据我所知，使用 IDE (eclipse) 会发生这个问题，所以我在我的设备上测试了游戏，但横幅没有显示在布局的底部

红色背景是图片，黄色背景是广告横幅必须出现的地方，但它没有

我已将以下代码放入我的班级，如上面链接中的 google admobs 中所述

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

public class bplay extends Activity implements View.OnClickListener{

    private AdView mBanner;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.bplay);

        mBanner  = (AdView) findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();
        mBanner.loadAd(adRequest);

对不起，我没有把我所有的代码都放进去，因为它太多了，我没有在我的项目中使用 app compat

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="16" />

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />    

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar">
    <meta-data android:name="com.google.android.gms.version"
               android:value="@integer/google_play_services_version" />
    <activity
        android:name=".Ablankscreen"
        android:screenOrientation="portrait">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
        android:theme="@android:style/Theme.Translucent" />

在我的 xml 布局中，我使用的是线性布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="3dp"
    android:background="@drawable/backgroundblankyellow"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/rulesimage"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:scaleType="fitXY"
        android:src="@drawable/playimage"
        android:visibility="visible" />

     <com.google.android.gms.ads.AdView
         android:id="@+id/adView"
         android:layout_width="fill_parent"
         android:layout_height="wrap_content"
         ads:adSize="BANNER"
         ads:adUnitId="@string/banner_ad_unit_id" >

    </com.google.android.gms.ads.AdView>    

</LinearLayout>

我在 logcat 中收到此错误是什么意思？

我是否遗漏了一些使横幅不显示的内容？

谁能帮我解决这个问题，以便显示横幅？提前致谢

【问题讨论】：

你在什么时候得到这个异常？

标签： java android eclipse admob banner

【解决方案1】：

不过，这并不需要太多的赏金。

首先，将 .jar 文件复制到你的 google play services 项目 -> libs 文件夹中，并粘贴到你的项目 libs 文件夹中。

右键单击它并转到构建路径 -> 添加到构建路径

我猜你也导出了你的应用程序吧？好吧，有一个名为 Proguard google him 的混淆工具-（他导致对您的代码进行了很多更改）

在您的项目中查找名为 proguard-project.txt 的文件，打开并添加

-keep class com.google.android.gms.ads.**

【讨论】：

我已经做了所有这些，但横幅也没有出现
先生，您介意压缩您的项目吗？并在您的问题中添加指向它的链接，以便我可以下载并查看？@Archanister
也许稍后，但我有个问题忘了问 Eltz
我之前忘记使用 testdevice 来在我的项目中获取测试广告，所以我只是将没有 addTestDevice 的 adview 代码放在那里，但我的插页式广告在没有 addTestDevice 之前工作正常，所以 addTestDevice 这导致横幅广告不会不出现？使用 addTestDevice 很重要吗？
嗯，我不这么认为，您是否重新检查了您的添加 ID？@Archanister addTestDevice 告诉 admob 在特定设备上为您提供测试添加。我，但你已经解决了吗？

【解决方案2】：

对于测试，您应该使用以下单元 ID。将其粘贴到您的 values/strings.xml 中

对于横幅广告：

<string name="banner_ad_unit_id">ca-app-pub-3940256099942544/6300978111</string>

对于插页式广告，它是 ca-app-pub-3940256099942544/1033173712 。

还要确保您已从 SDK 管理器更新了 Android 支持库，并将 Play Services 依赖项包含在 app/build.gradle 中

dependencies {
    ...
    compile 'com.google.android.gms:play-services-ads:7.8.0'
}

Eclipse 用户，请查看the Eclipse with ADT tab on the official Google Dev documentation，了解安装 Play 服务库的步骤。

您可以选择参考the commit history of one of my Git repo，它演示了横幅广告和插页式广告的实现。

【讨论】：

但我使用的是 Eclipse，所以那里没有 gradle，横幅广告是否必须需要 Gradle 系统才能显示在游戏或应用程序上？
好吧，我不熟悉 Eclipse 构建系统，但我确信有一种方法可以在 Eclipse 中添加依赖项（或者他们所说的任何东西）。
检查编辑的答案。我已经链接了在 Eclipse 中安装 Play Services 库的说明。

【解决方案3】：

如果您没有 android studios，只需从 android sdk 管理器安装 google play service pakage，然后转到 C:\Users\your_computer_name\AppData\Local\Android\sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs 此处您会在您的项目中找到一个包含该 jar 的 jar，然后尝试运行它。希望对你有帮助

【讨论】：

AppData 文件夹通常是隐藏的，所以请先取消隐藏文件夹

【解决方案4】：

根据您的堆栈跟踪：

   at com.android.ide.eclipse.adt.internal.editors.layout.ProjectCallback.instantiateClass(ProjectCallback.java:442)
    at com.android.ide.eclipse.adt.internal.editors.layout.ProjectCallback.loadView(ProjectCallback.java:194)

您正尝试在 IDE 中执行此操作。这永远不会奏效。部署到设备。

【讨论】：

【解决方案5】：

无法在模拟器上测试 admob，因为模拟器上没有安装 Google Play 服务。所以你必须在真机上测试它或使用 Jenny Motion Emulator 并在那里安装 Google Play Services。这里是工作代码的例子也看看。

<com.google.android.gms.ads.AdView

    android:id="@+id/adView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    ads:adSize="SMART_BANNER"
    android:layout_alignParentBottom="true"
    ads:adUnitId="Your Key "
    android:visibility="visible"    />
