我在我的某个活动中显示原生应用安装广告视图时遇到问题。 Google展示了原生广告的实施： https://github.com/googleads/googleads-mobile-android-examples/tree/master/admob/NativeExample我已将代码集成到我的项目中。这是我的gradle文件：
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.somepack.tests"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.google.android.gms:play-services-ads:9.2.0'
compile 'com.google.firebase:firebase-ads:9.0.0'
}
apply plugin: 'com.google.gms.google-services'
我还在我的根gradle文件中添加了相同的代码：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
mavenLocal()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenLocal()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
我尝试使用Google的应用ID和单元ID运行应用，所有内容似乎都在运行。当我将应用ID和单位ID更改为我的值时，它会一直说“无法加载原生广告”，错误代码为0.

我认为它没有显示广告，因为我的apk是调试版，也尝试过发布版。但没机会。我错过了Admob面板上的设置或我需要实现的任何代码吗？我很感激任何帮助。
P.S：我上面写的代码只是一个试用版，我在我的真实应用程序中有相同的代码，在Play商店中，但无法成功。
答案 0 :(得分：0)
我认为您可以从无法为其提供服务的广告单元中请求原生高级广告。您和您的应用是否已被接受进入AdMob原生广告高级版的测试版？如果没有，您将无法创建原生高级广告单元，这意味着您在上面提供的代码只能在测试模式下使用。
目前，AdMob提供两种不同类型的原生广告，即Advanced和Express（a guide that explains the difference）。 Native Express对所有AdMob发布商来说都更新，更容易，更开放，所以如果您还没有尝试过，我建议您试一试：
