    I have recently upgraded to the latest version of B4A

    and opened an existing project to implement ads. I have gone through the instructions but continue to receive the following error. I have also tried running with a brand new blank app and get the same error as soon as I try to add the library to the project or attempt to build any project that has this library checked.

    An error occurred.

    What I have installed pretty much everything firebase in the SDK manager:

    you are not using the same sdk.
    your sdk is in c:\androidsdktools so the path to android.jar should be c:\androidsdktools\platforms\android-28\Android.jar

    PS: It is a mistake to put the SDK into the programfiles folder as this is a restricted folder.
