Question

我在此链接中了解了Admobs的Adbanner https://developers.google.com/admob/android/quick-start但是当我在设备和模拟器中测试我的应用时，我的应用中没有Adbanner节目

我在Stacktrace中遇到以下错误

据我所知，使用IDE（eclipse）会出现这个问题，所以我在我的设备上测试游戏，但横幅没有出现在布局的底部

红色背景是图片，黄色背景是adbanner必须出现的adbanner地方但不是

我已将此以下代码放入我的课程中，如上面链接中的google admobs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);

抱歉，我没有把我的所有代码都放在一边，因为它很多，而且我的项目中没有使用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>

U P D A T E D

我在logcat中遇到这个错误是什么意思？

09-24 22:51:33.318: E/dalvikvm(24493): Could not find class 'com.google.android.gms.common.h.c', referenced from method com.google.android.gms.common.app.GmsApplication.onCreate

我是否遗漏了使横幅无法显示的内容？

任何人都可以帮我解决这个问题，以便横幅出现吗？感谢提前

Answer 1

对于测试，您应使用以下单位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insterstitial广告，它是ca-app-pub-3940256099942544/1033173712。

另外，请确保您已从SDK Manager更新了Android支持库，并在app / build.gradle中包含了Play服务依赖项

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以了解安装Play服务库的步骤。

或者，您可以参考the commit history of one of my Git repo来解除横幅广告和插页式广告的实施。

Answer 2

如果你没有Android工作室，只需从android sdk manager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，你会在你的项目中找到一个包含该jar的jar然后尝试运行它。希望它会帮助你

Answer 3

但这并不需要太多赏金。

首先，复制google play服务项目中的.jar文件 - ＆gt; libs文件夹，并将其粘贴到项目libs文件夹中。

右键单击它并转到构建路径 - ＆gt;添加到构建路径

我也猜测你导出了你的申请吗？好吧有这个名为Proguard谷歌他的淫秽工具 - （他导致你的代码有很多变化）

在项目中查找名为proguard-project.txt的文件，将其打开并添加

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

Answer 4

由于模拟器上未安装Google Play服务，因此无法在模拟器上测试admob。因此，您必须在Real Device上进行测试，或使用Jenny Motion Emulator并在那里安装Google Play服务。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"    />

广告横幅未显示
