我是
Android的新手,我安装了Android Studio 1.4.1,我收到了以下错误.我可以解决这些错误吗？

的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.admin.myfirstapp"
        minSdkVersion 15
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:20.+'
}

最佳答案 你在防火墙后面吗？您可能需要在项目build.gradle中执行此操作：

repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
}
