Have you had an issue with your Android build? it seems that it only needed for debug and logging purposes.... Also, could you test if you have #236 ?

it was working in previous versions without any issues, now when i compile i get resouces not found errors. Even resolver is unsupported version.

Me too, but instead of missing resources - I have something like - Facebook was set incorrectly - see Facebook Settings (the Only thing missing - Android default Debug keystore) I'm currently trying every permutation with Gradle and Google Jar Resolver I can think of, but it seems like you can try using the downloading Android Studio and download through it - the SDK (built tools 28.0.3) and set them in your preferences:

Found a way out -
1) Use Android Studio and Android Studio SDK as was shown pr

Me too, but instead of missing resources - I have something like - Facebook was set incorrectly - see Facebook Settings (the Only thing missing - Android default Debug keystore) I'm currently trying every permutation with Gradle and Google Jar Resolver I can think of, but it seems like you can try using the downloading Android Studio and download through it - the SDK (built tools 28.0.3) and set them in your preferences:

2) Remove all of the plug-ins, Remove IAP (Unity plug-in) and remove folder Library to fully refresh the Unity Project
3) first thing first - import IAP (Unity plug-in ) - ensure that it will ask two prompts - the second one - with I made a backup ( if second prompts was not shown - Unity will not compile all of the dll/aar properly! )
Only if it was not shown - repeat step 2, create new Unity Project - try to use Unity 2018.2 - and add in there IAP, then just copy the UDP, UNITYCHANNEL, UNITYPURCHASING folders into your Unity 2018/2019 plugins folder.
4) In your Unity Build settings - check - Minify with proguard, check custom User proguard
use the following - if using other SDK, plug-ins - test and look which classes are missing, add them inside the progurd file
I'm using ; Google Play Games, Firebase Database, Admob, IAP
content of proguard:

-keep class com.facebook.unity.FB { *; }
-keep class com.google.android.gms.ads.MobileAds { *; }

GameService Rules

-keep class com.google.android.gms.* { *; }
-keep class com.google.games.bridge.* { *; }

Don't obfuscate. We only need dead code striping.

-dontobfuscate

-keep class com.google.unity.** { *; }

5) Import all of the plug-ins except Facebook 7.15.1
6) Ensure to make an Android Resolve!
7) Necessary to Build Android - should work correctly
8) in the same Unity Editor session - import Facebook SDK - uncheck like this and import

Try to use Android resolve - nothing should be new!
9) now import the rest :

After import - try use Android resolve (not Force Resolve) - now it will fix the dependencies

10) Build Android - should work fine!

Stuck with same issue, @studentutu thank you for the solution but an official fix will save a lot of trouble.

Referring to @manofspirit original report, in my case, this turned out to be a Unity 2019 issue with Android keystore file locations. See this thread on the Unity forums: https://forum.unity.com/threads/problem-signing-android-build-with-provided-keystore.647092/

My issue was fixed by choosing a different keystore path in Unity Preferences, and moving my keystore to that location. After that, the build succeeded fine, and there were no errors from the Facebook SDK.
