JavaScript - Rhino Android Library - Invoking in Android Code

Question

I am using rhino-android library to invoke java script code in java but I am not getting how to handle callback in javascript in java.

Java script code

   function TestingFunction(data, callback ){
        callback(data);
    }

I am trying to invoke the same in java- Android code

invocable.invokeFunction("TestingFunction","12345", ?(How to handle callback))

Can anyone suggest how to handle callback from javascript in java code?

Answer 1

Passing a Java callback to a JavaScript function in Rhino should be possible by implementing the org.mozilla.javascript.Function interface, something like this:

invocable.invokeFuntion("TestingFunction", "12345", 
      new org.mozilla.javascript.Function() {

    @Override
    public Object call(Context cx, Scriptable scope, Scriptable thisObj,
          Object[] args) {

        String data = (String) args[0];
        // do stuff...
    });
