React-native-admob: The ad unit ID can only be set once on InterstitialAd

[justfede]

Hey guys! It's anyway to check if unit ID is already setted up to avoid this exception?

Thanks!

I had the same problem, in my case I fixed the problem setting the IntersitialAd id just in index.android.js and index.ios.js

@mihaben how did you go about doing that? I tried and it just causes the app to crash.

I'm having the same error @mihaben from where did you removed it ?

Hey @fcpauldiaz and @marcusds , I was setting the InterstitialAd inside a component, so.. every time that the component was rendered, the InterstitialAd was setting again and that was provoking the problem, to fix the problem I moved the next 2 lines:

AdMobInterstitial.setAdUnitID('ca-app-pub-you-id');
AdMobInterstitial.setTestDeviceID('EMULATOR');

to index.android.js and index.ios.js, in this way you are just setting the ads when the app is started.

And inside the component, the code to show the ad:

AdMobInterstitial.requestAd(AdMobInterstitial.showAd);

[emrecanozkok]

set to global variable top of the index.js
var adIdSet = false;

and when you show itiyou need to check and your first time you wil need to set.

if (adIdSet != true) { AdMobInterstitial.setAdUnitID('ca-app-pub-2379123131358452/1851902925'); AdMobInterstitial.setTestDeviceID('EMULATOR'); AdMobInterstitial.requestAd(AdMobInterstitial.showAd); adIdSet = true; }else{ AdMobInterstitial.requestAd(AdMobInterstitial.showAd); }

Hmm I still having this problem when the user minimize (android back button) the application and reopen it later...

[fcpauldiaz]

That must be because you open the interstitial on the onMount event, you have to move it before class declaration.

I had the same problem on production.
Pull request #121 can fix this issue

moving it before class declaration work for me thanks @fcpauldiaz

We're bumping into the same issue.
It seems like everywhere else (like rewarded video, banner module, etc), before setting the ad unit id, there's a check whether the ID has been already set or not, except for InterstitialAd.
Is this intentional?

I think all of our problems would be solved if there was a check in RNAdMobInterstitialAdModule.java, too.
