运行“；cordova构建android”；-AAPT:错误：未找到资源android:attr/fontVariationSettings\n android:attr/ttcIndex未找到

我可以在三月份使用command

ionic cordova build android

将我的项目构建到apk文件中，但在四个月左右什么都不做之后，它现在就无法构建了

我已经研究并遵循了一些，但没有任何有效的方法，包括：

$IONAL-v 5.0.3

$cordova-v 9.0.0（科尔多瓦）-lib@9.0.1)

使用依赖项和插件： “@ionic native/brightness”：“^4.15.0”， “@ionic native/core”：“^4.12.2”， “@ionic native/firebase”：“^4.12.0”， “@ionic native/google地图”：“^4.12.0”， “@ionic native/应用程序内浏览器”：“^4.12.0”， “@ionic native/splash screen”：“~4.11.0”， “@ionic native/状态栏”：“~4.11.0”， “@ionic/storage”：“2.1.3”

尝试转到platform/android文件夹，编辑project.properties文件，并将com.android.support:support-v4:+替换为com.android.support:support-v4:27.1.0

---

这只是对该问题的一个快速修复，您必须找到您使用的库来抛出此错误。

将

编译器dkversion

更改为：

compileSdkVersion 28

---

并被添加到api第28级中

我按照这些指南解决了我的问题。谢谢大家的支持。

这样做之后，我构建的应用程序会在28以下的android api版本上运行吗？@BaoNguyen是的，compileSdkVersion和minSdkVersion是不同的。请阅读以下内容：
