GeckoView is Firefox Quantum's engine, packaged as a reusable Android library.

Mozilla uses GeckoView to power Firefox Reality, Firefox Focus, and more.

GeckoView serves a similar purpose to Android's built-in WebView, but it has its own APIs and is not a drop in replacement.

Get Started

Building a browser? Check out Android Components, our collection of ready-to-use supporting libraries!

Configure Gradle

You need to add or edit four stanzas inside your module's build.gradle file.

1. Set the GeckoView version

Like Firefox, GeckoView has three release channels: Stable, Beta, and Nightly. Browse the Maven Repository to see currently available builds. 

ext {
    geckoviewChannel = "nightly"
    geckoviewVersion = "64.0.20180927100037"
}

2. Add Mozilla's Maven repository 

repositories {
    maven {
        url "https://maven.mozilla.org/maven2/"
    }
}

3. Configure build flavors

Note: Until we resolve Bug 1485045, you must configure a separate build variant for each CPU architecture. 

android {
    // ...

    flavorDimensions "abi"

    productFlavors {
        x86     { dimension "abi" }
        x86_64  { dimension "abi" }
        arm     { dimension "abi" }
        aarch64 { dimension "abi" }
    }
}

4. Add GeckoView Implementations 

dependencies {
    // ...

    x86Implementation     "org.mozilla.geckoview:geckoview-${geckoviewChannel}-x86:${geckoviewVersion}"
    x86_64Implementation  "org.mozilla.geckoview:geckoview-${geckoviewChannel}-x86_64:${geckoviewVersion}"
    armImplementation     "org.mozilla.geckoview:geckoview-${geckoviewChannel}-armeabi-v7a:${geckoviewVersion}"
    aarch64Implementation "org.mozilla.geckoview:geckoview-${geckoviewChannel}-arm64-v8a:${geckoviewVersion}"
}

Add GeckoView to a Layout

Inside a layout .xml file, add the following: 

<org.mozilla.geckoview.GeckoView
    android:id="@+id/geckoview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

Initialize GeckoView in an Activity

1. Import the GeckoView classes inside an Activity: 

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

2. In that activity's onCreate function, add the following: 

GeckoView view = findViewById(R.id.geckoview);
GeckoSession session = new GeckoSession();
GeckoRuntime runtime = GeckoRuntime.create(this);

session.open(runtime);
view.setSession(session);
session.loadUri("about:buildconfig");

You're done!

Your application should now load and display a webpage inside of GeckoView.

To learn more about GeckoView's capabilities, review GeckoView's JavaDoc or the reference application.
