java - Android Studio找不到资源且资源链接失败

Question

最近我在使用 AAPT2 时遇到了问题。该问题是由我的用户名包含非 ASCII 字符引起的。我创建了另一个 Windows 帐户(没有非 ASCII 字符)并在其上安装了 Android Studio。然后我打开了我的旧项目，当 AS 要求我更新时我同意了。现在，当我尝试构建我的应用程序时，我收到以下错误:

Android resource linking failed D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:7: error: resource android:attr/dialogCornerRadius not found. D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-v28\values-v28.xml:11: error: resource android:attr/dialogCornerRadius not found. D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2970: error: resource android:attr/fontVariationSettings not found. D:\Android_Studio\Praca\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:2971: error: resource android:attr/ttcIndex not found. error: failed linking references.

我在 StackOverflow 发现的大多数帖子都表明这个问题可能与支持库有关，他们说版本可能是错误的。我怎样才能更改版本？我的项目也使用 OpenCV 库，它的配置可能无效。 我已经尝试过清理和重建项目并在 Gradle 中调整compileSDKVersion。

这是values-v28.xml文件

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Base.Theme.AppCompat" parent="Base.V28.Theme.AppCompat"/>
<style name="Base.Theme.AppCompat.Light" parent="Base.V28.Theme.AppCompat.Light"/>
<style name="Base.V28.Theme.AppCompat" parent="Base.V26.Theme.AppCompat">
    <!-- We can use the platform styles on API 28+ -->
    <item name="dialogCornerRadius">?android:attr/dialogCornerRadius</item>
</style>
<style name="Base.V28.Theme.AppCompat.Light" parent="Base.V26.Theme.AppCompat.Light">
    <!-- We can use the platform styles on API 28+ -->
    <item name="dialogCornerRadius">?android:attr/dialogCornerRadius</item>
</style>

这是 list :

下面是我的 build.gradle 文件应用程序模块。在此文件中，带有支持库的子条款“依赖项”条目带有下划线，AS 向我显示警告:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:customtabs:26.1.0

我尝试将版本更改为较新或较旧的版本，但此警告仍然出现。

我通过将compilesdkversion更新为28修复了同样的错误，因为目前我的构建工具版本是28.0.3，因此版本应该与完美构建相同。 另请检查您的实现“com.android.support:appcompat-v7:28.0.0” 将各自的依赖版本更改为28，这样可以防止运行时崩溃
