Question

尝试通过Refractor迁移到androidx>迁移到AndroidX，我已经尝试了很多次（使缓存无效并重新启动，清理，重建），但是每次完成一些处理和加载并出现以下错误日志时：

*style="background-image: url('');" * /

这些是我的项目级别gradle文件：

这些是我的应用程序级别的gradle文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.3.11'
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
        classpath 'io.fabric.tools:gradle:1.27.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.google.com/' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 1

这是一个已知问题，记录在这里：https://issuetracker.google.com/issues/123303598

一种替代方法是使用和修改此脚本并手动进行转换：https://gist.github.com/dlew/5db1b780896bbc6f542e7c00a11db6a0

Answer 2

尝试在<script> var nameInput = document.getElementById('simple-input1'); document.querySelector('form.form').addEventListener('submit', function(e) { //prevent the normal submission of the form e.preventDefault(); console.log("Username: " + nameInput.value); }); var nameInput1 = document.getElementById('simple-input2'); document.querySelector('form.form').addEventListener('submit', function (e) { //prevent the normal submission of the form e.preventDefault(); console.log("Password: " + nameInput1.value); }); </script>中添加这两行：

gradle.properties

并还将您的库更新为适用于您的用例的最新版本。

Answer 3

因此，此错误已在Android Studio 3.4中修复。尽管您必须手动更改大多数导入和XML文件。

无法迁移到androidX
