android - 将使用 AndroidX 的自定义 .aar 库添加到 Cordova 插件

Question

客观的

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

系统

操作系统:Ubuntu 18.04.2 LTS

IDE:VSCode 和 Android Studio

电话:Nexus 4 - Android 5.1.1

Cordova 版本:8.1.2 (cordova-lib@8.1.1)

Cordova 应用的 SDK 信息(来自 build.gradle):

defaultBuildToolsVersion="27.0.1" //String
defaultMinSdkVersion=19 //Integer - Minimum requirement is Android 4.4
defaultTargetSdkVersion=27 //Integer - We ALWAYS target the latest by default
defaultCompileSdkVersion=27 //Integer - We ALWAYS compile with the latest by default

我试过的

我已经从该项目中创建了一个 .aar 文件，并且正在尝试将其添加到我的 Cordova 插件中。我可以从该项目中导入方法，但是一旦我打开使用这些方法的 Activity (应用程序仍然正确构建)，应用程序就会崩溃。

03-21 12:35:59.728 12235-12235/io.cordova.hellocordova E/AndroidRuntime: FATAL EXCEPTION: main
Process: io.cordova.hellocordova, PID: 12235
java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/core/content/ContextCompat;

我想这可能是因为 androidx感谢 Failed resolution of: Landroidx/core/content/ContextCompat; .所以我将该行添加到我的plugin.xml文件:

<!-- I have the same version of androidx.appcompat in my aar library -->
<framework src="androidx.appcompat:appcompat:1.0.0-beta01"/>

通过该更改，应用程序拒绝构建并且我得到了这些错误(我用 <projectpath> 替换了绝对项目路径):

有了这些错误，我开始认为这可能是 cordova 之间的错误。和 androidx图书馆。要检查我是否尝试使用该行添加不同的库( Volley ，我的 aar 库不需要它):

<framework src="com.android.volley:volley:1.1.1"/>

应用程序构建成功。但是当我运行它时，一旦我们开始使用 AAR 库中的元素，它就会崩溃。 (参见步骤 1)

Cordova 与 androidx 兼容吗？如果是，是什么阻止我使用它？

看起来它与我得到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。所以我无法确认。

PS:我试图尽可能详尽，请询问您是否缺少信息。

编辑#1:

我试图改变androidx返回 appcompat在我的 .aar 库中。我生成了一个新的 .aar 并使用了

<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

我记得在 Cordova 的官方文档中，他们使用了 appcompat 的导入:Cordova - Plugin.xml - Framework .所以我用了这个:

<!-- Depend on v21 of appcompat-v7 support library -->
<framework src="com.android.support:appcompat-v7:21+" />

它构建正确。但仍然会崩溃，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，因为我还有其他依赖它的模块。

Answer 1

缺少的资源(ttcIndex 等)仅在 API 28 中添加 - 这就是它们位于名为 values-v28 的文件夹中的原因。 .

您需要更新您的 compileSdkVersion到 28 才能成功编译。
