在Android studio中启动AdMob

根据一个教程进行Android studio的导入

下载了jar，然后放到我的lib文件夹中，然后将这行代码添加到build.gradle：

    compile files('libs/android-support-v4.jar', 'libs/GoogleAdMobAdsSdk-6.4.1.jar')

 build.gradle文件如下：

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
        compile files('libs/android-support-v4.jar', 'libs/GoogleAdMobAdsSdk-6.4.1.jar')
    }
}
apply plugin: 'android'

dependencies {
}

android {
    compileSdkVersion 17
    buildToolsVersion "17"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 17
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

然后在build->rebuild工程中报错：

Gradle: A problem occurred evaluating root project 'freeBP'.
> No signature of method: org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.compile() is applicable for argument types: (org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection) values: [file collection]
  Possible solutions: module(java.lang.Object)

我也是遇到这个问题一点头绪都没有 请问你是怎么决绝的
