我试图在Android上展示Facebook广告。我在我的Android Studio项目中包含了Audience Network .jar。还将活动添加到Android Manifest。 这是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'
}
这是关于我如何加载和显示插页式广告并获得奖励的摘录：
com.facebook.ads.InterstitialAd interstitial;
com.facebook.ads.RewardedVideoAd rewarded
public void loadInterstitial() {
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
if (interstitial == null) {
interstitial = new com.facebook.ads.InterstitialAd(activity, interstitialAd.getCode());
CustomFacebookInterstitialAdListener interestitialListener = new CustomFacebookInterstitialAdListener(AudienceNetworkAdProvider.this);
interstitial.setAdListener(interestitialListener);
}
interstitial.loadAd();
}
});
}
public void showInterstitial() {
if (isInterstitialAvailable()) {
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
interstitial.show();
}
});
}
}
public void loadRewardedAd() {
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
if (rewarded == null) {
rewarded = new com.facebook.ads.RewardedVideoAd(activity, rewardedAd.getCode());
CustomFacebookRewardedAdListener rewardedListener = new CustomFacebookRewardedAdListener(AudienceNetworkAdProvider.this);
rewarded.setAdListener(rewardedListener);
}
rewarded.loadAd();
}
});
}
public void showRewardedAd() {
if (isRewardedAdAvailable()) {
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
rewarded.show();
}
});
}
}
该代码适用于Android原生测试应用程序。
我正在改编Unity，因此我可以在游戏中展示广告。但是，每当我想要显示广告时，它会随机崩溃应用程序。大多数时候，它让我看到一个插页式广告或奖励，但在那之后崩溃。
这就是我的插件/ Android文件夹的样子：
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
调用 com.facebook.ads.RewardedVideoAd.show（）方法时崩溃。 这是崩溃的日志：

有什么想法吗？

当有一个官方的Unity Facebook插件时，你不应该在Android Studio中弄乱Java和Facebook jar。有关如何设置的说明，请参阅此link;有关获取实际SDK的信息，请参见here。
下载插件时，您会发现 InterstitialAdScene ， RewardedVideoAdScene 和 NativeAdScene 场景，其中包含您应加载 InterstitialAdScene的示例代码场景，因为那是你想要的。
以下是 AudienceNetwork \ Samples \ Interstitial 文件夹中 InterstitialAdTest.cs 文件的C＃插页式广告示例。
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");
}
}

我终于解决了这个问题。 我正在从Unity活动中销毁onPause事件中的Audience Network广告。每次显示广告时，都会调用onPause事件，因此它很乱。
