I don’t have idea on why it happened. Please help!!!
Thanks in advance!!!

Nov 21 18:21:10.451 BUILD ERROR: There was a problem linking the app.

You are using the official Appodeal plugin, I don’t believe that one works currently.

Thanks for the Appodeal plugin, @agramonte! I just ran into the same issue with iOS and your plugin took about five minutes from signing up on the Plugins Market to incorporating and building. Successfully serving test ads.
Do you know if your plugin works for Amazon? I know the Solar2D documentation says the official plugin doesn’t, but the Appodeal dashboard lets you create an Amazon app.

@colinmorgan It does. It runs and shows ads. For some reason even though it says you can use Chartboost, I can’t get my Amazon devices to show Chartboost ads on Appodeal. Appodeal is looking at it and it might be just my account. Chartboost currently is producing very high eCPM on Amazon apps (somewhere between iOS and Android eCPMs). For this reason, I have been using my ironsource plugin for Amazon apps, but the Appodeal will work and show ads.

@agramonte That’s great news! I’ll implement it ASAP. Thanks again!

Thanks agramonte, so what will be the best method now to implement ads in ios and android app?
is it just admob plugin?

besides, my builds.setting is: (Please let me know how to correct it or simply use admob plugin is easiest)

thanks… I’ll try to use it and let you know whether I got problems… thanks for kindly share.
