I've followed those instructions carefully (more than once!) - originally, when I first setup B4A, plus serval times in the last few days when I started getting the error.
My SDK number still does not match the number above, and I'm still getting the "com.google.guava/listenablefuture" error.
Are those instructions the only way to update the SDK from 4333796 -> 6609375? (cause that's not working for me)
