Class XWalkExternalExtensionManager

java.lang.Object

org.xwalk.core.XWalkExternalExtensionManager

public abstract class XWalkExternalExtensionManager
extends java.lang.Object

XWalkExternalExtensionManager represents an external extension manager. Its instance would be created While constructing XWalkView. XWalkView embedders could get the manager by calling XWalkView.getExtensionManager(), and then employ the manager to load their own external extensions by path, although XWalkView embedders must package their external extensions into the apk beforehand.

What would XWalkView embedders do:
 1, package extension MyExtension.js/json files into apk folder assets/xwalk-extensions/MyExtension.
 2, package MyExtension.jar into apk.
 3, add permissions required by MyExtension into AndroidManifest.xml.
 4, call XWalkView.getExtensionManager().loadExtension("xwalk-extensions/MyExtension") to load.
 

In embedded mode, developers can call XWalkView.getExtensionManager() to load extensions directly after the creation of XWalkView. But in shared mode and lite mode, the Crosswalk runtime isn't loaded yet at the moment the activity is created, so can't load extensions immediately. To make your code compatible with all modes, please refer to the examples in XWalkActivity or XWalkInitializer to make sure to load extensions after XWalk runtime ready.
