Admob banner disappears after interstitial is closed (iOS)

Solar2D Monetization (in-app purchases, ads, etc.)
#1

Hi,

I noticed a strange behavior of banners since I have updated to AdMob v2.

I successfully implemented both banner and interstitial on iOS but after an interstitial is shown and closed the banner previously shown disappears. It doesn’t refresh and there are no chances to see it later.

This problem doesn’t happen on Android.

I logged the app while this problem and every time an interstitial is shown, I can read the following creepy log:

Generic error: NSInvalidArgumentException: *** +[NSString stringWithCString:encoding:]: NULL cString

(Ueue is the name of the app).

The code is quite simple as you can check here:

local platName = system.getInfo( "platformName" ) local bannerId = {ios = "ca-app-pub-xxxxxxxx1",android="ca-app-pub-xxxxxxxx2"} local interstitialId = {ios = "ca-app-pub-xxxxxxxx3",android="ca-app-pub-xxxxxxxx4"} local flurryId = {ios = "ABCDEFG", android = "HIJKLMNO"} -- ANALYTICS AREA local analytics = require ("analytics") local ga = require("GoogleAnalytics.ga") -- END ANALYTICS --ADS AREA local ads = require( "ads" ) local shownBanner = bannerId.ios local shownInterstitial = interstitialId.ios local shownFlurry = flurryId.android local function adListener( event ) if ( event.isError ) then print("error") elseif ( event.phase == "loaded" ) then -- an ad was preloaded print ("loaded") elseif ( event.phase == "shown" ) then ads.show( { x=display.screenOriginX, y=0 } ) print ("shown") end end local function showInterstitial () ads.show( "interstitial", { appId=shownInterstitial} ) end if platName == "Android" then shownBanner = bannerId.android shownInterstitial = interstitialId.android shownFlurry = flurryId.android end -- BOTH ANALYTICS AND ADVERTISING AREA analytics.init( shownFlurry ) ads.init( "admob", shownBanner, adListener ) ads.show( "banner", { x=display.screenOriginX, y=0, appId=shownBanner } ) timer.performWithDelay( 45000, showInterstitial ) -- shows the interstitial after 45 seconds

Did you experience a similar issue?

Thanks in advance!

Hi,

anyone from Corona Labs here, please?

Thanks!

#3

Please, Does anyone from Corona have an answer, a clue or a suggestion?

Here you can find the video of the issue.

I re-produced it with less code than the example above. You just need to implement both interstitial and banner in order to reproduce the bug:

Have you tried to call ads.hide() before you try and show your interstitial?  Are there any other errors?  Are you printing out any results from the ad listener?

Hi Rob,

thanks for your help. I used the following code in order to prevent the problem described above and it worked:

local function adListener( event ) if (event.type == "interstitial") then if (event.phase == "shown") then ads.show( "banner", { x=0, y=0, appId=xxxxxxxx } ) end end end
