如何在较旧的Android设备上支持Material Design

我正在尝试在我的项目中使用Material Design，但我没有找到导入它的方法 . 我花了很多时间在互联网和stackoverflow尝试用户的建议，但无论我尝试过什么都没有用 .

我在Mac OSX 10.10上使用Android Studio 0.8.14 . 使用gradle 13.2和JDK jdk1.8.0_25.jdk . 从图像中可以看出我的android SDK是完全最新的

这是我的傻瓜

android {
    signingConfigs {
        TESTING {
            keyAlias '****'
            keyPassword '***'
        }
    }
    compileSdkVersion 21
    buildToolsVersion "21.0.2"
    defaultConfig {
        applicationId "********"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName '1.0'
    }
    buildTypes {
        debug {
            applicationIdSuffix '.dev'
        }
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.TESTING
        }
    }
    productFlavors {
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

dependencies {
    compile 'com.android.support:support-v4:21.+'
    compile 'com.android.support:support-v13:21.+'
    compile 'com.android.support:appcompat-v7:21.+'
    compile 'com.android.support:cardview-v7:21.+'
    compile 'com.android.support:recyclerview-v7:21.+'
    compile 'com.google.android.gms:play-services:6.1.+'
    compile fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
}

值/ style.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="AppTheme.Base"/>

    <style name="AppTheme.Base" parent="Theme.AppCompat.Light">
    </style>

</resources>

值-21 / style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme" parent="android:Theme.Material.Light">
        <!-- Customize your theme using Material Design here. -->
    </style>
</resources>

当我在清理gradle之后自动在gradle中添加appcompat时，我的类中的所有R.都不起作用并显示错误消息“无法解析符号R” . 不仅如此，我还收到以下错误和警告：

任何人都可以帮我？难道我做错了什么？

谢谢
