Ionic 3 android构建失败，并在IonicWebViewEngine.java和所有照相机Java文件（CameraLauncher.java，FileProvider.java等）上出错。
我尝试添加插件cordova-android-support-gradle-release和cordova-plugin-android-support-v4，但似乎没有任何效果。
请帮助！
如果我查看Android Studio SDK管理器-> SDK工具->支持存储库，我会看到已安装Android支持存储库47.0.0。
离子CLI：5.2.2 科尔多瓦CLI：9.0.0 Android SDK工具：26.1.1

请查看IonicWebViewEngine.java文件
main_root/plugins/cordova-plugin-ionic-webview/src/android/com/ionicframework/cordova/webview/IonicWebViewEngine.java
在第11行中，您将看到此代码
import android.support.annotation.RequiresApi;
请更改为：
import androidx.annotation.RequiresApi;
然后删除/添加Android平台，然后您就可以通过离子CLI命令行构建APK

如果您在 config.xml 中使用 AndroidX = true 将 cordova-plugin-ionic-webview 升级到 5.0.0 也修复了它。
