我使用的是全新的Andr​​oid工作室。我已经做了一个应用程序，并能正常工作，现在我已经加入AdMob的SDK。所以我把库文件夹中的罐子，然后右键单击添加为库。 我对我的智能手机上运行该项目，但该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？我认为这将是一些错误的AdMob SDK的进口。

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

感谢您！

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

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

    <activity
            android:name="com.google.ads.AdActivity"
               android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />

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

</application>

这是布局的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>

这是logcat的

如果我隐藏了AdMob的code在布局XML的应用程序正常工作

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

谢谢！

推荐答案

这是一个有点棘手，但这里是解决方案：

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

目前的preVIEW版本不编辑build.gradle文件，即使你已经添加了AdMob的库在菜单的依赖关系。 你可以做的是手动添加的依赖，这是非常容易的：

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:

双击左侧导航菜单中的文件build.gradle。 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（库/ GoogleAdMobAdsSdk-6.4.1.jar'）

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

这应该是这样的：

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
    }
}
