Solution 1:

Ok heres one specific method I followed where it worked.

• Unity version: 2019.3.15f1

• Facebook SDK version: 7.21.2

• Using the PlayServicesResolver, Resolve libraries

• Do not Delete Resolved Libraries

• Set a Custom Proguard file in the player setting under publishing settings, and add the following two lines to the file..

    -keep publicclasscom.facebook.**{public *; } 
    -keep publicclasscom.facebook.internal.**{ public *; }
  

• Comment out these lines from mainTemplate.gradle

       com.android.support:appcompat-v7
       com.android.support:support-v4
       com.android.support:customtabs
  

So your mainTemplate.gradle will look something like this...

    `// Android Resolver Repos End
    apply plugin: 'com.android.library'

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.google.android.gms:play-services-ads-identifier:17.0.0'// Android Resolver Dependencies Start//implementation 'com.android.support:appcompat-v7:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency//implementation 'com.android.support:support-v4:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency//implementation 'com.android.support:customtabs:25.3.1' // Facebook.Unity.Editor.AndroidSupportLibraryResolver.addSupportLibraryDependency
