无法解析Android支持库

Question

更新Android Studio后，Android设计库已解决，但Android支持库未解析。

Gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.abc.testapp"
        minSdkVersion 16
        targetSdkVersion 23
        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:design:23.3.0'
}

我正在使用Android Studio 2.1.2

修改

这很奇怪，因为支持库的v4和v7版本都包含在设计库的依赖项中

\--- com.android.support:design:23.3.0                                                         
     +--- com.android.support:appcompat-v7:23.3.0
     |    +--- com.android.support:support-vector-drawable:23.3.0
     |    |    \--- com.android.support:support-v4:23.3.0
     |    |         \--- com.android.support:support-annotations:23.3.0
     |    +--- com.android.support:animated-vector-drawable:23.3.0
     |    |    \--- com.android.support:support-vector-drawable:23.3.0 (*)
     |    \--- com.android.support:support-v4:23.3.0 (*)
     +--- com.android.support:support-v4:23.3.0 (*)
     \--- com.android.support:recyclerview-v7:23.3.0
          +--- com.android.support:support-v4:23.3.0 (*)
          \--- com.android.support:support-annotations:23.3.0

更新

当我运行命令＆＃39; gradew app：dependencies ＆＃39;为了获得项目依赖性，Android Studio下载了很多＆＃39; .pom＆＃39;显示结果之前的文件。

但在此之后问题得到了解决，并且使用现有的gradle文件构建成功。

是否有人可以了解背景中可能发生的事情？

Answer 1

遵循两个步骤：

<强> 1。首先从SDK管理器更新您的支持库：

<强> 2。在Build gradle中添加以下依赖项：

compile "com.android.support:support-v4:23.2.0"
compile "com.android.support:appcompat-v7:23.2.0"

Answer 2

尝试将SDK管理器上的Android支持库升级到最新版本。
