我正在借助this教程制作一个简单的应用，但无法添加广告。
没有它们，游戏运行正常，但出现了Chromium WebView不存在错误和广告出现UnsupportedOperationException错误（我不确定一个错误是否引起另一个错误）。
这是我的SampleGame类（在应用程序启动时调用的类）
package com.harryhochwarter.frugalfarminggame;
import android.os.Bundle;
import com.google.android.gms.ads.*;
import com.kilobolt.framework.Screen;
import com.kilobolt.framework.implementation.AndroidGame;
public class SampleGame extends AndroidGame
{
public static String map;
boolean firstTimeCreate = true;
//
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AdView adView = (AdView)findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
.addTestDevice("AC98C820A50B4AD8A2106EDE96FB87D4")
.build();
adView.loadAd(adRequest);
}
@Override
public Screen getInitScreen()
{
if(firstTimeCreate)
{
Assets.load(this);
firstTimeCreate = false;
}
return new SplashLoadingScreen(this);
}
@Override
public void onBackPressed()
{
getCurrentScreen().backButton();
}
@Override
public void onResume()
{
super.onResume();
//Assets.theme.play();
}
@Override
public void onPause()
{
super.onPause();
//Assets.theme.pause();
}
}
这是我修改的SampleGame的父类

如果需要添加其他代码或信息，请告诉我！
最佳答案
您在这里遇到几个问题：
日志显示您的Google Play服务版本已过时
如您的日志所述，您需要“将AdActivity的主题设置为@android：style / Theme.Translucent以启用透明的背景非页内广告。”
您正在两次调用Activity的#setContentView。一次在活动中，一次在父活动中。这会引起你的悲伤。
关于java - Chromium WebView不存在(UnsupportedOperationException)，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/25468903/
