这是我的 build.gradle 文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "au.com...."
        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 'org.apache.httpcomponents:httpclient:4.5'
    compile 'com.loopj.android:android-async-http:1.4.9'

请提供需要翻译的英文内容。对于Java和XML代码，请提供更具体的说明，以便我能够理解您的需求并为您提供更准确的答复。 - Vivek Mishra

缺少Design Support库，您应该在build.gradle中添加compile 'com.android.support:design:23.2.1'。 - anhtuannd

Answer 1

将compile 'com.android.support:design:23.2.1'添加到build.gradle中以解决问题。

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar'])
   testCompile 'junit:junit:4.12'
   compile 'org.apache.httpcomponents:httpclient:4.5'
   compile 'com.loopj.android:android-async-http:1.4.9'
   compile 'com.android.support:appcompat-v7:23.2.1'
   compile 'com.android.support:design:23.2.1'
}

记得将 23.2.1 更改为您正在使用的版本号

如何找到 AndroidX 的依赖关系 - Kifayat Ullah

Answer 2

经过一番搜索，我发现了jetifier。

npm install jetifier
npx jetify
npx cap sync android

使用Jetifier来修补未更新为AndroidX的插件
