觀衆網絡插頁式廣告/獎勵廣告在Unity上顯示Android崩潰

Question

我試圖在Android上顯示Facebook廣告。我在Android Studio項目中加入了Audience Network .jar。還將活動添加到Android Manifest。 這是的build.gradle：

android { 
 
    compileSdkVersion 25 
 
    buildToolsVersion "25.0.2" 
 
    testOptions { 
 
     unitTests.returnDefaultValues = true 
 
    } 
 
    defaultConfig { 
 
     minSdkVersion 15 
 
     targetSdkVersion 25 
 
     versionCode 1 
 
     versionName "1.0" 
 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
 
    } 
 
    buildTypes { 
 
     release { 
 
      minifyEnabled false 
 
      shrinkResources false 
 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
 
      debuggable false 
 
     } 
 
     debug { 
 
      debuggable true 
 
      jniDebuggable true 
 
      minifyEnabled false 
 
      shrinkResources false 
 
     } 
 
    } 
 
} 
 

 
dependencies { 
 
    // Required -- JUnit 4 framework 
 
    testCompile 'junit:junit:4.12' 
 
    // Optional -- Mockito framework 
 
    testCompile 'org.mockito:mockito-core:1.10.19' 
 
    compile 'com.google.android.gms:play-services:10.2.0' 
 
    compile files('libs/AudenceNetwork-4.24.0.jar') 
 
    compile 'com.android.support:appcompat-v7:25.0.0' 
 
    compile 'com.android.support:recyclerview-v7:25.0.0' 
 
}

這是我如何加載和顯示插頁片段和獎勵：

com.facebook.ads.InterstitialAd interstitial; 
 
com.facebook.ads.RewardedVideoAd rewarded 
 

 
public void loadInterstitial() { 
 
\t activity.runOnUiThread(new Runnable() { 
 
\t \t @Override 
 
\t \t public void run() { 
 
\t \t \t if (interstitial == null) { 
 
\t \t \t \t interstitial = new com.facebook.ads.InterstitialAd(activity, interstitialAd.getCode()); 
 
\t \t \t \t CustomFacebookInterstitialAdListener interestitialListener = new CustomFacebookInterstitialAdListener(AudienceNetworkAdProvider.this); 
 
\t \t \t \t interstitial.setAdListener(interestitialListener); 
 
\t \t \t } 
 
\t \t \t interstitial.loadAd(); 
 
\t \t } 
 
\t }); 
 
} 
 

 
public void showInterstitial() { 
 
\t if (isInterstitialAvailable()) { 
 
\t \t activity.runOnUiThread(new Runnable() { 
 
\t \t \t @Override 
 
\t \t \t public void run() { 
 
\t \t \t \t interstitial.show(); 
 
\t \t \t } 
 
\t \t }); 
 
\t } 
 
} 
 

 
public void loadRewardedAd() { 
 
\t activity.runOnUiThread(new Runnable() { 
 
\t \t @Override 
 
\t \t public void run() { 
 
\t \t \t if (rewarded == null) { 
 
\t \t \t \t rewarded = new com.facebook.ads.RewardedVideoAd(activity, rewardedAd.getCode()); 
 
\t \t \t \t CustomFacebookRewardedAdListener rewardedListener = new CustomFacebookRewardedAdListener(AudienceNetworkAdProvider.this); 
 
\t \t \t \t rewarded.setAdListener(rewardedListener); 
 
\t \t \t } 
 
\t \t \t rewarded.loadAd(); 
 
\t \t } 
 
\t }); 
 
} 
 

 
public void showRewardedAd() { 
 
\t if (isRewardedAdAvailable()) { 
 
\t \t activity.runOnUiThread(new Runnable() { 
 
\t \t \t @Override 
 
\t \t \t public void run() { 
 
\t \t \t \t rewarded.show(); 
 
\t \t \t } 
 
\t \t }); 
 
\t } 
 
}

的代碼在Android本地測試應用上運行良好。

我正在改編Unity，所以我可以在遊戲中展示廣告。但是，每次我想要顯示廣告時，它都會隨機崩潰應用程序。大多數時候，它讓我看到一個插頁式或獎勵，但之後崩潰。

這是怎麼我的插件/ Android的文件夾的樣子：

AndroidManifest.xml 
 
appcompat-v7-24.0.0 
 
myaudiencenetworkadapter.aar 
 
play-services-10.0.1.aar 
 
play-services-auth-10.0.1 
 
play-services-auth-base-10.0.1 
 
play-services-basement-10.0.1 
 
play-services-drive-10.0.1 
 
play-services-tasks-10.0.1 
 
recyclerview-v7-24.0.0 
 
support-v4-24.0.0

它崩潰時被調用com.facebook.ads.RewardedVideoAd.show（）方法。 這是崩潰日誌：

任何想法？

Answer 1

我終於解決了這個問題。 我正在銷燬來自我的Unity活動的onPause事件上的Audience Network廣告。每次顯示廣告時，onPause事件都會被調用，所以這是一團糟。

Answer 2

在Android Studio中有一個官方的Unity Facebook插件時，你不應該搞Java和Facebook jar。有關如何設置它的說明，請參閱此link，並獲取實際SDK的here。

當您下載插件，你會發現InterstitialAdScene，RewardedVideoAdScene和包含的範例代碼，您應該加載InterstitialAdScene場景，因爲這是你在找什麼NativeAdScene場景。

下面是從InterstitialAdTest.cs C＃插頁式廣告例子文件中AudienceNetwork \的Samples \間質性文件夾。

public class InterstitialAdTest : MonoBehaviour 
{ 

    private InterstitialAd interstitialAd; 
    private bool isLoaded; 

    // UI elements in scene 
    public Text statusLabel; 

    // Load button 
    public void LoadInterstitial() 
    { 
     this.statusLabel.text = "Loading interstitial ad..."; 

     // Create the interstitial unit with a placement ID (generate your own on the Facebook app settings). 
     // Use different ID for each ad placement in your app. 
     InterstitialAd interstitialAd = new InterstitialAd ("YOUR_PLACEMENT_ID"); 
     this.interstitialAd = interstitialAd; 
     this.interstitialAd.Register (this.gameObject); 

     // Set delegates to get notified on changes or when the user interacts with the ad. 
     this.interstitialAd.InterstitialAdDidLoad = (delegate() { 
      Debug.Log ("Interstitial ad loaded."); 
      this.isLoaded = true; 
      this.statusLabel.text = "Ad loaded. Click show to present!"; 
     }); 
     interstitialAd.InterstitialAdDidFailWithError = (delegate(string error) { 
      Debug.Log ("Interstitial ad failed to load with error: " + error); 
      this.statusLabel.text = "Interstitial ad failed to load. Check console for details."; 
     }); 
     interstitialAd.InterstitialAdWillLogImpression = (delegate() { 
      Debug.Log ("Interstitial ad logged impression."); 
     }); 
     interstitialAd.InterstitialAdDidClick = (delegate() { 
      Debug.Log ("Interstitial ad clicked."); 
     }); 

     // Initiate the request to load the ad. 
     this.interstitialAd.LoadAd(); 
    } 

    // Show button 
    public void ShowInterstitial() 
    { 
     if (this.isLoaded) { 
      this.interstitialAd.Show(); 
      this.isLoaded = false; 
      this.statusLabel.text = ""; 
     } else { 
      this.statusLabel.text = "Ad not loaded. Click load to request an ad."; 
     } 
    } 

    void OnDestroy() 
    { 
     // Dispose of interstitial ad when the scene is destroyed 
     if (this.interstitialAd != null) { 
      this.interstitialAd.Dispose(); 
     } 
     Debug.Log ("InterstitialAdTest was destroyed!"); 
    } 

    // Next button 
    public void NextScene() 
    { 
     SceneManager.LoadScene ("AdViewScene"); 
    } 
}
