Import of org.mozilla.geckoview.GeckoRuntime, org.mozilla.geckoview.GeckoSession and org.mozilla.geckoview.GeckoView not working in Android Studio

Question

For creating browser I need Mozilla GeckoView. I did exact the steps of this link, but when I try to import the packages above, theres a compiler error.

import org.mozilla.geckoview.GeckoRuntime;
import org.mozilla.geckoview.GeckoSession;
import org.mozilla.geckoview.GeckoView;

I copied this to the Main activity. Did I do anything wrong, or does anybody know how to fix this?

**settings.gradle **

pluginManagement {
    repositories {
        gradlePluginPortal()
        google()
        mavenCentral()
    }
}
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        maven {
            url "https://maven.mozilla.org/maven2/"
        }
        google()
        mavenCentral()
    }
}
rootProject.name = "SauspielA11GeckoView"
include ':app'

**build.gradle **

    id 'com.android.application'

**MainActivity.java **

package com.chrome.sauspiela11geckoview;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import org.mozilla.geckoview.GeckoRuntime;
import org.mozilla.geckoview.GeckoSession;
import org.mozilla.geckoview.GeckoView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

Answer 1

Change:

ext {
    geckoviewChannel = "nightly"
    geckoviewVersion = "108.0.20221215175817"
}

By:

ext {
    geckoviewChannel = "x86_64" // arm64-v8a or channel desired
    geckoviewVersion = "108.0.20221215175817"
}

Channels and versions: https://maven.mozilla.org/?prefix=maven2/org/mozilla/geckoview/

Answer 2

Into build.gradle just change this line:

implementation "org.mozilla.geckoview:geckoview-${geckoviewChannel}:${geckoviewVersion}"

to

implementation "org.mozilla.geckoview:geckoview:113.0.20230501151611"

NB: geckoview is stable now!

Happy coding :)
