Hey guys I'm so speechless with these errors. I have no idea to fix them but I can only tell you what I'm trying to do.
So basically I'm trying to show interstitial ads using xamarin forms prism. I'm using dependency service from prism and combine it with someone's project sample on github and got 100 errors.
Looks like I'm missing some packages in com.google.android.gms.common but I don't know. 
Any idea to solve this problem ? Thanks
