使用 Android Studio 3.2 或更高版本
确保您应用的 build 文件使用以下值:
minSdkVersion
为 16
或更高版本compileSdkVersion
为 28
或更高版本1,在您的项目级 build.gradle
文件中,同时在 buildscript
和 allprojects
两个部分中添加
buildscript {
repositories {
google()
mavenCentral()
}
}
allprojects {
repositories {
google()
mavenCentral()
}
}
2,将 Google 移动广告 SDK 的依赖项添加到您的模块的应用级 Gradle 文件,通常为 app/build.gradle:
dependencies {
implementation 'com.google.android.gms:play-services-ads:21.0.0'
}
3,将您的 AdMob 应用 ID(可在 AdMob 界面中找到)添加到应用的 AndroidManifest.xml
文件中。为此,请添加包含 android:name="com.google.android.gms.ads.APPLICATION_ID"
的 <meta-data>
代码。您可以在 AdMob 界面中找到您的应用 ID。对于 android:value
,请插入您自己的 AdMob 应用 ID,并用英文引号括起来。
测试ID:ca-app-pub-3940256099942544~3347511713
注意:开发工程一定要使用测试ID,不要使用线上ID,否则可能导致线上admob广告流量无效,最严重导致封号!
4,初始化广告和预加载激励视频
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;

}
});
}else{
showJiangli("广告拉取中,请稍候再试");
loadJiliAd();
}
}
private void showJiangli(String msg){
Toast.makeText(this,msg,Toast.LENGTH\_SHORT).show();

// 在为广告记录点击时调用。
Log.d("TAG", "Ad was clicked.");
}
@Override
public void onAdDismissedFullScreenContent() {
// 当广告被关闭时调用.
// 将广告引用设置为 null,这样您就不会再次展示广告。
Log.d("TAG", "Ad dismissed fullscreen content.");
mRewardedAd = null;

}
}
6,webAppInterface类
public class WebAppInterface {
Activity mContext;
Handler mHandler;
/\*\*
\* Instantiate the interface and set the context
\*/
WebAppInterface(Activity c,Handler r) {
mContext = c;
mHandler = r;
}
/\*\*
\* js调用Android的函数
\*/
@JavascriptInterface
public void startFunction() {
Toast.makeText(mContext,"我是安卓原生的弹窗",Toast.LENGTH\_SHORT).show();
//调用激励视频广告
Message msg = new Message();
msg.what = 0;
mHandler.sendMessage(msg);
}
/\*\*
\* js调用Android的函数并给Android原生传递一个参数
\*/
@JavascriptInterface
public void startFunction(String arg) {
Toast.makeText(mContext,arg,Toast.LENGTH\_SHORT).show();
}
}
7,html调用激励奖励
