Android Components > Browser > Engine-Gecko
Engine implementation based on GeckoView (Beta channel).
See concept-engine for a documentation of the abstract engine API this component implements.
Use Gradle to download the library from maven.mozilla.org (Setup repository):
implementation "org.mozilla.components:browser-engine-gecko-beta:{latest-version}"
It is recommended to create only one GeckoEngine
instance per app. To create a GeckoEngine
a GeckoRuntime
and optionally DefaultSettings
are needed.
// Create default settings (optional) and enable tracking protection for all future sessions.
val defaultSettings = DefaultSettings().apply {
trackingProtectionPolicy = EngineSession.TrackingProtectionPolicy.all()
}
// Create and initialize a Gecko runtime with the default settings.
val runtime = GeckoRuntime.getDefault(applicationContext)
// Create an engine instance to be used by other components.
val engine = GeckoEngine(runtime, defaultSettings)
Usually it is not needed to interact with the Engine
component directly. The browser-session component will take care of making the state accessible and link a Session
to an EngineSession
internally. The feature-session component will provide "use cases" to perform actions like loading URLs and takes care of rendering the selected Session
on an EngineView
.
GeckoEngineView
is the Gecko-based implementation of EngineView
in order to render web content.
<mozilla.components.browser.engine.gecko.GeckoEngineView
android:id="@+id/engineView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
GeckoEngineView
can render any GeckoEngineSession
using the render()
method.
val engineSession = engine.createSession()
val engineView = view.findViewById<GeckoEngineView>(R.id.engineView)
engineView.render(engineSession)
