小编Lak*_*hmi的帖子

我已按照此链接在我的应用中集成广告.但它显示了这个错误:

这是我的build.gradle:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"





defaultConfig {
    applicationId "com.example.personal.numbermania"
    minSdkVersion 10
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
}
buildTypes {
    debug
            {
                debuggable true
            }
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
    compile 'com.google.firebase:firebase-ads:9.6.0'

}

}

广告没有出现在真实的设备中.请帮助我这是我更新类路径错误后的 错误
