Android媒体播放器返回IllegalStateException

我有以下代码来播放小型音频文件

private void playVoice() {

     if (mPlayVoice != null) {
         if (mPlayVoice.isPlaying()) {
             mPlayVoice.release();
             mPlayVoice = null;
         }
     }
     mPlayVoice = 
         MediaPlayer.create(BirdsActivity.this, mSoundIds[getCurrentIndex()]);
     mPlayVoice.start();
 }

它在三星galaxy选项卡中工作正常,但在小型设备中出现以下错误(我在索尼xperia mini pro检查了我的项目)

弹出窗口无法打开在webview中？

我目前正在使用webview,其中在webview中单击某个按钮时会创建Javascript弹出窗口.但它并没有在我的Webview中打开.

我的代码在这里:

wvPayements = (WebView) view.findViewById(R.id.wvPaymentsPage);
    wvPayements.getSettings().setLoadWithOverviewMode(true);
    wvPayements.getSettings().setUseWideViewPort(true);
    wvPayements.getSettings().setSupportZoom(true);
    wvPayements.getSettings().setAllowFileAccess(true);
    wvPayements.getSettings().setJavaScriptEnabled(true);
    wvPayements.getSettings()
            .setJavaScriptCanOpenWindowsAutomatically(true);
    wvPayements.getSettings().setBuiltInZoomControls(true);
    wvPayements.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }

        @Override
        public void onPageFinished(WebView view, final String url) {
            dialog.cancel();
        }
    });
     wvPayements
     .loadUrl("http://192.168.0.114/Parch_ws/testalert.html");

org.apache.harmony.xml.ExpatParser $ ParseException(无效令牌)

我正在使用以下两种方法来解析我的Xml数据:

private static XMLReader prepareSAX() throws ParserConfigurationException,
        SAXException {
    SAXParserFactory spf = SAXParserFactory.newInstance();
    SAXParser sp = spf.newSAXParser();

    return sp.getXMLReader();
}
public static void LectorSAX(XMLReader xr, String url) {
    try {

        InputSource is = new InputSource(url);
        is.setEncoding("UTF-8");
        xr.parse(is);
    } catch (SAXException e) {
        System.err.println("Error de sax LectorSAX.java: " + e);
        e.printStackTrace();
    } catch (IOException e) {
        System.err.println("Error de  io LectorSAX.java: " + e);
        e.printStackTrace();
    }
}
