Question

我是 android studio 的新手，我从 eclipse mars 对我的应用程序进行分级并将其导入到 android studio，但它显示以下错误。我已经遵循了这么多答案但无法成功，谁能告诉我是什么问题，我在这里面临。提前致谢！

   apply plugin: 'com.android.application'


dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':android-support-v7-appcompat')
    compile project(':google-play-services_lib')
    compile project(':FacebookSDK')
}



android {
    compileSdkVersion 21
    buildToolsVersion "22.0.1"




    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

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

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

用途：

apply plugin: 'com.android.application'

而不仅仅是安卓
