无法解决：firebase-ads：15.0.1：15.0.0

Question

我想使用admob通过我的应用获利。

当我使用firebase中可用的admob选项时，它要求我添加以下依赖项'com.google.firebase:firebase-ads:15.0.1:15.0.0' 但是在构建gradle之后，它给了我Failed to resolve: firebase-ads-15.0.0这个错误，所以我使用了'com.google.firebase:firebase-ads:12.0.1'，效果很好，但与此同时我看不到广告。这些是我的依赖项：

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:support-v4:26.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.daimajia.easing:library:2.0@aar'
    implementation 'com.daimajia.androidanimations:library:2.3@aar'
    implementation 'com.google.android.gms:play-services:12.0.1'
    testImplementation 'junit:junit:4.12'
    implementation 'com.google.firebase:firebase-core:12.0.1'
    //implementation 'com.google.firebase:firebase-ads:12.0.1'
    //implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.google.firebase:firebase-ads:15.0.1:15.0.0'
}

这是我的项目级别gradle文件

 buildscript {
 repositories {
    google()
    jcenter()
 }
 dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    //classpath 'com.google.gms:google-services:4.0.1'
    classpath 'com.google.android.gms:strict-version-matcher-plugin:1.0.0'
    classpath 'com.google.gms:google-services:4.1.0'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
 }
 }

allprojects {
repositories {
    google()
    jcenter()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

Answer 1

Firebase 核心和广告的编译版本应相同 试试这个版本 16.0.4

它看起来像这样：

implementation com.google.firebase:firebase-core:16.0.4

implementation 'com.google.firebase:firebase-ads:16.0.4'

Answer 2

更改行：

       implementation 'com.google.firebase:firebase-ads:15.0.1:15.0.0'

到

       implementation 'com.google.firebase:firebase-ads:15.0.1'
