Support for React Native 0.73 - Android

[casperolesen]

I'm trying to use this library with the latest React Native version 0.73.4

But I'm having problems on Android. I'm running the app from an emulator.

How to reproduce

npx react-native@latest init Readium073 yarn add react-native-readium yarn android

or use my repo

https://github.com/casperolesen/Readium073

Java version error

`Execution failed for task ':react-native-readium:compileDebugKotlin'.

'compileDebugJavaWithJavac' task (current target is 17) and 'compileDebugKotlin' task (current target is 1.8) jvm target compatibility should be set to the same Java version. Consider using JVM toolchain: https://kotl.in/gradle/jvm/toolchain`

I've tried to remove this from the build.gradle

kotlinOptions {
    jvmTarget = "1.8"
  }

This fixes the issues with the Java version.

Build failed with an exception

I'm now getting multiple errors when trying to build like

/react-native-readium/android/src/main/java/com/reactnativereadium/ReadiumView.kt:62:7 'when' expression must be exhaustive, add necessary 'is Failure', 'OpenDrmManagementRequested', 'OpenOutlineRequested', 'StartNewSearch' branches or 'else' branch instead /react-native-readium/android/src/main/java/com/reactnativereadium/epub/UserSettings.kt:226:73 Unresolved reference: webView /react-native-readium/android/src/main/java/com/reactnativereadium/reader/EpubReaderFragment.kt:112:55 Unresolved reference: epub_navigator_tag

I can get the build to complete by fixing or removing the lines with errors.

Metro error

Unable to load script. Make sure you're either running Metro (run 'npx react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release

This is were I'm stuck now.

When I remove react-native-readium the app is running fine again.

I'm not an experienced kotlin developer, but I would like to help fixing this! 🦸‍♂️ I just don't know if it's a small bug or something that needs a bigger rewrite of this library.

If someone else can confirm that it's not working with the latest release of React Native - how should we fix it?
