Android Studio AdMob

Question

我已经从Eclipse转换到使用Android Studio，并且一切都可以使用，除了在尝试将AdMob合并到我的项目中时出现问题。我之前的项目已经正确设置了代码，所以只需要告诉Android Studio构建它即可。

我阅读了很多关于将.jar添加到libs文件夹中的问题，但是我认为最新版本的Android Studio更改了布局。因此，我只需将其拖放到.idea > libraries中，然后右键单击并“添加为库”。

在Project Structure中，我有两个模块，在“-”下，显示列出了所有依赖项，包括support-v4-18.0.0和GoogleAdMobAdsSdk-6.4.1，并标记为导出和编译范围。

在Android Studio的预览窗口中，它正确显示了AdView，但在运行时会崩溃。我已经尝试过使用“gradlew clean”和多次重建项目，但都没有成功。

目前，该项目在任何布局上都可以正常工作，除非我在某个页面上使用AdView。如果我确实在页面上使用了它，则会出现“java.lang.ClassNotFoundException：com.google.ads.AdView”的错误，指向我使用一个填充器来填充我的布局的那一行。

调用堆栈：

这句话所指的是：

        v = inflater.inflate(R.layout.display_main, container, false);

build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

apply plugin: 'android'



repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion "18.1.0"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 18
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:18.0.0'
    compile files('libs/GoogleAdMobAdsSdk-6.4.1.jar')
}

感谢任何帮助。

问题已解决，经过一段时间的努力，我终于成功了。

对于任何想要解决这个问题的人，请创建一个新的libs文件夹，并将GoogleAdMobAdsSdk-6.4.1.jar放入其中。并确保你的依赖关系如下：

dependencies {
    compile 'com.android.support:appcompat-v7:18.0.0'
    compile files('libs/GoogleAdMobAdsSdk-6.4.1.jar')
}

虽然我不确定文件夹需要放在哪里，但我只是复制并粘贴了相同的文件夹，然后运行了以下命令：

gradlew clean

希望那样应该能够起作用。
