在 Android 中实现奖励广告

对观看广告的用户进行奖励可以增加用户参与度，从而带来更高收入。例如，游戏可以用游戏币, 消耗品, 额外生命数量或经验倍增法宝来奖励用户。如需了解如何有效设计奖励广告的更多信息，请参阅变现策略指南。

要奖励用户看完视频广告，请使用 IUnityAdsShowListener.onUnityAdsShowComplete 监听器回调方法的 UnityAdsShowCompletionState 结果来检查用户是否看完广告并应该获得奖励。

奖励视频广告按钮

使用按钮让玩家选择观看广告是奖励视频广告的常见实现方式。可使用以下示例代码来创建奖励广告按钮。只要事先加载了广告，就会在按下广告按钮时展示广告。有关配置按钮的信息，请参阅有关按钮的 Android 开发者文档。

实现按钮后，请添加一个包含以下代码的脚本，其中 showAdButton 是 View 中配置的按钮：

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

import androidx.appcompat.app.AppCompatActivity;

import com.unity3d.ads.IUnityAdsLoadListener;
import com.unity3d.ads.IUnityAdsShowListener;
import com.unity3d.ads.UnityAdsShowOptions;
import com.unity3d.ads.example.R;

import com.unity3d.ads.IUnityAdsInitializationListener;
import com.unity3d.ads.UnityAds;

public class RewardedAdButton extends AppCompatActivity implements IUnityAdsInitializationListener  {

  private String unityGameID = "1234567";
  private Boolean testMode = true;
  private String adUnitId = "rewardedVideo";
  private Button rewardedButton;

  private IUnityAdsLoadListener loadListener = new IUnityAdsLoadListener() {
    @Override
    public void onUnityAdsAdLoaded(String placementId) {
      UnityAds.show((Activity)getApplicationContext(), adUnitId, new UnityAdsShowOptions(), showListener);
    }

    @Override
    public void onUnityAdsFailedToLoad(String placementId, UnityAds.UnityAdsLoadError error, String message) {
      Log.e("UnityAdsExample", "Unity Ads failed to load ad for " + placementId + " with error: [" + error + "] " + message);
    }
  };

  private IUnityAdsShowListener showListener = new IUnityAdsShowListener() {
    @Override
    public void onUnityAdsShowFailure(String placementId, UnityAds.UnityAdsShowError error, String message) {
      Log.e("UnityAdsExample", "Unity Ads failed to show ad for " + placementId + " with error: [" + error + "] " + message);
      // Re-enable the button if the user should be allowed to watch another rewarded ad
      rewardedButton.setEnabled(true);
    }

    @Override
    public void onUnityAdsShowStart(String placementId) {
      Log.v("UnityAdsExample", "onUnityAdsShowStart: " + placementId);
    }

    @Override
    public void onUnityAdsShowClick(String placementId) {
      Log.v("UnityAdsExample", "onUnityAdsShowClick: " + placementId);
    }

    @Override
    public void onUnityAdsShowComplete(String placementId, UnityAds.UnityAdsShowCompletionState state) {
      Log.v("UnityAdsExample", "onUnityAdsShowComplete: " + placementId);
      if (state.equals(UnityAds.UnityAdsShowCompletionState.COMPLETED)) {
        // Reward the user for watching the ad to completion
      } else {
        // Do not reward the user for skipping the ad
      }
      // Re-enable the button if the user should be allowed to watch another rewarded ad
      rewardedButton.setEnabled(true);
    }
  };

  @Override
  protected void onCreate (Bundle savedInstanceState) {
    super.onCreate (savedInstanceState);
    setContentView (R.layout.activity_main);

    // Initialize the SDK:
    UnityAds.initialize(getApplicationContext(), unityGameID, testMode, this);

    // Find the button in the view hierarchy and set its click function to load ads:
    rewardedButton = findViewById (R.id.showAdButton);
    rewardedButton.setOnClickListener (new View.OnClickListener () {
      @Override
      public void onClick (View v) {
        DisplayRewardedAd ();
        rewardedButton.setEnabled(false);
      }
    });
  }

  @Override
  public void onInitializationComplete() {
    rewardedButton.setEnabled(true);
  }

  @Override
  public void onInitializationFailed(UnityAds.UnityAdsInitializationError error, String message) {
    Log.e("UnityAdsExample", "Unity Ads initialization failed with error: [" + error + "] " + message);
  }

  // Implement a function to load an rewarded ad. The ad will start to show after the ad has been loaded.
  public void DisplayRewardedAd () {
    UnityAds.load(adUnitId, loadListener);
  }
}
