找不到'com.android.support:design:22.2.0'。

Question

我想使用FloatingActionButton，但我需要这个库：

compile 'com.android.support:design:22.2.0'

但是当我将它添加到我的Gradle中时，我收到以下信息：

A problem occurred configuring project ':myModule'.
Could not resolve all dependencies for configuration ':myModule:_debugCompile'.
   Could not find com.android.support:design:22.2.0.
     Searched in the following locations:

我尝试更新我的Android SDK，但是所有内容都是最新的：

那么为什么无法解决com.android.support:design:22.2.0？

这是我的gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "de.bla.myProject"
        minSdkVersion 19
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

    buildTypes {
        debug {
            debuggable true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile project(':androidcircularcrop_lib')
    compile 'com.google.code.gson:gson:2.2.4'
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.android.support:design:22.2.0'
    compile files('libs/eventbus-3.0.0-beta1.jar')
    compile files('libs/mpandroidchartlibrary-2-1-0.jar')
    compile files('libs/picasso-2.4.0.jar')
    compile files('libs/YouTubeAndroidPlayerApi.jar')
}

请发布您的模块 build.gradle。 - Blackbelt

尝试将您的 buildToolsVersion 设置为 22.0.1。 - Mikhail

添加了Gradle文件。 - Mulgard

查看您的构建文件，始终将目标和编译SDK设置为相同的数字。Appcompat库也是SDK的一部分，因此使用22.x.x支持库时，您需要至少22个SDK来确保兼容性，更不用说找到库了。 正如Arkadiy建议的那样，建议使用与Android Studio兼容的最新构建工具和Gradle版本。
