How can I get youtubeVideo Title from URL for android studio?

I want to get the youtube video title from a url so I found this code below (IOUtils) is depreciated any other way to do this
public class SimpleYouTubeHelper {
public static String getTitleQuietly(String youtubeUrl) {
try {
if (youtubeUrl != null) {
URL embededURL = new URL("http://www.youtube.com/oembed?url=" +
youtubeUrl + "&format=json"
);
return new JSONObject(IOUtils.toString(embededURL)).getString("title");
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
second way i tried
class getYoutubeJSON extends Thread {
String data = " ";
#Override
public void run() {
try {
URL url = new URL("http://www.youtube.com/oembed?url="+" https://www.youtube.com/watch?v=a4NT5iBFuZs&ab_channel=FilipVujovic"
+ "&format=json");
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
InputStream inputStream = httpURLConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = bufferedReader.readLine()) != null){
data =data + line;
}
if(!data.isEmpty()){
JSONObject jsonObject = new JSONObject(data);
// JSONArray users = jsonObject.getJSONArray("author_name");
Log.d("RT " , jsonObject.toString());
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
}
This code gets a an error Cleartext HTTP traffic to www.youtube.com not permitted
so I found this answer Android 8: Cleartext HTTP traffic not permitted but I am still getting some error I don't understand.

I solved this problem by using the volley library.
My requested url was:
String Video_id = "jhjgN2d7yok";
String url = "https://www.youtube.com/oembed?url=youtube.com/watch?v=" +Video_id+ "&format=json";

Twitter fetching application only bearer token HTTP 403 Forbidden

I am trying to fetch the application only bearer token by using my consumer key and consumer secret following this. This is my implementation:
public class OAuthApplicationOnlyBearerTokenFetchTask extends AsyncTask<String, Void, String> {
private static Logger logger =
Logger.getLogger(OAuthApplicationOnlyBearerTokenFetchTask.class.getName());
final static String URL_TWITTER_OAUTH2_TOKEN = "https://api.twitter.com/oauth2/token";
final static String USER_AGENT = "TwitterMotion User Agent";
protected String mApplicationOnlyBearerToken;
#Override
protected String doInBackground(String... tokens) {
String consumerKey = tokens[0];
String consumerSecret = tokens[0];
String encodedCredentials = encodeKeysFrom(consumerKey, consumerSecret);
HttpURLConnection urlConnection = null;
try {
URL url = new URL(URL_TWITTER_OAUTH2_TOKEN);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setDoOutput(true);
urlConnection.setDoInput(true);
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Host", "api.twitter.com");
urlConnection.setRequestProperty("User-Agent", USER_AGENT);
urlConnection.setRequestProperty("Authorization", "Basic " + encodedCredentials);
urlConnection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=UTF-8");
urlConnection.setRequestProperty("Content-Length", "29");
urlConnection.setUseCaches(false);
writeRequest(urlConnection, "grant_type=client_credentials");
String jsonResponse = readResponse(urlConnection);
logger.log(INFO, "jsonResponse of the bearer oauth request: ", jsonResponse);
if (urlConnection.getResponseCode() == HttpURLConnection.HTTP_FORBIDDEN) {
logger.log(Level.SEVERE, "HTTP 403 (Forbidden) returned from Twitter API call for bearer token. " +
"Check values of Consumer Key and Consumer Secret in tokens.properties");
throw new RejectedAuthorizationException(urlConnection.getResponseCode(), "HTTP 403 (Forbidden) returned attempting to get Twitter API bearer token");
}
JSONObject jsonResponseObject = new JSONObject(jsonResponse);
if (jsonResponseObject != null) {
mApplicationOnlyBearerToken = (String) jsonResponseObject.get("access_token");
} else {
// TODO
}
return mApplicationOnlyBearerToken;
} catch (Exception ex) {
logger.log(Level.SEVERE, "", ex);
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;
}
#Override
protected void onPostExecute(String applicationOnlyBearerToken) {
this.mApplicationOnlyBearerToken = applicationOnlyBearerToken;
}
public String getApplicationOnlyBearerToken() {
return mApplicationOnlyBearerToken;
}
private String encodeKeysFrom(String consumerKey, String consumerSecret) {
try {
String encodedConsumerKey = URLEncoder.encode(consumerKey, "UTF-8");
String encodedConsumerSecret = URLEncoder.encode(consumerSecret, "UTF-8");
String combinedEncodedKey = encodedConsumerKey + ":" + encodedConsumerSecret;
byte[] encodedBytes = Base64.encode(combinedEncodedKey.getBytes(), Base64.NO_WRAP);
return new String(encodedBytes);
}
catch (UnsupportedEncodingException e) {
// TODO
return null;
}
}
private boolean writeRequest(HttpURLConnection connection, String requestBody)
throws IOException {
BufferedWriter bufferedWriter = null;
try {
bufferedWriter = new BufferedWriter(
new OutputStreamWriter(connection.getOutputStream()));
bufferedWriter.write(requestBody);
bufferedWriter.flush();
return true;
}
catch (IOException ex) {
return false;
}
finally {
if (bufferedWriter != null) {
bufferedWriter.close();
}
}
}
private String readResponse(HttpURLConnection connection) throws IOException {
BufferedReader bufferedReader = null;
try {
StringBuilder stringBuilder = new StringBuilder();
bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
while((line = bufferedReader.readLine()) != null) {
stringBuilder.append(line + System.getProperty("line.separator"));
}
return stringBuilder.toString();
}
catch (IOException e) {
return null;
}
finally {
if (bufferedReader != null) {
bufferedReader.close();
}
}
}
}
But I am getting HTTP 403 Forbidden.
I also added permission on manifest file:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
I can not understand what is the issue actually. Thanks in advance!

Never mind, I've found the bug.
String consumerKey = tokens[0];
String consumerSecret = tokens[0];
It should be
String consumerSecret = tokens[1];

Android - Send XML file to PHP API server using HttpURLConnection

So currently, I'm trying to import some data in the form of an XML file to a server. I have successfully logged in and am doing everything through the API of the server. The website/server responds in XML, not sure if that is relevant.
When I use the import data action of the API, the request method is actually a GET and not a POST and the response content-type is text/xml. I want to strictly stick to using HttpURLConnection and I understand that sending this XML file will require some multipart content-type thing but I'm not really sure how to proceed from here.
I've looked at these two examples but it does not work for my application (at least not directly). In addition, I don't really understand where they got some of the request headers from.
Send .txt file, document file to the server in android
http://alt236.blogspot.ca/2012/03/java-multipart-upload-code-android.html
A message from one of the developers have said "To upload the data use the action=importData&gwID=nnnn and with the usual
Multipart content encoding and place the files in the request body as usual."
How would I send my XML file to my server through its API?

This is how you do it:
public void postToUrl(String payload, String address, String subAddress) throws Exception
{
try
{
URL url = new URL(address);
URLConnection uc = url.openConnection();
HttpURLConnection conn = (HttpURLConnection) uc;
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-type", "text/xml");
PrintWriter pw = new PrintWriter(conn.getOutputStream());
pw.write(payload);
pw.close();
BufferedInputStream bis = new BufferedInputStream(conn.getInputStream());
bis.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}

This is my implementation of a Multipart form data upload using HttpURLConnection.

Android app keeps failing when parsing JSON

My app makes a call to FourSquare API. The call happens in my getResponse() function, and that function gets called every time I do new Explore().execute();
Now, I am able to get a string from the API... But when I pass that string to displayResults() function, it becomes null (I have a code comment below to show exactly where). And because this string becomes null, I can not parse the JSON. What is causing this issue?
public TextView mBusinessName;
public TextView mCategorie;
public WebView mLocationView;
private class Explore extends AsyncTask<Void, String, String>{
String resp = "";
#Override
protected void onPreExecute() {
}
#Override
protected String doInBackground(Void... String) {
//I get a complete JSON string and assign to resp HERE.
resp = getResponse();
return null;
}
#Override
protected void onPostExecute(String s) {
//pass resp to display results
displayResults(resp);
}
}
public String getResponse(){
String clientSecret = getResources().getString(R.string.client_secret);
String clientID = getResources().getString(R.string.client_id);
String url = "https://api.foursquare.com/v2/venues/explore?ll="
+ mLatitude + "," + mLongitude
+ "&limit=" + 5
+ "&radius=" + mRadius
+ "&query=" + mTerm
+ "&oauth_token="
+ "&client_secret="+ clientSecret
+ "&client_id="+ clientID
+ "&v=20150610";
String getResponseString = "";
try{
URL searchUrl = new URL(url);
HttpURLConnection httpsClient =
(HttpURLConnection) searchUrl.openConnection();
BufferedReader reader = new BufferedReader(new InputStreamReader(httpsClient.getInputStream()));
try{
getResponseString = "";
while((getResponseString = reader.readLine()) != null){
Log.d("Response ==== ", getResponseString);
}
}catch (Exception e){
e.printStackTrace();
}finally {
if(reader != null){
try{
reader.close();
}catch (Exception e){
e.printStackTrace();
}
}
}
}catch (Exception e){
e.printStackTrace();
}
return getResponseString;
}
public void displayResults(String resp){
//HERE is where it fails. The String resp becomes null/empty
// have tried logging resp, the log doesn't show up at all
// because of this, JSON string can not be parsed!!!!
try {
JSONObject json = new JSONObject(resp);
JSONArray items = json.getJSONObject("response")
.getJSONArray("groups").getJSONObject(0)
.getJSONArray("items");
//randomize items
JSONObject item = items.getJSONObject(getRandomIndex(items.length()-1));
String name = item.getJSONObject("venue").optString("name");
String categorie = item.getJSONObject("venue").getJSONArray("categories").getJSONObject(0).getString("name");
String latitude = item.getJSONObject("venue").getJSONObject("location").optString("lat");
String longitude = item.getJSONObject("venue").getJSONObject("location").optString("lng");
String image = "http://maps.google.com/maps/api/staticmap?center="
+ latitude + "," + longitude
+ "&markers=size:tiny%color:red%7C" + latitude + "," + longitude
+"&zoom=17&size=375x225&sensor=false";
mLocationView.loadUrl(image);
mBusinessName.setText(name);
mCategorie.setText(categorie);
} catch (JSONException e) {
e.printStackTrace();
}
}
EDIT: The variable resp becomes null/empty inside the function displayResults(). I don't know how this is happening.

Your getResponse() method does nothing. You need to change it so that it actually returns the complete string.
try{
StringBuilder sb = new StringBuilder();
getResponseString = "";
while((getResponseString = reader.readLine()) != null){
Log.d("Response ==== ", getResponseString);
sb.append(getResponseString);
}
}catch (Exception e){
e.printStackTrace();
}finally {
if(reader != null){
try{
reader.close();
}catch (Exception e){
e.printStackTrace();
}
}
}
return sb.toString();

Oauth Authorization issue while integrating web app with Quickbooks

Is not a valid URL, and it needs to be. Fix your URL.
