Admob Banner Ad FailedToLoad => nativeToJSError

[SMKH-PRO]

Dear React-Native-Firebase Team.

I have not tried other ads, but i am using Admob banners ad, I created my ad unit on admob 2 days ago (48Hours) and i am trying to request ads since yesterday!.. but it always fails to load the ad

When i am on Emulator it shows test ads without errors, but to check real ads i had to run app on real device so on real device i am always getting failed to load error nativeToJSError

in the start i thought that it may take sometime for admob to be providing ads on my app, but its now been 48 hours!. seems like a bug in the library....

i have seen many issues on the same error but they all are closed without any solution even same error was posted on stack-overflow by someone else, but no solution was there as well, so i had to open new issue !...

and on my Admob there are 0 Requests made!....

I have also tried the release APK the result is same on the release apk.

My BannerAd Component:-

import React, { Component } from 'react'
import firebase from 'react-native-firebase' //Native firebase sdk 
firebase.admob().initialize("ca-app-pub-2326409939639613~3654060702") 

const Banner = firebase.admob.Banner;
const AdRequest = firebase.admob.AdRequest;
const request = new AdRequest();
request.addKeyword('coins');
request.addKeyword('hosting');
request.addKeyword('free');
request.addKeyword('cheap');
request.addKeyword('hosting');
request.addKeyword('crypto');
request.addKeyword('bitcoin');


export default class AdmobBanner extends Component {


  render() {

const {size}=this.props  // <BannerAd size="FULL_BANNER" />

return <Banner
      size={size}

      onAdLoaded={() =>console.log('Ad loaded')}

      request={request.build()}

      unitId="ca-app-pub-2326409939639613/1792036892"

      onAdFailedToLoad={(e)=>console.log('Ad Failed To Load Trigger=>',e)}
    />

  }
}

On other pages to show banner i am importing this component and rendering as
<BannerAd size="FULL_BANNER" /> . just shows blank screen and error on the console!.....

I have also tried creating new Ad Unites but none works!...

Have you added the payment information in Admob ?

Have you added the payment information in Admob ?

Yes, My admob account is verified and is also generating revenue from other apps in the same account.

[SMKH-PRO]

Now my version is "react-native-firebase": "^5.2.5",

The error is same.

Today The Ads Automatically Worked In The Production APK Without changing any code!..

For Other Users facing issue:-

I would recommend to complete your app and Make a Release APK and open it every hour, the more request you hit to admob earlier the chance of getting the real ads!... Also it will show the same error in development mode but working in Release APK after 24 Hours!...

I dont want anyone else to go through the same issue, tried alot of things and other libraries but the actual solution was just to keep hitting on admob from release & signed apk, means keep opening your app your app will request admob and more request means more earlier the chance of getting real ads..
