sorry late answer, had same problem , found this:

admob doesn't provide test ads. have remove line:

.addtestdevice("b9e3469f4f5b561227675dc9167efc16")

additionally have use test ad unit id provided admob:

android: ca-app-pub-3940256099942544/5224354917

you can find explained in more detail here.
