Load WebExtensions on GeckoView

Question

I'm working with GeckoView and met problem with installing AddOns. As suggested on Documentation, I've provided XPI compatible with Android, but nothing changes. Copying file to Assets doesn't make a change. Browser doesn't acknowledge WebExtension.

private fun setupGeckoView() {
        geckoSession?.permissionDelegate = object : GeckoSession.PermissionDelegate {
            override fun onContentPermissionRequest(
                session: GeckoSession,
                perm: GeckoSession.PermissionDelegate.ContentPermission
            ): GeckoResult<Int>? {
                return super.onContentPermissionRequest(session, perm)
            }
        }

        geckoView = findViewById(R.id.geckoView)
        val runtime = GeckoRuntime.create(this)

        runtime.settings.consoleOutputEnabled = true
        runtime.webExtensionController.promptDelegate = PromptListener(runtime.webExtensionController)
        runtime.webExtensionController
            .install("https://addons.mozilla.org/android/downloads/file/3719055/youtube_high_definition-85.0.0-an+fx.xpi")

        geckoSession.open(runtime)
        geckoView.setSession(geckoSession)

        geckoSession.loadUri("https://www.youtube.com")
    }

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.gv.webapp">

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.webapp">
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <!--<provider
            android:authorities="com.gv.webapp"
            android:name="com.gv.webapp.Provider">
            <grant-uri-permission android:path="string"
                android:pathPattern="string"
                android:pathPrefix="string" />
        </provider>-->
    </application>

</manifest>

I'm checking logs and the result is confusing. I've got prompt that WebExtension is installed, but when I looking at controller.list() it's empty.

You may be missing a PermissionDelegate:

geckoSession?.permissionDelegate = object : GeckoSession.PermissionDelegate {
    override fun onContentPermissionRequest(
        session: GeckoSession,
        perm: GeckoSession.PermissionDelegate.ContentPermission
    ): GeckoResult<Int>? {
        return super.onContentPermissionRequest(session, perm)
    }
}

Permission delegate allows you to handle requests from Gecko for any permission that needs handling.

Adding ```PermissionDelegate``` helped, but I still didn't get any message on console regarding AddOn. So I've hooked PromptDelegate ```runtime.webExtensionController.promptDelegate = PromptListener()```. Now I know that GeckoView is trying to load WebExtension, but it's still not running for some reason. When I tried to check if everything is OK with ```runtime.webExtensionController.list()``` I got empty list. – KwarcPL Feb 17 '22 at 18:43
Could you update your original question with the manifest? And the JS your are trying to attach? Will take a look – D.H. Feb 17 '22 at 19:55
I've updated my OP. – KwarcPL Feb 19 '22 at 13:51
@KwarcPL oh not the Android manifest - the extension manifest - each JS extension requires a manifest - did make one? Take a look at this page: https://firefox-source-docs.mozilla.org/mobile/android/geckoview/consumer/web-extensions.html – D.H. Feb 20 '22 at 18:04
I'm loading XPI directly from Firefox page. So I believe XPI is all right. – KwarcPL Feb 27 '22 at 11:14
