<a onClick="window.demo.clickOnAndroid()">

<img id="droid" src="jqtouch.png" mce_src="jqtouch.png" /><br>

Click me!

</a>

<a href="page1.html" mce_href="page1.html">page1</a>

package com.geolo.android;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.webkit.WebChromeClient;

    private Handler mHandler = new Handler();

    private WebView mWebView;

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        mWebView = (WebView)findViewById(R.id.webView01);

        mWebView.getSettings().setJavaScriptEnabled(true);

        mWebView.setWebChromeClient(new WebChromeClient());

        mWebView.addJavascriptInterface(new Object() {

            public void clickOnAndroid() {

                mHandler.post(new Runnable() {

                    public void run() {

                        mWebView.loadUrl("javascript:wave()");

                    }

                });

            }

        }, "demo");



        mWebView.loadUrl("file:///android_asset/sample/index.html");

    }

}
