我需要为Cordova开发一个插件，它实现了我已经开发的一些代码（aar文件），用于Android应用程序。

cordova和androidx库之间可能存在错误。要检查我是否尝试使用该行添加一个不同的库（使用我的aar库不需要的齐射）：<framework src="com.android.volley:volley:1.1.1"/>
Cordova与androidx兼容吗？如果是，是什么阻止我使用它？
它看起来与我所获得的测试和错误不兼容，但我没有在Cordova文档网站或谷歌搜索中找到有关该主题的相关信息。所以我无法证实。
PS：我尽量详尽无遗，请询问您是否遗漏了相关信息。
androidx更改回appcompat。我生成了一个新的.aar＆used<framework src="com.android.support:appcompat-v7:28.0.0"/>
而不是androidx导入。
结果：与（1.）问题相同。
结论：可能不是因为androidx
<!-- Depend on v21 of appcompat-v7 support library -->
<framework src="com.android.support:appcompat-v7:21+" />
它构建正确。但仍然崩溃，因为.aar文件中使用的函数对于此版本的库不存在。
Process: io.cordova.hellocordova, PID: 16523
java.lang.NoSuchMethodError: No static method checkSelfPermission(Landroid/content/Context;Ljava/lang/String;)I in class Landroid/support/v4/content/ContextCompat; or its super classes (declaration of 'android.support.v4.content.ContextCompat' appears in /data/app/io.cordova.hellocordova-2/base.apk)
如果可能的话，我想继续使用androidx而不是appcompat，因为我有其他依赖它的模块。
缺少的资源（ttcIndex等）仅在API 28中添加 - 这就是为什么它们位于名为values-v28的文件夹中。
您需要将compileSdkVersion更新为28才能成功编译。
感谢此文档Flutter Doc我迁移了我的项目以与Androidx兼容。 （就像Android Studio使用Refactor > Migrate to AndroidX选项一样）是的，它来自Flutter而不是Cordova，但由于它是任何Android项目的一般信息，它仍然适合。
我做的主要事情是：
gradle.properties添加到platforms/androidandroid.enableJetifier=true
android.useAndroidX=true
15升级到1927编译为283.0.0的gradle更新为3.3.2由于我使用Cordova CLI创建了我的项目，我认为它不会像关于这些功能的普通Android项目那样工作，所以我忽略了它。
我已经运行了一些测试，现在应用程序似乎正常。
我不得不再次解决这个问题，所以我之前完成了解决问题的步骤。似乎解决这个问题的是将platform/android/project.properties文件中的版本从target=android-27更改为target=android-28
