Ionic Fastlane | Android "error: package android.support.v4.content does not exist"-CodePudding

I have an Ionic project I'm working with that is having trouble building to Android. I inherited this project, so that's why I'm not 100% familiar with Fastlane and how it's building the java files. Additionally, I'm on WSL2 and using sdkmanager with the following installed packages:

Installed packages:=====================] 100% Fetch remote repository...

platforms;android-29 | 5       | Android SDK Platform 29        | platforms/android-29

When I run bundle exec fastlane android build it does a whole lot of magic, but in the end, results in the following error:

I've seen some thoughts about newer SDK versions using androidx.core.content.FileProvider instead of android.support.v4.content.FileProvider. Since the entire Android portion is built / generated automatically, I obviously can't change the java file because it will just get overwritten.

Here's a line of the Fastfile that may be helpful:

desc 'Compile a new build for Android'
lane :build do |options|
  Dir.chdir('..') do
    before_build(options)
    ionic_build
    sh("ionic cordova build android --device --release --aot false --environment prod --output-hashing all \
    --sourcemaps false --extract-css true --named-chunks false --build-optimizer true --minifyjs=true \
    --minifycss=true --optimizejs=true")
    deeplinks(action: 'uninstall')
  end
end

CodePudding user response：

cordova-plugin-androidx-adapter will migrate older libraries to use AndroidX Support Libraries automatically. I believe this is needed when you target Android 10 or higher, which is when the switch was made. Once all of your plugins support AndroidX, you can remove the adapter plugin.
