Java 更新到Androidx，我可以'；t在发布中生成APK:AAPT2进程意外退出

渐变版本：5.6.2

Android插件版本：3.5.0

编译SDK版本：28

构建工具版本：28.0.3

SDK工具版本：

我有一个Android插件版本3.2.1和Gradle版本4.6的功能版本应用程序，但为了应用新功能，我们必须迁移到androidx

在执行迁移和更新依赖项之后，工作正常，我们在emulator上运行，并在调试构建时测试phone

尽管我们尝试生成发布APK/捆绑包时，由于AAPT2链接中的错误而失败。（AAPT2 AAPT2-3.5.0-5435860-windows守护程序#0:链接期间出现意外错误，试图停止守护程序。 这在正常情况下不应发生，如果发生，请提交问题。）

禁用minifyEnabled选项时会生成APK

但是，我们不能在没有缩小的情况下分发APK

我们一直在尝试以下几点：

1-按照（）建议对Android Gradle插件3.4.0和Gradle版本5.4.1执行降级，但错误仍然存在

2-我使用AAPT2页（）上的命令执行AAPT2命令编译应用程序res文件夹中的媒体，以检查编译应用程序资源时是否出现问题，但编译成功

3-在aaptOptions中使用cruncherEnabled=false和useNewCruncher=false选项

4-在gradle.properties中使用android.enableapt2=false选项，但它已经被弃用

5-在我的gradle控制台中运行assembleDebug和assembleRelease

有时Android studio不会直接检测xml文件中的问题

您可以尝试从Gradle>应用程序>应用程序>生成运行生成任务

这将在控制台的“运行”选项卡下显示错误和警告

---

我创建了一个新项目来进行逐层测试

首先，我们添加了相同的依赖项，并验证了问题不是由与gradle的不兼容引起的

然后我们开始一个接一个地添加RES文件夹，在此过程中，我们能够确定导致此错误的原因是应用程序中的一个布局

最后，为了找出哪些文件是导致错误的原因，我们将布局添加到每个包中，这导致发现我们的8个文件中有一个自定义标记是导致错误的原因。

---

删除此标记修复了我们的问题，由于时间限制，我们没有深入研究此标记中的问题。

我尝试了此执行，但仅返回运行调试时已显示的错误：>AAPT2 AAPT2-3.5.0-5435860-windows守护进程#0:链接期间出现意外错误，试图停止守护进程。这在正常情况下不应发生，如果发生，请提交问题。
