使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
借助自定义事件,您可以为支持的广告联盟以外的广告联盟添加广告瀑布流中介。为此,您可以为要集成的广告联盟实现自定义事件适配器。
如需查看完整的示例自定义事件项目,请访问我们的 GitHub 代码库。
前提条件
您必须先将以下广告格式之一集成到您的应用中,然后才能创建自定义事件:
在界面中创建自定义事件
您必须先在 AdMob 界面中创建自定义事件。请参阅添加自定义事件中的说明。
您需要提供以下信息:
- 类名称
实现自定义事件适配器的类的完全限定名称,例如,com.google.ads.mediation.sample.customevent.SampleCustomEvent
。我们建议的最佳做法是,为所有自定义事件广告格式使用同一适配器类。
- 标签
定义广告来源的唯一名称。
- 参数
传递给自定义事件适配器的可选字符串参数。
初始化适配器
Google 移动广告 SDK 初始化时,系统会针对在 AdMob 界面中为应用配置的所有支持的第三方适配器和自定义事件调用 initialize()
。您可以使用此方法对自定义事件所需的第三方 SDK 执行任何必要的设置或初始化操作。
Java
package com.google.ads.mediation.sample.customevent;
import com.google.android.gms.ads.mediation.Adapter;
import com.google.android.gms.ads.mediation.InitializationCompleteCallback;
import com.google.android.gms.ads.mediation.MediationConfiguration;
public class SampleAdNetworkCustomEvent extends Adapter {
private static final String SAMPLE_AD_UNIT_KEY = "parameter";
@Override
public void initialize(Context context,
InitializationCompleteCallback initializationCompleteCallback,
List<MediationConfiguration> mediationConfigurations) {
// This is where you will initialize the SDK that this custom
// event is built for. Upon finishing the SDK initialization,
// call the completion handler with success.
initializationCompleteCallback.onInitializationSucceeded();
}
}
Kotlin
package com.google.ads.mediation.sample.customevent
import com.google.android.gms.ads.mediation.Adapter
import com.google.android.gms.ads.mediation.InitializationCompleteCallback
import com.google.android.gms.ads.mediation.MediationConfiguration
class SampleCustomEvent : Adapter() {
private val SAMPLE_AD_UNIT_KEY = "parameter"
override fun initialize(
context: Context,
initializationCompleteCallback: InitializationCompleteCallback,
mediationConfigurations: List<MediationConfiguration>
) {
// This is where you will initialize the SDK that this custom
// event is built for. Upon finishing the SDK initialization,
// call the completion handler with success.
initializationCompleteCallback.onInitializationSucceeded()
}
}
报告版本号
所有自定义事件都必须向 Google 移动广告 SDK 报告自定义事件适配器本身的版本,以及与该自定义事件对接的第三方 SDK 的版本。报告版本时使用的是 VersionInfo
对象:
Java
package com.google.ads.mediation.sample.customevent;
public class SampleCustomEvent extends Adapter {
@Override
public VersionInfo getVersionInfo() {
String versionString = new VersionInfo(1, 2, 3);
String[] splits = versionString.split("\\.");
if (splits.length >= 4) {
int major = Integer.parseInt(splits[0]);
int minor = Integer.parseInt(splits[1]);
int micro = Integer.parseInt(splits[2]) * 100 + Integer.parseInt(splits[3]);
return new VersionInfo(major, minor, micro);
}
return new VersionInfo(0, 0, 0);
}
@Override
public VersionInfo getSDKVersionInfo() {
String versionString = SampleAdRequest.getSDKVersion();
String[] splits = versionString.split("\\.");
if (splits.length >= 3) {
int major = Integer.parseInt(splits[0]);
int minor = Integer.parseInt(splits[1]);
int micro = Integer.parseInt(splits[2]);
return new VersionInfo(major, minor, micro);
}
return new VersionInfo(0, 0, 0);
}
}
Kotlin
package com.google.ads.mediation.sample.customevent
class SampleCustomEvent : Adapter() {
override fun getVersionInfo(): VersionInfo {
val versionString = VersionInfo(1,2,3).toString()
val splits: List<String> = versionString.split("\\.")
if (splits.count() >= 4) {
val major = splits[0].toInt()
val minor = splits[1].toInt()
val micro = (splits[2].toInt() * 100) + splits[3].toInt()
return VersionInfo(major, minor, micro)
}
return VersionInfo(0, 0, 0)
}
override fun getSDKVersionInfo(): VersionInfo {
val versionString = VersionInfo(1,2,3).toString()
val splits: List<String> = versionString.split("\\.")
if (splits.count() >= 3) {
val major = splits[0].toInt()
val minor = splits[1].toInt()
val micro = splits[2].toInt()
return VersionInfo(major, minor, micro)
}
return VersionInfo(0, 0, 0)
}
}
