修订：升级到AS(3.2.1(和Gradle(4.6(后出现新错误。
这是build.gradle代码。Gradle属性具有"android.enableAapt2=true"并且包装器属性具有"distributionUrl=https://services.gradle.org/distributions/gradle-4.6-all.zip">

尝试了许多解决方案，包括无效缓存/重新启动、关闭和导入项目、删除缓存文件、重新安装Android Studio、Clean&重建他们中没有一个人能够成功地完成这个项目。
还有其他可能的解决方案吗？
尝试删除gradle缓存。例如，在Windows:上
C:Users[username].gradlecaches
然后执行以下操作：
Android Studio>File>Sync with File SystemAndroid Studio>File>Sync Project with Gradle FilesAndroid Studio>Build> Clean ProjectAndroid Studio>Build> Rebuild Project
在这种找不到错误源的情况下，请尝试创建一个新项目，然后首先，只将.java文件复制到新项目中，然后，尝试复制layout和drawable文件夹。然后尝试在build.gradle文件中逐个添加dependencies，每次添加后同步，看看是哪一个导致了问题。
此外，我应该在你的build.gradle:中提到一些建议
首先将这一行移到顶部：
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.android.application'之后
此外，我建议您迁移到Androidx，而不是支持库。
我也不会再使用杰克的黄油刀了。现在Android中有视图绑定。使用：在这里解释
