Question 1

react-native-admob vs react-native-firebase admob – which should I use?

Accepted Answer

react-native-admob is a lightweight, dedicated library for AdMob integration, ideal if you only need ads. react-native-firebase includes AdMob as part of a broader Firebase suite, so choose it if you need other Firebase services like analytics or authentication, but it adds more overhead.

Question 2

How to implement rewarded video ads in React Native with AdMob?

Accepted Answer

Use the AdMobRewarded API: first set the ad unit ID with setAdUnitID(), configure test devices, then call requestAd() to load and showAd() to display. Handle events like 'rewarded' for user incentives, as detailed in the README event table.

Question 3

Does react-native-admob support native ads?

Accepted Answer

No, react-native-admob currently only supports banner, interstitial, and rewarded video ads. For native ad formats, you would need to use other libraries or integrate the native AdMob SDK directly, which adds complexity.

Question 4

How to test ads without live AdMob units in react-native-admob?

Accepted Answer

Use the built-in test device support by setting testDevices to [AdMobBanner.simulatorId] for simulators or adding your device IDs. This ensures ads are served in test mode during development, preventing accidental impressions.

Question 5

Is react-native-admob version 2 stable for production apps?

Accepted Answer

Version 2 is in beta, so it may have unresolved issues or breaking changes. For production stability, consider using version 1 from the 1.x branch, but note it might lack newer features or updates from the beta version.

Question 6

What's the difference between AdMobBanner and PublisherBanner?

Accepted Answer

AdMobBanner is for standard AdMob banners, while PublisherBanner supports DFP (DoubleClick for Publishers) with extra features like onAppEvent for app events and validAdSizes for ad size eligibility. Use PublisherBanner for DFP-specific requirements.
