【问题描述】：

我正在创建一个新的颤振项目：

flutter create --androidx project_name

创建的项目显示AndroidX 支持。仍然在使用很多插件时，包括官方插件。像这个颤动的camera 插件一样，我收到以下错误：

BUILD FAILED in 24s
The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
Building plugin camera...

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'camera'.
> SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 2s

The plugin camera could not be built due to the issue above.

android/app/build.gradle：

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) 
    localPropertiesFile.withReader('UTF-8')  reader ->
        localProperties.load(reader)
    


def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) 
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")


def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) 
    flutterVersionCode = '1'


def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) 
    flutterVersionName = '1.0'

    source '../..'

    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'

build.gradle：

buildscript 
    ext.kotlin_version = '1.3.50'
    repositories 
        google()
        jcenter()
    

    dependencies 
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    


allprojects 
    repositories 
        google()
        jcenter()
    


rootProject.buildDir = '../build'
subprojects 
    project.buildDir = "$rootProject.buildDir/$project.name"

subprojects 
    project.evaluationDependsOn(':app')


task clean(type: Delete) 
    delete rootProject.buildDir

此外，错误不是连续的。有时应用程序运行时没有任何错误，有时它会给出上述错误。并非所有插件都会发生这种情况。一些插件工作正常，但其他插件会出现此错误。尽管所有这些插件都是针对 androidX 的。我正在使用最新版本，颤振医生没有给出任何错误。另外，我在模拟器和真机上都测试过，都报同样的错误。

【问题讨论】：

添加你的 build.gradle

现在，我添加了 build.gradle。

【参考方案1】：

在 android/app/build.gradle 中添加以下行：

multidexEnabled true
