After Capacitor 6 upgrade, all plugins are "not implemented on android"

Bug Report

I upgraded to Capacitor 6 yesterday, then spent half a day trying to fix "plugin is not implemented on android" errors.

Plugin(s)

I think it affects every plugin, but confirmed the error occurs with:

"@capacitor/clipboard": "^6.0.0",
"@capacitor/geolocation": "^6.0.0",
"@capacitor/share": "^6.0.0",
"@capacitor/splash-screen": "^6.0.0",
"@codetrix-studio/capacitor-google-auth": "^3.4.0-rc.1",

[success] Android looking great! 👌

Platform(s)

Android 14

Current Behavior

Using any plugin triggers "[plugin name] plugin is not implemented on android"

Expected Behavior

No errors like in Capacitor 5

Other Technical Details

Additional Context

Tried:

• npx cap migrate
• npx cap sync android
• Deleted android folder, then npx cap add android
• Deleted node_modules, then yarn
• Restarted Android Studio, clean project, reload from disk, rebuild, etc
• Created a whole new project, npx cap init, npx cap add android, etc. Still doesn't work

If I use my old Android build with Capacitor 5 plugins, but load a webview containing the JS for Capacitor 6 plugins, every plugin still works. Plugins all work on iOS.

Is there already a solution for how to fix this? I have Android 14, and after updating the app to Capacitor 6, none of the plugins are visible. The app was built using redirect.

I found the solution, and it's quite simple. I just needed to set the url in the configuration of capacitor.config.json.

"server": {
    "url": "https://youdomain.com",
    "allowNavigation": ["youdomain.com"]
},

Since Android 14 supports WebViewFeature.isFeatureSupported(WebViewFeature.DOCUMENT_START_SCRIPT), by default, if you don't specify a url in the configuration, the appUrl is set to localhost, which causes the injector to behave incorrectly."
