无法导入 facebook-sdk 4.0.1

我有 android studio 1.1.0，我刚刚创建了一个新项目，我正在尝试导入新的 facebook-sdk 4.0.1 但无法执行此操作，我遵循脸书入门

But can not get it work. My app structure

我的 build.gradle(Project: MyApplication) 文件是：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        //mavenCentral()
    }
}

我的 build.gradle(Module: app) 文件是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.hema.myapplication"
        minSdkVersion 9
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.facebook.android:facebook-android-sdk:4.0.1'
}

最后错误信息是：

Error:(28, 13) Failed to resolve: com.facebook.android:facebook-android-sdk:4.0.1
<a href="openFile">Show in File</a><br><a href="open.dependency.in.project.structure">Show in Project Structure dialog</a>

Edit我在 build.gradle(Project: MyApplication) 文件的存储库闭包中添加了 mavenCentral() ，但无法处理相同的错误消息。

I solved the problem, It was in my Gradle settings >> Unchecked Offline work
