我在 admob 中创建了一个新的 android 应用程序，我得到了 id，我尝试在 firebase_admob 页面上的示例中使用它。

我已经在默认的 flutter 项目中添加了最新版本，并将代码复制并粘贴到页面上。我只修改了id，我试过单引号，我试过双引号，都没有用，我在控制台中出现了同样的错误。

我做错了什么？我真的不明白，我花了一整天的时间试图弄清楚这一点。请帮助我。

getGoogleAppId 失败并出现异常:java.lang.IllegalStateException:必须在 getGoogleAppId 之前调用初始化。:com.google.android.gms.measurement.AppMeasurement.getGmpAppId(未知来源:0)

我也报错

GoogleService 初始化失败，状态:10，名称为 google_app_id 的字符串资源中缺少 google app id 值。

和

缺少 google_app_id。 Firebase 分析已禁用。看...

这是代码:

import 'package:flutter/material.dart';
import 'package:firebase_admob/firebase_admob.dart';

// You can also test with your own ad unit IDs by registering your device as     a
// test device. Check the logs for your device's ID value.
const String testDevice = 'YOUR_DEVICE_ID';

class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {

static final MobileAdTargetingInfo targetingInfo = new MobileAdTargetingInfo(
testDevices: testDevice != null ? <String>[testDevice] : null,
keywords: <String>['foo', 'bar'],
contentUrl: 'http://foo.com/bar.html',
birthday: new DateTime.now(),
childDirected: true,
gender: MobileAdGender.male,
nonPersonalizedAds: true,
);

BannerAd _bannerAd;
InterstitialAd _interstitialAd;

int _coins = 0;

BannerAd createBannerAd() {
return new BannerAd(
adUnitId: BannerAd.testAdUnitId,
size: AdSize.banner,
targetingInfo: targetingInfo,
listener: (MobileAdEvent event) {
print("BannerAd event $event");

}

  adUnitId: InterstitialAd.testAdUnitId,
  targetingInfo: targetingInfo,
  listener: (MobileAdEvent event) {
    print("InterstitialAd event $event");
  },

}

@override
void initState() {
super.initState();
FirebaseAdMob.instance
    .initialize(appId: 'ca-app-pub-0463943530925483~4865006927');
_bannerAd = createBannerAd()..load();
RewardedVideoAd.instance.listener =
    (RewardedVideoAdEvent event, {String rewardType, int rewardAmount}) {
  print("RewardedVideoAd event $event");
  if (event == RewardedVideoAdEvent.rewarded) {
    setState(() {
      _coins += rewardAmount;
    });
  }
};
}

@override

_bannerAd?.dispose();
_interstitialAd?.dispose();
super.dispose();
}

最佳答案

最新的插件有问题

我能够通过更改打开应用程序:firebase_admob: ^0.5.5

和:

dependencies {
    api 'com.google.firebase:firebase-ads:15.0.1'
}

并使用我的 AdMob key 添加到 AndroidManifest.xml:

 </activity>
        <meta-data
            android:name="com.google.android.gms.ads.APP_ID_HERE"
            android:value="ca-app-pub-XXXXXXXXXXXXXXXX"/>
    </application>

还有

FirebaseAdMob.instance.initialize(appId: "appid");
