Banner / Interstitial / Native等中介實作皆在TAmediaCustomEvent

Proguard

下列mediation class, 開發商於proguard中須進行保護, 避免混淆後找不到該class造成AdMob SDK拋出錯誤訊息

Could not load custom event implementation class: com.taiwanmobile.pt.adp.mediation.TAmediaNative, trying Adapter implementation class.

-keep class com.taiwanmobile.pt.adp.mediation.** {
    public protected <fields>;
    public protected <methods>;
}

Developer Sample Code

Banner

1. 在MainActivity.kt中輸入AdUnit Id

   companion object {
       private const val ADUNIT_ID_BANNER_320x50 = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_BANNER_300x250 = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_SMART_BANNER = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_INTERSTITIAL = "{AdMob Interstitial AdUnit Id}"
       private const val ADUNIT_ID_NATIVE = "{AdMob Native AdUnit Id}"
       const val KEY_ADUNITID = "adUnitId"
       const val KEY_ADSIZE = "adSize"
   }

2. 在layout檔案中加入可放置廣告的RelativeLayout(※僅供參考,開發者可依照自訂的layout進行配置使用)

   <RelativeLayout
       android:id="@+id/adContainer"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_centerHorizontal="true"
       android:layout_alignParentBottom="true">
   </RelativeLayout>

3. BannerActivity 程式加入Banner的宣告, 設定AdUnitId與AdSize

   class BannerActivity : AppCompatActivity() {
       private var adView: AdView? = null
       override fun onCreate(savedInstanceState: Bundle?) {
           super.onCreate(savedInstanceState)
           setContentView(R.layout.activity_banner)
           val adContainer = findViewById<View>(R.id.adContainer) as RelativeLayout
           val args = intent.extras
           if (args != null) {
               val adUnitId = args.getString(MainActivity.KEY_ADUNITID)
               val adSize: AdSize = when (args.getString(MainActivity.KEY_ADSIZE)) {
                   BANNER_320x50 -> {
                       AdSize.BANNER
                   }
                   BANNER_300x250 -> {
                       AdSize.MEDIUM_RECTANGLE
                   }
                   else -> {
                       val displayMetrics = resources.displayMetrics
                       val dpWidth = (displayMetrics.widthPixels / displayMetrics.density).toInt()
                       AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(
                           this,
                           dpWidth
                       )
                   }
               } 

               // Banner initial
               adUnitId?.let {
                   val request = AdRequest.Builder().build()
                   adView = AdView(this@BannerActivity)
                   adView?.adUnitId = it
                   adView?.adSize = adSize
                   adView?.adListener = AdListenerImpl()
                   adView?.loadAd(request)
                   // add view into layout
                   adContainer.addView(adView)
               }
           }
       }
}

Interstitial

1. 在MainActivity.kt中輸入AdUnit Id

   companion object {
       private const val ADUNIT_ID_BANNER_320x50 = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_BANNER_300x250 = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_SMART_BANNER = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_INTERSTITIAL = "{AdMob Interstitial AdUnit Id}"
       private const val ADUNIT_ID_NATIVE = "{AdMob Native AdUnit Id}"
       const val KEY_ADUNITID = "adUnitId"
       const val KEY_ADSIZE = "adSize"
   }

2. InterstitialActivity 程式加入Interstitial的宣告, 設定AdUnitId

class InterstitialActivity : AppCompatActivity() {

    private var interstitialAd: InterstitialAd? = null
    private var adUnitId: String? = null
    private lateinit var binding: ActivityInterstitialBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityInterstitialBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)

        val args = intent.extras
        if (args != null) {
            adUnitId = args.getString(MainActivity.KEY_ADUNITID)
        }
    }

    // triggered in activity_int.xml
    fun fireAd(v: View?) {
        adUnitId?.let {
            val adRequest = AdRequest.Builder().build()
            InterstitialAd.load(this, it, adRequest, object : InterstitialAdLoadCallback() {
                override fun onAdLoaded(interstitialAd: InterstitialAd) {
                    this@InterstitialActivity.interstitialAd = interstitialAd
                    Toast.makeText(
                        baseContext,
                        "onAdLoaded(interstitial) invoked!!",
                        Toast.LENGTH_SHORT
                    ).show()
                    interstitialAd.show(this@InterstitialActivity)
                }

                override fun onAdFailedToLoad(loadAdError: LoadAdError) {
                    Toast.makeText(
                        baseContext,
                        loadAdError.message,
                        Toast.LENGTH_SHORT
                    ).show()
                    interstitialAd = null
                }
            })
        }
    }
}

Native

1. 在MainActivity.kt中輸入AdUnit Id

   companion object {
       private const val ADUNIT_ID_BANNER_320x50 = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_BANNER_300x250 = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_SMART_BANNER = "{AdMob Banner AdUnit Id}"
       private const val ADUNIT_ID_INTERSTITIAL = "{AdMob Interstitial AdUnit Id}"
       private const val ADUNIT_ID_NATIVE = "{AdMob Native AdUnit Id}"
       const val KEY_ADUNITID = "adUnitId"
       const val KEY_ADSIZE = "adSize"
   }

2. NativeActivity的layout如下, 在layout檔案中加入可放置原生廣告的nativeContainer(※這裡以FrameLayout為例,開發者可依照自訂的layout進行配置使用)

   <LinearLayout
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingBottom="@dimen/activity_vertical_margin"
       android:paddingLeft="@dimen/activity_horizontal_margin"
       android:paddingRight="@dimen/activity_horizontal_margin"
       android:paddingTop="@dimen/activity_vertical_margin"
       android:orientation="vertical">
   <FrameLayout
           android:id="@+id/native_container"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:layout_marginTop="@dimen/activity_vertical_margin" />
   </LinearLayout>

3. 準備廣告佈局native_ad.xml, 使用AdMob com.google.android.gms.ads.nativead.NativeAdView

   <com.google.android.gms.ads.nativead.NativeAdView
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:orientation="vertical">
           <LinearLayout
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:layout_gravity="center"
               android:background="#FFFFFF"
               android:minHeight="50dp"
               android:orientation="vertical">
               <LinearLayout
                   android:layout_width="match_parent"
                   android:layout_height="wrap_content"
                   android:orientation="vertical"
                   android:paddingLeft="20dp"
                   android:paddingTop="3dp"
                   android:paddingRight="20dp">
                   <LinearLayout
                       android:layout_width="match_parent"
                       android:layout_height="wrap_content"
                       android:orientation="horizontal">
                       <ImageView
                           android:id="@+id/ad_app_icon"
                           android:layout_width="40dp"
                           android:layout_height="40dp"
                           android:adjustViewBounds="true"
                           android:paddingEnd="5dp"
                           android:paddingRight="5dp"
                           android:paddingBottom="5dp" />
                       <LinearLayout
                           android:layout_width="match_parent"
                           android:layout_height="wrap_content"
                           android:orientation="vertical">
                           <TextView
                               android:id="@+id/ad_headline"
                               android:layout_width="match_parent"
                               android:layout_height="wrap_content"
                               android:textColor="#0000FF"
                               android:textSize="16sp"
                               android:textStyle="bold" />
                       </LinearLayout>
                   </LinearLayout>
                   <LinearLayout
                       android:layout_width="match_parent"
                       android:layout_height="wrap_content"
                       android:orientation="vertical">
                   <TextView
                       android:id="@+id/ad_body"
                       android:layout_width="wrap_content"
                       android:layout_height="wrap_content"
                       android:layout_marginEnd="20dp"
                       android:layout_marginRight="20dp"
                       android:textSize="12sp" />
                   <com.google.android.gms.ads.nativead.MediaView
                       android:id="@+id/ad_media"
                       android:layout_width="250dp"
                       android:layout_height="175dp"
                       android:layout_gravity="center_horizontal"

                   </LinearLayout>
               </LinearLayout>
           </LinearLayout>
   </com.google.android.gms.ads.nativead.NativeAdView>

4. 使用AdMob AdLoader載入原生廣告

當AdLoader取得原生廣告時, 產出(inflate)原生廣告佈局native_ad.xml並進行NativeAdView物件填充(population), 詳情可參考下方populateNativeAdView()

NativeAdView填充下列屬性: headline, body, call to action, icon, mediaView等資訊

填充後將native_ad.xml物件加入nativeContainer

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityNativeBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)

        val args = intent.extras
        args?.let {
            val adUnitId = args.getString(MainActivity.KEY_ADUNITID) ?: ""
            val adLoader = AdLoader.Builder(this, adUnitId)
                .forNativeAd { ad: NativeAd ->
                    nativeAd = ad
                    val adLayout = NativeAdBinding.inflate(layoutInflater)
                    populateNativeAdView(ad, adLayout)
                    binding.nativeContainer.removeAllViews()
                    binding.nativeContainer.addView(adLayout.root)

                    // If this callback occurs after the activity is destroyed, you
                    // must call destroy and return or you may get a memory leak.
                    // Note `isDestroyed` is a method on Activity.

                    if (isDestroyed) {
                        ad.destroy()
                        return@forNativeAd
                    }
                }
                .withAdListener(object : AdListener() {
                    override fun onAdFailedToLoad(adError: LoadAdError) {
                        Toast.makeText(this@NativeActivity, "onAdFailedToLoad", Toast.LENGTH_LONG)
                            .show()
                    }

                    override fun onAdClicked() {
                        super.onAdClicked()
                        Toast.makeText(this@NativeActivity, "onAdClicked", Toast.LENGTH_LONG)
                            .show()
                    }

                    override fun onAdImpression() {
                        super.onAdImpression()
                        Toast.makeText(this@NativeActivity, "onAdImpression", Toast.LENGTH_LONG)
                            .show()
                    }
                })
                .withNativeAdOptions(
                    NativeAdOptions.Builder()
                        // Methods in the NativeAdOptions.Builder class can be
                        // used here to specify individual options settings.
                        .build()
                )
                .build()
            adLoader.loadAd(AdRequest.Builder().build())
        }
    }

    /**
     * Populates a [NativeAdView] object with data from a given [NativeAd].
     *
     * @param nativeAd the object containing the ad's assets
     * @param viewBinding the view binding object [NativeAdBinding] contains the [NativeAdView]
     */
    private fun populateNativeAdView(nativeAd: NativeAd, viewBinding: NativeAdBinding) {

        // fetch NativeAdView from NativeAdBinding
        val nativeAdView: NativeAdView = viewBinding.root

        // headline
        if (nativeAd.headline == null) {
            viewBinding.adHeadline.visibility = View.INVISIBLE
        } else {
            viewBinding.adHeadline.visibility = View.VISIBLE
            viewBinding.adHeadline.text = nativeAd.headline
            nativeAdView.headlineView = viewBinding.adHeadline
        }

            viewBinding.adAppIcon.visibility = View.GONE
        } else {
            nativeAd.icon?.drawable?.let {
                viewBinding.adAppIcon.setImageDrawable(it)
                viewBinding.adAppIcon.visibility = View.VISIBLE
                nativeAdView.iconView = viewBinding.adAppIcon
            }
        }
        // mediaView
        nativeAdView.mediaView = viewBinding.adMedia
        nativeAdView.setNativeAd(nativeAd)
    }

5. 設計架構圖

- 藍色為TAmedia SDK原生廣告類別, 黃色為AdMob SDK原生廣告類別

- 開發者僅需在native_ad.xml使用AdMob SDK, 其他則由TAmedia mediation實作負責

- 佈局中如果有發現AdMob SDK MediaView, TAmedia SDK TWMMediaView則會主動覆蓋至上面, 負責顯示影音廣告
