Flutter App 将 AdColony 与中介集成

Question

使用 Flutter 设置 AdMob 中介时 (firebase_admob: ^0.9.3+2) 我收到以下错误

注意：我已成功设置 ADmob 集成

我遵循此处提到的所有步骤： Integrating AdColony with Mediation

按照第 3 步，这是我的 app/build.gradle 文件

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'

    implementation 'com.google.ads.mediation:adcolony:4.1.4.1'

}

错误

      FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[17.0.

Answer 1

更改版本后我能够编译代码

这是我用于 firebase 的 pubspec.yaml：

  #Firebase libary
  firebase_core: ^0.4.5
  cloud_firestore: ^0.13.6
  firebase_auth: ^0.16.1
  firebase_remote_config: ^0.3.1
  firebase_dynamic_links: ^0.5.1
  firebase_crashlytics: ^0.1.3+3
  firebase_messaging: ^6.0.16
  firebase_admob: ^0.9.3+2
  firebase_analytics: ^5.0.15

和 android/app/build.gradle

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'

    implementation 'com.google.ads.mediation:adcolony:4.1.0.0' //latest version 4.1.4.1 not compatible with firebase_admob 0.9.3+2
}

com.google.ads.mediation.adcolony releases

Answer 2

我没有降级 AdColony 中介适配器，而是通过手动编辑文件“flutter.pub-cache\hosted\pub.dartlang.org\firebase_admob-0.9.3+2\android\build.gradle "，因此它获取了最新版本的 Admob Android SDK：

android {
    dependencies {
        api 'com.google.firebase:firebase-ads:19.1.0'
    }
}

一个月前我在 Play Store 上发布了这个，对于一个拥有大约 100.000 MAU 的应用程序，到目前为止没有任何问题...
