi Mubshar,

Thank you for reaching out to us. Kindly note that we can only promise full support for the AdMob SDK, and cannot assure the same for third-party products such as the OneSignal SDK. That said, you may see our analysis below.

The reason that the Unity build process was failing was because the project contained both AndroidX and Support Libraries, after dependencies were resolved. This caused classes to be erroneously declared twice (one in each of the above-mentioned libraries). You may try deleting all the Support Libraries after the Play Services Resolver has finished resolving dependencies, then build/export the project afterwards (please see attached screenshot); I was able to both build and export the project after attempting the above procedure.

Let me know if this works for you.

Hi guys,

The solution from Ziv Yves Sanchez works for me. But only if I'm trying to build in manual mode.
If I'm trying to make automated build, it gives me such error:

FileNotFoundException: Assets\Plugins\Android\com.android.support.support-compat-27.1.1.aar does not exist

My automated build workflow:
1. Synchronous code for ResolveAndroidDependencies.
2. Code for removing "android support .aar files".
3. Code for building APK.

Logs show me, that everything is done as expected, but it throws error brfore the end of build pipeline. I think something still trying to add .aar files to the final build. Can you help me to fix the issue?

Nevermind, I fixed the issue.
Just needed to add AssetDatabase.Refresh(); after delete support files logic.
