Parsing jsoup url android

Parsing jsoup url android - java

I can parse an href url just following the documentation:
Document doc = Jsoup.connect("http://jsoup.org").get();
Element link = doc.select("a").first();
String relHref = link.attr("href"); // == "/"
String absHref = link.attr("abs:href"); // "http://jsoup.org/"
but i try to extract a link url from css in this webpage: http://multiplayer.it/notizie/133685-assassins-creed-unity-ecco-come-assassins-creed-unity-sfrutta-lhardware-di-nuova-generazione.html
i need take the link of image banner. The id is: id="content_heading" but the image is loaded by css.
<div id="content_heading" style="background: url(http://images.multiplayer.it/thumbs/images/2014/06/10/assassins_creed_unity_jpg_1600x0_upscale_q85.jpg) center center; background-size: cover;">
How can i extract the url? this is the Asynktask
private class ContentViewImgUrl extends AsyncTask<String,String,String> {
#Override
protected void onPreExecute()
{
}
#Override
protected String doInBackground(String... params) {
try {
final Document doc = Jsoup.connect(URL).timeout(30000).get();
runOnUiThread(new Runnable() {
#Override
public void run() {
Element rootElement = doc.body().getElementById("top_ads_container");
Elements elements = rootElement.getElementsByTag("header");
for(Element element : elements){
imgUrlPost = element.select("div.content_heading").text();
}
}
});
} catch (Exception e) {
Log.e("ESEMPIO", "ERROR");
}
return null; // MODIFIED HERE
}
#Override
protected void onPostExecute(String result)
{
Toast.makeText(SingleActivity.this, "url "+ imgUrlPost, Toast.LENGTH_SHORT).show();
}
}
The toast not works.. It returns only Url and nothing else.
Thanks
UDPATE:
private class ContentViewImgUrl extends AsyncTask<Void,Void,Void> {
final Pattern pattern = Pattern.compile("url\\((.+?)\\)");
#Override

where urlnew i declared it as public URL urlnew and postBitmap as Bitmap

final Pattern pattern = Pattern.compile("url\\((.+?)\\)");
try {

Matcher matcher = pattern.matcher(url);

}
The error I get is;
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.wowza.gocoder.sdk.sampleapp/com.wowza.gocoder.sdk.sampleapp.PlayerActivity}: java.lang.RuntimeException: Invalid surface: null

You start the stream in onCreate. At this time the Surface used by WOWZPlayerView is not ready yet and the app crashes with the 'Invalid surface' error.
If you look at the sample test in the GoCoder SDK, the playback is started when the user clicks a button. Eg. when the Surface is valid.
Create a button and move your 'mStreamPlayerView.play(mStreamPlayerConfig, statusCallback);' to the button.onClick.
Or ... use any GoCoder SDK v1.7 and more recent.
Please, let me know if I can help any further.
Thanks

Unable to access string from class

I want to show string from another string in my MainActivity, but the string is getting printed in console. Here is my code:
public class MainActivity extends AppCompatActivity {
Button start;
public TextView showText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showText= (TextView)findViewById(R.id.textView);
start = (Button)findViewById(R.id.button);
start.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RetrieveFeedTask click1 = new RetrieveFeedTask();
click1.execute();
showText.setText(click1.getString());
}
});
}
}
And the class:
class RetrieveFeedTask extends AsyncTask<Void, Void, String> {
static final String API_URL = "http://numbersapi.com/random/trivia?json";
private Exception exception;
public String finalString;
protected void onPreExecute() { }
protected String doInBackground(Void... urls) {
try {
URL url = new URL(API_URL );
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
try {
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
StringBuilder stringBuilder = new StringBuilder();
while ((finalString = bufferedReader.readLine()) != null) {
stringBuilder.append(finalString).append("\n");
}
bufferedReader.close();
return stringBuilder.toString();
}
finally{
urlConnection.disconnect();
}
}
catch(Exception e) {
Log.e("ERROR", e.getMessage(), e);
return null;
}
}
protected void onPostExecute(String response) {
if(response == null) {
response = "THERE WAS AN ERROR";
}
try {
JSONObject object = (JSONObject) new JSONTokener(response).nextValue();
finalString = object.getString("text");
Log.i("Here",finalString);
} catch (JSONException e) {
}
}
public String getString() {
return this.finalString;
}
}

You require the finalString before it's populated with your data. the onPostExecute is executed after the doInBackground so you should pass your text view to your task and set it's value in the onPostExecute
public TextView showText;
public RetrieveFeedTask(TextView showText) { this.showText = showText; }
protected void onPostExecute(String response) {
if(response == null) {
response = "THERE WAS AN ERROR";
}
try {
JSONObject object = (JSONObject) new JSONTokener(response).nextValue();
finalString = object.getString("text");
showText.setText(finalString ); // add this
Log.i("Here",finalString);
} catch (JSONException e) {
}
}

The problem is that showText.setText(click1.getString()); of your activity is called earlier than finalString = object.getString("text"); of your task.
Solution:
Create an interface:
public interface DataCallback {
void onNewData(String data);
}
and implement it in your activity:
public class MainActivity extends ... implements DataCallback
public void onNewData(String data) {
showText.setText(data);
}
Pass the interface to your asynctask when you create it:
RetrieveFeedTask click1 = new RetrieveFeedTask(this);
Call the interface inside the task in onPostExecute() to notify the activity that there is new data:
JSONObject object = (JSONObject) new JSONTokener(response).nextValue();
finalString = object.getString("text");
callback.onNewData(finalString);

How to play Youtube url in WebView or VideoView

I simply want to play youtube url in WebView or VideoView. Suppose this . I have followed number of tutorials.But I am unable to find a way.
WebViewActivity
In onCreate()
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setPluginState(PluginState.ON);
// webView.getSettings().setPluginsEnabled(true);
final Activity activity = this;
webView.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view , int progress)
{
// Activities and WebViews measure progress with different
// scales.
// The progress meter will automatically disappear when we reach
// 100%
activity.setProgress(progress * 1000);
}
});
webView.setWebViewClient(new MyOwnWebViewClient());
webView.loadData(playVideo, "text/html", "utf-8");
//webView.loadUrl("http://www.androidbegin.com/tutorial/AndroidCommercial.3gp");
//webView.loadUrl("file:///android_asset/Videos/" + extra + ".htm");
webView.setWebViewClient(new MyOwnWebViewClient());
And MyOwnWebViewClient is
public class MyOwnWebViewClient extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view , String url)
{
view.loadUrl(url);
return true;
}
}
VideoActivity
In onCreate()
