我试图从HTML5canvas将图像(JPEG)保存到桌面.我可以在新窗口中打开window.open(canvas.toDataURL('png'), "");,但如何将其保存到桌面？谢谢.

protected class saveBtnClickHandler implements OnClickListener{
    @Override
    public void onClick(View v) {
           String jsonRest = loadJsonDataFromURL("http://thirddhaba.appspot.com/api/v1/circle/condensed/data/?circle_id=1");
    try {
            JSONObject jsonObj = new JSONObject(jsonRest);  

        } catch (JSONException e) {
              android.util.Log.e("JSON Parser", "Error parsing data " + e.toString());
        }
    }
}

protected String loadJsonDataFromURL(String url){
     String jsonStr = null;
    try {
         HttpClient httpclient = new DefaultHttpClient();
            HttpResponse response = httpclient.execute(new HttpGet(url));
            StatusLine statusLine = response.getStatusLine();
            if(statusLine.getStatusCode() == HttpStatus.SC_OK){
                ByteArrayOutputStream out = new ByteArrayOutputStream();
                response.getEntity().writeTo(out);
                out.close();
                 jsonStr = out.toString();

            } else{
                //Closes the connection. …
