How can I open Android browser with specified POST parameters?

In my Android application, I need to open a link in Browser. This page can receive some data just via POST. Could I add these parameters (data) to the intent which start the browser?

Do you know if this is possible? If it is, could you give my a hint?

Use a webview:

WebView webview = new WebView(this);
setContentView(webview);
byte[] post = EncodingUtils.getBytes("postvariable=value&nextvar=value2", "BASE64");
webview.postUrl("http://www.geenie.nl/AnHeli/mobile/ranking/demo/index.php", post);

Intents sent to the browser can contain more than just a URL. In older versions of android it was possible to package extra POST data in the intent, in newer versions that capability is gone but one can send extra header data for a GET (which can be just about anything representable as a string) in the intent delivered to the browser.

try{
        String finalUrl = "javascript:" +
                "var to = 'http://the_link_you_want_to_open';" +
                "var p = {param1:'"+your_param+"',param2:'"+your_param+"'};" +
                "var myForm = document.createElement('form');" +
                "myForm.method='post' ;" +
                "myForm.action = to;" +
                "for (var k in p) {" +
                "var myInput = document.createElement('input') ;" +
                "myInput.setAttribute('type', 'text');" +
                "myInput.setAttribute('name', k) ;" +
                "myInput.setAttribute('value', p[k]);" +
                "myForm.appendChild(myInput) ;" +
                "}" +
                "document.body.appendChild(myForm) ;" +
                "myForm.submit() ;" +
                "document.body.removeChild(myForm) ;";


        Uri uriUrl = Uri.parse(finalUrl);
        Intent browserIntent = new Intent(Intent.ACTION_VIEW);
        PackageManager packageManager = this.getPackageManager();
        browserIntent.setData(uriUrl);
        List<ResolveInfo> list = packageManager.queryIntentActivities(browserIntent, 0);
        for (ResolveInfo resolveInfo : list) {
            String activityName = resolveInfo.activityInfo.name;
            if (activityName.contains("BrowserActivity")) {
                browserIntent =
                        packageManager.getLaunchIntentForPackage(resolveInfo.activityInfo.packageName);
                ComponentName comp =
                        new ComponentName(resolveInfo.activityInfo.packageName, resolveInfo.activityInfo.name);
                browserIntent.setAction(Intent.ACTION_VIEW);
                browserIntent.addCategory(Intent.CATEGORY_BROWSABLE);
                browserIntent.setComponent(comp);
                browserIntent.setData(uriUrl);
            }
        }

        this.startActivity(browserIntent);

    }catch (Exception e){
        e.printStackTrace();
        txtHeader.setText(e.toString());
    }
