java - How to execute JavaScript on Android?

Question

I have code which uses ScriptEngineManager, ScriptEngine class for executing JavaScript code using Java. But it works fine in Java SE, and doesn't work in Android - SDK show error of missing classes. Is it possible to execute JS code in Android? Thank you.

AndroidJSCore is a great one. And here is another little library I wrote for evaluating JavaScript:

https://github.com/evgenyneu/js-evaluator-for-android

jsEvaluator.evaluate("function hello(){ return 'Hello world!'; } hello();", new JsCallback() {
  @Override
  public void onResult(final String result) {
    // get result here (optional)
  }
});

It creates a WebView behind the scenes. Works on Android version 3 and newer.
