Android Mopub Native

請建立一個Class並繼承Mopub所提供的CustomEventNative

Class實作內容如下：

 package com.taiwanmobile.pt.adp.mediation;
  
 import android.app.Activity;
 import android.content.Context;
 import android.util.Log;
 import android.view.View;

 import com.taiwanmobile.pt.adp.view.TWMAdViewListener;
 import com.taiwanmobile.pt.adp.view.TWMNativeAd;
 
 import org.json.JSONException;
 import org.json.JSONObject;
 
 import java.util.Map;
 
 // 需將本class的完整類別名稱 com.taiwanmobile.pt.adp.mediation.TAMediaMopubNative 填入後台的Custom Event Class欄位
