添加Admob SDwww.devze.comK
最近公司的项目新接入了Admob广告SDK,本文介绍下Admob插屏、激励视频、Banner等三种广告的接入方法。
官方接入文档
(1)在app module下的build.gradle中添加代码,如下:
dependencies { implementation 'com.google.android.gms:play-services-ads:21.4.0' }
(2)在AndroidManifest中添加代码,如下:
<?XML version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"> <uses-permission android:name="android.permission.ACCEphpSS_NETWORK_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <application> <meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/> </application> </manifest>
初始化SDK
通过MobileAds
的initialize
方法进行初始化,代码如下:
class AdmobExampleActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) MobileAds.initialize(this, object : OnInitializationCompleteListener { override fun onInitializationComplete(initializationStatus: InitializationStatus) { val readyAdapter = initializationStatus.adapterStatusMap.entries.find { // 判断适配器初始化的状态 // 准备就绪 AdapterStatus.State.READY // 没准备好 AdapterStatus.State.NOT_READY it.value.initializationState == AdapterStatus.State.READY } // 有任意一种适配器初始化成功就可以开始加载广告 if (readyAdapter != null) { http://www.devze.com // 适配器的名称 val adapterName = readyAdapter.key } } }) } }
插屏广告
插屏广告的加载、展示等代码如下:
class AdmobExampleActivity : AppCompatActivity() { private lateinit var binding: LayoutAdmobExampleActivityBinding private var interstitialAd: InterstitialAd? = null // 插屏广告加载状态的回调 private val interstitialAdLoadCallback = object : InterstitialAdLoadCallback() { override fun onAdLoaded(interstitialAd: InterstitialAd) { super.onAdLoaded(interstitialAd) // 加载成功 this@AdmobExampleActivity.interstitialAd = interstitialAd // 设置广告事件回调 this@AdmobExampleActivity.interstitialAd?.fullScreenContentCallback = interstitialAdCallback // 显示插屏广告 this@AdmobExampleActivity.interstitialAd?.show(this@AdmobExampleActivity) } override fun onAdFailedToLoad(loadAdError: LoadAdError) { super.onAdFailedToLoad(loadAdError) // 加载失败 } } // 插屏广告相关事件回调 private val interstitialAdCallback = object : FullScreenContentCallback() { override fun onAdImpression() { super.onAdImpression() // 被记录为展示成功时调用 } override fun onAdShowedFullScreenContent() { super.onAdShowedFullScreenContent() // 显示时调用 } override fun onAdClicked() { super.onAdClicked() 开发者_JAVA教程 // 被点击时调用 } override fun onAdDismissedFullScreenContent() { super.onAdDismissedFullScreenContent() // 隐藏时调用,此时销毁当前的插屏广告对象,重新加载插屏广告 interstitialAd = null loadInterstitialAd() } override fun onAdFailedToShowFullScreenContent(adError: AdError) { super.onAdFailedToShowFullScreenContent(adError) // 展示失败时调用,此时销毁当前的插屏广告对象,重新加载插屏广告 interstitialAd = null loadInterstitialAd() } } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) MobileAds.initialize(this, object : OnInitializationCompleteListener { override fun onInitializationComplete(initializationStatus: InitializationStatus) { ... loadInterstitialAd() } }) } private fun loadInterstitialAd() { // adUnitId为Admob后台创建的插屏广告的id InterstitialAd.load(this, "adUnitId", AdRequest.Builder().build(), interstitialAdLoadCallback) } }
激励视频广告
激励视频广告的加载、展示等代码如下:
class AdmobExampleActivity : AppCompatActivity() { private lateinit var binding: LayoutAdmobExampleActivityBinding private var rewardedAd: RewardedAd? = null private val rewardedAdLoadCallback = object : RewardedAdLoadCallback() { override fun onAdLoaded(rewardedAd: RewardedAd) { super.onAdLoaded(rewardedAd) // 加载成功 this@AdmobExampleActivity.rewardedAd = rewardedAd // 设置广告事件回调 this@AdmobExampleActivity.rewardedAd?.fullScreenContentCallback = rewardedVideoAdCallback // 展示广告 this@AdmobExampleActivity.rewardedAd?.show(this@AdmobExampleActivity, rewardedVideoAdEarnedCallback) } override fun onAdFailedToLoad(loadAdError: LoadAdError) { super.onAdFailedToLoad(loadAdError) // 加载失败 } } private val rewardedVideoAdCallback = object : FullScreenContentCallback() { override fun onAdImpression() { super.onAdImpression() // 被记录为展编程示成功时调用 } override fun onAdShowedFullScreenContent() { super.onAdShowedFullScreenContent() // 显示时调用 } override fun onAdClicked() { super.onAdClicked() // 被点击时调用 } override fun onAdDismissedFullScreenContent() { super.onAdDismissedFullScreenContent() // 隐藏时调用,此时销毁当前的激励视频广告对象,重新加载激励视频广告 rewardedAd = null loadRewardedVideoAd() } override fun onAdFailedToShowFullScreenContent(adError: AdError) { super.onAdFailedToShowFullScreenContent(adError) // 展示失败时调用,此时销毁当前的激励视频广告对象,重新加载激励视频广告 rewardedAd = null loadRewardedVideoAd() } } private val rewardedVideoAdEarnedCallback = OnUserEarnedRewardListener { // 用户获得奖励回调 // 奖励的类型 val type = it.type // 奖励的金额 val amount = it.amount } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) MobileAds.initialize(this, object : OnInitializationCompleteListener { override fun onInitializationComplete(initializationStatus: InitializationStatus) { ... loadRewardedVideoAd() } }) binding.btnShowInterstitialAd.setOnClickListener { showInterstitialAd() } } private fun loadRewardedVideoAd() { // adUnitId为Admob后台创建的激励视频广告的id RewardedAd.load(this, "adUnitId", AdRequest.Builder().build(), rewardedAdLoadCallback) } }
Banner广告
Banner广告的加载、展示等代码如下:
class AdmobExampleActivity : AppCompatActivity() { private lateinit var binding: LayoutAdmobExampleActivityBinding private var bannerAdView: AdView? = null private val bannerListener = object : AdListener() { override fun onAdLoaded() { super.onAdLoaded() // 广告加载成功 } override fun onAdFailedToLoad(loadAdError: LoadAdError) { super.onAdFailedToLoad(loadAdError) // 广告加载失败 } override fun onAdImpression() { super.onAdImpression() // 被记录为展示成功时调用 } override fun onAdClicked() { super.onAdClicked() // 被点击时调用 } override fun onAdOpened() { super.onAdOpened() etArBfXz// 广告落地页打开时调用 } override fun onAdClosed() { super.onAdClosed() // 广告落地页关闭时调用 } } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) MobileAds.initialize(this, object : OnInitializationCompleteListener { override fun onInitializationComplete(initializationStatus: InitializationStatus) { createBannerAdView() } }) } private fun createBannerAdView() { // 获取页面的根布局 val rootView = findViewById<FrameLayout>(android.R.id.content) bannerAdView = AdView(this) bannerAdView?.run { // 设置Banner的尺寸 setAdSize(AdSize.BANNER) // adUnitId为Admob后台创建的Banner广告的id adUnitId = "adUnitId" // 设置广告事件回调 adListener = bannerListener val bannerViewLayoutParams = FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT) // 设置显示在页面的底部中间 bannerViewLayoutParams.gravity = Gravity.BOTTOM or Gravity.CENTER_HORIZONTAL layoutParams = bannerViewLayoutParams alpha = 0f // 把 Banner Ad 添加到根布局 rootView.addView(this) //加载广告 loadAd(AdRequest.Builder().build()) } } }
测试广告
注意,Admob官方声明了在开发过程中启用测试广告非常重要,这样您就可以在不向 Google 广告客户收费的情况下点击广告。如果您在非测试模式下点击过多广告,可能会导致您的帐号因无效活动而被举报。
想要测试广告的效果,可以通过两种方式。
- 使用谷歌提供的测试id
谷歌提供了一整套测试id,使用这套id可以获取Admob的测试广告。
// 测试应用id ApplicationId:"ca-app-pub-3940256099942544~3347511713" // 测试插屏广告id InterstitialUnitId:"ca-app-pub-3940256099942544/1033173712" // 测试激励视频广告id RewardedVideoUnitId:"ca-app-pub-3940256099942544/5224354917" // 测试Banner广告id BannerUnitId:"ca-app-pub-3940256099942544/6300978111"
- 使用自己应用的id,并注册测试设备
如果想要使用自己应用的id进行测试,可以通过注册测试设备来拉取测试广告。
集成好SDK后,安装App,查看tag为Ads的日志,可以看到测试设备id,如下:
获取测试设备id后,通过代码注册测试设备,如下:
MobileAds.setRequestConfiguration(RequestConfiguration.Builder() .setTestDeviceIds(arrayListOf("deviceId")) .build())
注册好测试设备后重新安装App即可。
示例
整合之后,使用Admob提供的测试设备做了个示例demo。

ExampleDemo gitee
效果如图:
