Problem starts when i try to add adview in project based on this tutorial ( i didnt change antything) -> https://www.b4x.com/android/forum/threads/appcompat-with-toolbar-minimal-example.79896/#post-509530. This is error

B4A line: 92
Activity.AddView(adview1, 0dip, 100%y -50dip, 320
javac 1.8.0_60
src\network\assist\com\main.java:412: error: cannot access AdView

                                                                                ^
  class file for com.google.android.gms.ads.AdView not found

this is the line 91,92,93

adview1.Initialize("Ad", "<ca-app-pub-xxxxx")
Activity.AddView(adview1, 0dip, 100%y -50dip, 320dip, 50dip)' AdView1.LoadAd 'loads an ad
adview1.LoadAd
