how to play vimeo video using iframe in webview?

Question

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView wv=(WebView)findViewById(R.id.webView1);

        wv.getSettings().setJavaScriptEnabled(true);
        wv.getSettings().setAppCacheEnabled(true);
        wv.getSettings().setDomStorageEnabled(true);

        // how plugin is enabled change in API 8
        if (Build.VERSION.SDK_INT < 8) {
          wv.getSettings().setPluginsEnabled(true);
        } else {
          wv.getSettings().setPluginState(PluginState.ON);
        }
        String venkat="<iframe src=\"http://player.vimeo.com/video/27244727?portrait=0&color=333\" width=\"WIDTH\" height=\"HEIGHT\" frameborder=\"0\" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>";
        wv.loadData(venkat,"text/html","UTF-8");
    }
}

After researching from google I have written the above code but is not working. In this no errors are occurred but when I click on the play button progress bar is displaying for sometime and then it disappears and displays play button again... Could anyone please suggest me how to solve this problem?
