Public Methods

public static void installBridge ()

This method must be called very early (eg: before webviews are loaded in your app). GoogleInstrumentation invokes this method if this library is present on your classpath.

This method must be called from the main thread. It'll return immedately if the bridge is already installed.

public static Conduit makeConduit ()

Creates a Conduit object which allows Java to wrap Javascript code within a handler that will foward evaluation results back to the Java process.

Conduits can be used for only 1 evaluation. Creating new ones is relatively cheap.
