Yeah, so both the Facebook extension and the AdMob extension use and include a jar for com.android.support.customtabs. This and the other support libs should probably be moved to a base extension.
@Dragosha can you please share the list of dependencies you have when AdMob and Facebook works together?
My latest app on store builded with this dependencies:

and also GitHub - Dragosha/defoldgamecenter: Defold Game Center native extension as project folder.
Which list of dependencies need to build latest release FB extension now?
Iāve tried this as mention in updated docs:

list of all included (removed admob for pure experiment)

removed for post size resone
Latest version is 2.3.1. It depends on:
I will make a separate post later today about changes to the Android base extension dependencies to bring some clarity. Sorry for the temporary confusion.
it works!
Build error when tried to make iOS bundle:
Ah, thatās because the 2.3.x version needs the 1.2.164 server.
Weāre scheduled to release a new version today, in the mean time, you can use https://build-stage.defold.com
You need both the new version and the new server, weāre working on itā¦
Will purchase events be posted to FB analytics automatically?
Referring to this https://developers.facebook.com/docs/analytics/send_data/events:
So, if Iāve kept this checkbox, will the purchase be logged automatically by the FB extension?
Ok, I see IAP events in FB Analytics dashboard, so it works (and I did not send these events manually).
But I see 2 events, when there was only one purchase (and it was restored more than 2 times). 
Hi. I see the 6.3.0 version of android facebook SDK was released recently:
And, Iām not 100% sure, but it seems supporting AndroidX now (at least I see in commits some related stuff, and switching to 28 version of android SDK as well).
Is it possible to update the extension?
Iāve tried to update android part by my own, updated dependency in build.gradle, fixed references in code from old support libs to new androidx libs, but stuck with susch error message:
Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from AndroidManifest.xml:24:18-86 is also present at AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory).
Possible solution Iāve googled is setting these lines in gradle.properties:
android.useAndroidX=true
android.enableJetifier=true
But I donāt see a way to modify properteis files and donāt know if it already set so.
Weāre still using Android 28, and updating is ofc on our roadmap, but itās in there with other features.
It usually requires a lot of testing, and also upgrading a lot of extensions to make sure they still work.
Let me remind you that weāre not actually using gradle to build Android, we merely use it to resolve packages, to avoid the manual unpacking and conflict resolution. Therefore itās not as simple as setting a property in your gradle file.
As for always chasing the latest version of every package, let me tell you itās a very big timesink, and often with pitfalls. Thatās also one of the reasons we tend to delay updates a bit.
As for the feature, whatās the use case? What feature in that facebook upgrade do you wish to use?
Iām forced to switch to AndroidX āwayā by other extensions - Admob, Firebase, IronSource. All this can work on old versions, if you made extensions at the same time somewhere in the past, when AndroidX was not pushed by Google. But for example for IronSource itās not an option, I canāt use old version of IS and ad network adapters and SDKs. And this affects all other extensions, which do not support AndroidX. In my case only Facebook SDK is the problem. Everything else is up to date.
BUT, just because the Facebook extension uses old support libs, it brokes all other extensions, which already migrated to AndroidX way. So I either should throw away Facebook SDK (what means no FB ads for UA, as tracking will not work), or throw away Admob and Firebase (what means no Google Ads both for monetization and UA).
Right now Iām using old Firebase extension version for Android build, it works with old FB extension, but I canāt add Admob; and using up-to-date Firebase for iOS, because the old one conflicts with Admob on iOS. This setup is already complicated and I was waiting for official support of AndroidX from Facebook, now itās live and I want to use all the libs up to date and synced.
Iām still trying to update the FB extension and prepared a branch just to illustrate the issue Iām stuck with.
Here is a dev branch in forked repo from original defold facebook-extension: GitHub - MaratGilyazov/extension-facebook at update_6.3.0/android
I did just few changes: switch to Facebook android SDK v6.3.0, Ā· MaratGilyazov/extension-facebook@997d9e2 Ā· GitHub
First of all - switched dependencies to a new 6.3.0 SDK (now there is only one dependency required). If keep just this chane - extension itself can be build without any issues.
But in a real project I also need Admob, so Iāve also added a dependency for Admob just to illustrate the conflict - now it fails with the message, Iāve mentioned in previous messages:
Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from AndroidManifest.xml:24:18-86 is also present at AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory).
Thats the main issue I canāt solve by my own 
support libs.android.enableJetifier=true
android.useAndroidX=true
But when I try to build from such state, it fails with such error:
And anyway, this class seems to be not used here at all, so Iāve simply commented it out, but this thing is minor, as build fails on step (2).
Any ideas what Iām doing wrong and how to fix the issue?
BTW, if I use only dependency to Admob itself, without facebook, it builds normally (in my ironsource extension, for ex), so build fails only in combination of FB extension and other up-to-date plugins like Admob or Firebase
Donāt you just love how messy Android development can be sometimes 
Important to keep in mind is that we use Gradle only to resolve project dependencies. The android.useAndroidX=true setting will be ignored.
The problem as I see it is that Facebook 6.3.0 still uses android.support.v4.app:
https://mvnrepository.com/artifact/com.facebook.android/facebook-common/6.3.0
Also, I found an interesting discussion in FB rep (especially last 2 comments): https://github.com/facebook/facebook-android-sdk/pull/689
So actually they did not switch to AndroidX yet 
ā¦
I saw that this PR named āUpdate to AndroidXā was not merged, but also there was something said about āthis will be supported internallyā and at first I thought this commit covered what needed:
But obviously it just switches version of used support libs, and itās not about mirgation to AndroidX.
Ok, Iāll be waiting for further updates in FB repo.
Thanks for checking and sorry for disturbing on Saturday
And this Jetifier tool seems to be used for such migration āmanuallyā somehow, but I donāt think itās a right way to even give it a try: https://developer.android.com/studio/command-line/jetifier
We have updated the Facebook extension to use Facebook SDK 6.5.1 for Android and iOS:
This is the last release on the 6.x branch of SDKs and the last SDK release which uses the old version of Android Support libraries. AndroidX is included in versions starting from 7.0.0 of the Facebook SDK for Android.
NOTE: We will not yet make this update to AndroidX as we also need to modify the build system to use the jetifier tool to automatically upgrade extensions to use AndroidX.
This Facebook blog post states that the version of the SDK used by extension-facebook (9.0.1) will be āsunsettedā on June 8, 2023 this year - not just deprecated but apparently will no longer be operational.
I wasnāt able to find any further announcements, but v11 will suffer the same fate in October, and v12 and v13 are already deprecated.
v12 introduces a minimum requirement of iOS 10.0 (previously 9.0), v13 requires iOS 11.0 and v15 requires v12.0
Iām tempted to try an upgrade (although if it was too challenging I wouldnāt be able to spend much time on it) - any thoughts on which version? Personally Iād likely go for 14.1.0 which is the latest before the v15 upgrade requiring iOS 12.0. The latest v12 (12.3.2) is tempting but is already halfway through its 2-year deprecation period.
I would suggest that we try with v14.1.0, especially now that we also have Cocoapod support which means that we can get rid of the iOS frameworks. For iOS add a Podfile in manifests/ios, something like this one:
platform :ios, '11.0'
pod 'FBSDKCoreKit', '14.1.0'
pod 'FBSDKLoginKit' '14.1.0'
pod 'FBSDKShareKit' '14.1.0'
