Android Studio - 膨胀类 com.google.ads.AdView 时出错

Android Studio - Error inflating class com.google.ads.AdView(Android Studio - 膨胀类 com.google.ads.AdView 时出错)

问题描述

我正在使用新的 Android Studio.我已经完成了一个应用程序并且工作正常，现在我必须添加 AdMob sdk.所以我把jar放在'libs'文件夹中，然后右键单击添加为库".我在智能手机上运行该项目，但应用程序在启动时崩溃.

I'm using new Android Studio. I've done an application and works fine, now I've to add AdMob sdk. so I put the jar in 'libs' folder and right-click "add as library". I run the project on my smartphone but the application crashes on startup.

我该如何解决这个问题?我认为这将是 AdMob sdk 的导入有问题.

How can i solve this? I think it'll be something wrong with the import of AdMob sdk.

谢谢！

这是xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.my.application"
android:installLocation="preferExternal"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="16" />

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

<application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        //MY ACTIVITY

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity

    <meta-data android:name="ADMOB_PUBLISHER_ID" android:value="a151964f48b17a7"/>

</application>

这是布局xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"

            xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
            tools:context=".MainActivity">

<com.google.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        ads:adSize="BANNER"
        ads:adUnitId="MY_UNIT_ID"
        ads:loadAdOnCreate="true" >
</com.google.ads.AdView>

如果我在布局 xml 中隐藏 AdMob 代码，应用程序可以正常工作

If i hide the AdMob code in layout xml, the application works properly

谢谢！

推荐答案

这有点棘手，但这里是解决方案:

it's a bit tricky but here is the solution:

当前预览版不会编辑 build.gradle 文件，即使您已将 admob 库添加到菜单中的依赖项.你可以做的是手动添加依赖，很简单:

The current preview release doesn't edit the build.gradle file, even if you have added the admob library to the dependencies in the menu. What you can do is to add the dependency manually, it's very easy:

双击导航菜单左侧的build.gradle"文件.添加以下行:

double click on the file "build.gradle" on the left in the navigation menu. Add the following line:

编译文件('libs/GoogleAdMobAdsSdk-6.4.1.jar')

compile files('libs/GoogleAdMobAdsSdk-6.4.1.jar')

应该是这样的:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'

    }
}
apply plugin: 'android'

dependencies {
    compile files('libs/android-support-v4.jar')
    compile files('libs/GoogleAdMobAdsSdk-6.4.1.jar')
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}
