Answer 1

I resolve this problem when integrated Facebook 7.19.2 and Google play Games 0.10.09.

In my case JDK and SDK using (and other in Edit/Preferences/External -> Tools-Android) default paths Unity:

JDK

C:/ProgramFiles/Unity/Hub/Editor/2019.2.12f1/Editor/Data/PlaybackEngines/AndroidPlayer/Tools\OpenJDK\Windows

SDK

C:/Program Files/Unity/Hub/Editor/2019.2.12f1/Editor/Data/PlaybackEngines/AndroidPlayer\SDK

In Environmental Variables(System Proporites/Advanced) added next:

Find(or click new variable under User Variables)

• JAVA_HOME and add root JDK path.

• JAVA_BIN and add path JDK/bin

• JAVA_LIB and add path JDK/lib

Also, add these paths in System Variables to variable "Path".

Do not use SDK from default Unity and JDK from not Unity default

Then Restart Unity(and better PC).

Then in Editor Unity - Assets/Play -> Service -> Resolve/Android -> Resolver/Force -> Resolve

All Work fine.
