Android Studio - 扩展类 com.google.ads.AdView 时出错

Question

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。所以我将 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。

我该如何解决这个问题？我觉得导入AdMob sdk会出问题。

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
    </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>

这是日志

如果我在布局 xml 中隐藏 AdMob 代码，应用程序将正常运行

谢谢!

Answer 1

这有点棘手，但这是解决方案:

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。您可以做的是手动添加依赖项，这非常简单:

双击导航菜单左侧的文件“build.gradle”。添加以下行:

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

它应该是这样的:

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
    }
}
