In most of the android applications it is essential that app may need to connect to internet and make some HTTP requests. In this article i’ll be demonstrating about making simple HTTP Requests in android.
Below are the code snippets to handle HTTP requests.
Creating HTTP Client and HTTP Post
// Creating HTTP client HttpClient httpClient = new DefaultHttpClient(); // Creating HTTP Post HttpPost httpPost = new HttpPost("http://www.example.com/login");
Bulding Post Parameters
The following code will create post parameters pair with key and value.
// Building post parameters, key and value pair List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2); nameValuePair.add(new BasicNameValuePair("email", "user@gmail.com")); nameValuePair.add(new BasicNameValuePair("password", "encrypted_password"));
URL Encoding POST data
Before making HTTP request you need to encode the post data in order to convert all string data into valid url format.
// Url Encoding the POST parameters try { httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair)); } catch (UnsupportedEncodingException e) { // writing error to Log e.printStackTrace(); }
Finally making HTTP Request
Finally you need to execute httpPost using the httpClient created before.
// Making HTTP Request try { HttpResponse response = httpClient.execute(httpPost); // writing response to log Log.d("Http Response:", response.toString()); } catch (ClientProtocolException e) { // writing exception to log e.printStackTrace(); } catch (IOException e) { // writing exception to log e.printStackTrace(); }
Final Code
The following is the final code to make http Requests. I am writing response to log. Check your Log report in Eclipse to see your http response.
package com.androidhive.httprequests; import java.io.IOException; import java.io.UnsupportedEncodingException; import java.util.ArrayList; import java.util.List; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import android.app.Activity; import android.os.Bundle; import android.util.Log; public class AndroidHTTPRequestsActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Creating HTTP client HttpClient httpClient = new DefaultHttpClient(); // Creating HTTP Post HttpPost httpPost = new HttpPost( "http://www.example.com/login"); // Building post parameters // key and value pair List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2); nameValuePair.add(new BasicNameValuePair("email", "user@gmail.com")); nameValuePair.add(new BasicNameValuePair("message", "Hi, trying Android HTTP post!")); // Url Encoding the POST parameters try { httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair)); } catch (UnsupportedEncodingException e) { // writing error to Log e.printStackTrace(); } // Making HTTP Request try { HttpResponse response = httpClient.execute(httpPost); // writing response to log Log.d("Http Response:", response.toString()); } catch (ClientProtocolException e) { // writing exception to log e.printStackTrace(); } catch (IOException e) { // writing exception to log e.printStackTrace(); } } }
Ravi is hardcore Android programmer and Android programming has been his passion since he compiled his first hello-world program. Solving real problems of Android developers through tutorials has always been interesting part for him.
[…] is combination of some of my previous tutorials. I hope you covered these tutorials before. Android making HTTP Requests Android JSON Parsing Tutorial Android SQLite Database Tutorial Android Login and Registration […]
what is the procedure to access the “remote database of website” please help….
Hi Ravi,
How may I connect with username and password to my website’s login…?
your motherfucker, HIJO DE PUTA
fack comment……………………
This is not a tutrial, It’s an example.
While I appreciate “tutorial” posting I absolutely agree with dinosaurclover that this is more of an “example” than true tutorial.
Add this if not working:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
Guys can i pass a String array in the Basic name value pair..if not then can you suggest some alternatives….help!!
I downloaded your project and runs normal, but in my otros projects where the error on the line:
HttpResponse response = httpClient.execute (HttpPost);
wats the output of this example.?
Thanks for the post. I am trying to post a string array.
My code:
for(String attachment : attachments){
multipartEntity.addPart(“attachments[]”, new StringBody(attachment));
}
It is not working for me. server received full array as string( example “[“a”, “b”]” ). but I have to pas only string array (example- [“a”,”b”] ). Please help.
It’s very helpful. May know how to do the PUT and DELETE methods though
Hello Ravi. I’m trying to download the source code, but when I subscribe my e-mail I NEVER receive the confirmation in my e-mail, I already verify my spam box and tried another e-mail.
Please check your SPAM folder.
As I said before, I’ve checked the spam folder from my two emails. =/
Ok. If you have Gmail account please try with that email id.
Works perfectly! I downloaded and all is working, but I can’t download this: http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/ maybe the link is broken.
Thanks Ravi.
Please check your SPAM folder for activation email.
can we do it for local server in our machine

Your tutorials are the most easy to understand tutorials in this planet. I learnt many concepts here. I want you to explain about what are web services, Different types of web services, methods used, creating a web service in java, how a web service receives request (HTTP, SOAP,REST etc. Not even one of them is understood by me), difference between a web service and servlet, how to create Database, save data in database via servelet/web service/ android application. Sorry as the list is too long. But I really liked the way you explain, and can easily understand. By the way I too live in Hyderabad
Thanks Prasad. Happy Coding 🙂
how can i post my data?
{ “OrgID”:”1″,
“UserDepartment”:”1″,
“WorkType”:”1977″,
“WorkDefinition”:”EXAMPLE_EXAMPLE”,
“Confirmed”:[

{“Confirmed”:”qaAgo/+/j/XhECIhlAo2SQ==”}],
“FileName”:””,
“FileMimeType”:””,
“FileContent”:””
}
i write this codes but i couldn’t post
public static void sendParameter(String organizationId, String departmentId, String workType, List comfirmedList, String fileName, String fileMimeType, String fileContent, String definition) {
parameterList = new ArrayList();
parameterList.add(new BasicNameValuePair(“OrgID”, organizationId));
parameterList.add(new BasicNameValuePair(“UserDepartment”, departmentId));
parameterList.add(new BasicNameValuePair(“WorkType”, workType));
parameterList.add(new BasicNameValuePair(“Confirmed”, String.valueOf(comfirmedList)));
parameterList.add(new BasicNameValuePair(“FileName”, fileName));
parameterList.add(new BasicNameValuePair(“FileMimeType”, fileMimeType));
parameterList.add(new BasicNameValuePair(“FileContent”, fileContent));
parameterList.add(new BasicNameValuePair(“WorkDefinition”, definition));
}
Thanks for put this tutorial.
but HttpClient is not working in my project for that what can i do?
Is there any library which put in gradle.build ? or package or Build Tools which i not installed ?
Thanks in advance.
Please follow this tutorial. You can use String Request mentioned in this article to make a http request.

sir , i want to post data to server in json format using the same service handler class you have used in json parsing tutorial.. and i am getting trouble with this parameter List params can you plz help me out
Your tutorials are the best and easiest to understand.. however as httpclient is now depricated in latest android builds can you help me with this particular piece of code? I’ve tried a lot to convert this into httpurlconnection it simply doesnt work for me…
HttpClient httpClient = new DefaultHttpClient();
// Creating HTTP Post
HttpPost httpPost = new HttpPost(link);
//Name value pair created what you want to send to server
List nameValuePair = new ArrayList(2);
nameValuePair.add(new BasicNameValuePair(“Languages”,lang));
nameValuePair.add(new BasicNameValuePair(“voice”,vc));
nameValuePair.add(new BasicNameValuePair(“ex”,”execute”));
nameValuePair.add(new BasicNameValuePair(“op”,text));
nameValuePair.add(new BasicNameValuePair(“count”,count));
nameValuePair.add(new BasicNameValuePair(“speed”,speed));
//httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair, “UTF-8”)); // UTF 8 added to send indic string to server
HttpResponse httpResponse = httpClient.execute(httpPost);
final int statusCode = httpResponse.getStatusLine().getStatusCode();
Log.d(“Response Status Code”,String.valueOf(statusCode));
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
and this is what i have coded for the httpurlconnection:
URL url = new URL(link);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setReadTimeout(10000);
urlConnection.setConnectTimeout(15000);
urlConnection.setRequestMethod(“POST”);
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setChunkedStreamingMode(0);
urlConnection.setInstanceFollowRedirects(false);
urlConnection.setRequestMethod(“POST”);
Map param = new LinkedHashMap();
param.put(“Languages”, lang);
param.put(“voice”,vc);
param.put(“ex”,”execute”);
param.put(“op”,nt);
param.put(“count”,count);
param.put(“speed”,speed);
StringBuilder postData = new StringBuilder();
for (Map.Entry param1 : param .entrySet()) {
if (postData.length() != 0) postData.append(‘&’);
postData.append(URLEncoder.encode(param1.getKey(), “UTF-8”));
postData.append(‘=’);
postData.append(URLEncoder.encode(String.valueOf(param1.getValue()), “UTF-8”));
}
byte[] postDataBytes = postData.toString().getBytes(“UTF-8”);
int postDataLength = postDataBytes.length;
urlConnection.setRequestProperty( “charset”, “utf-8”);
urlConnection.setRequestProperty( “Content-Length”, Integer.toString( postDataLength ));
urlConnection.setUseCaches(false);
urlConnection.getOutputStream().write(postDataBytes);
Log.d(“getoutputstream”, postDataBytes.toString());
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
// readStream(in);
InputStreamReader isr = new InputStreamReader(in);
BufferedReader br = new BufferedReader(isr);
str = br.readLine();
Log.d(“output of str”,str);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
urlConnection.disconnect();
}
Please tell me what I am doing wrong?

Using HttpPost and NameValuePair is deprecated. So what should we use now?
Try using Retrofit or Volley. This is just a basic tutorial.
https://www.androidhive.info/2016/05/android-working-with-retrofit-http-library/
https://www.androidhive.info/2014/05/android-working-with-volley-library-1/
Is it possible to post data on a localhost using HttpUrlConnection and OutputStreamWriter?
Hi,
Great post, are you planning to write sth about xml/json parsing ?
HI moczul,
Those articles will be soon….
can work on android 1.5 version?
I haven’t tried … but it should work.
Hi Ravi, can u tell me what kind of android build target for all your tutorial, thanks for reply
I used Android 2.2 target for all my tutorials.
Sorry, i have another questions, i start to develop a audience response system for my website and android mobile device, the website should let presenter create some questions such as MC, LQ, open end question, checkbox question,etc in a session (polling) and users can join that session to vote their choices,
and for android mobile users, they can join that session to vote questions. for my questions are.. should i use JSON or XML to store questions list in my website in MYSQL database and what technology must implement to let mobile user to join session and during the session user can vote their choices based on current questions, sorry for my stupid question, but i have no ideas about android technology
Hi Ravi, also i wanna know the difference between the value of fill_parent and match_parent, i confuse this two
both do same job, but from API Level +8 fill_parent is deprecated. You have to use match_parent only.
Hi Ravi, can u give me some ideas for my below questions, thanks
Ravi, please give me a direction of this situation, just should i use JSON or XML to store questions list in my website in MYSQL database and what technology must implement to let mobile user to join session and during the session user can vote their choices based on current questions, sorry for my stupid question, but i have no ideas about android technology~thanks
Use JSON for your application as it is more flexible than XML. Just send a request from mobile to get all questions. From mobile if user votes a question just send question id along with user id to your api. There change in your database of the question (vote up / down question by user id)
but, should i store JSON file in database coloum (store the path of file) or is there else other alternative to store questions list file? thanks for reply
We should not store JSON in database. Store only questions in database. When required get the questions from database and generate the json on the fly and echo.
If you are using PHP get the data from database. Store them in Array in convert array into json using json_encode($your_array) function. Google about converting array to json in php.
but, u said that i cant store JSON in database, Store only questions in database that mean pain text file’s path on the server??
I mean question in database table like
table structure
——————-
qid | question | created_at
1. | Your question | 12:30 PM 12-12-2011
but if there are many questions in a session, that mean i should store every question record in question table and then use get all questions about that session and convert TO JSON, then , form mobile just make request and parse JSON ?
Coincidentally, I am implementing a project to simplify the HTTP request model for Android. It’s an open source project that you can find here:
https://github.com/hrj/SafeNet
Hi,
I was trying to implement similar code to log in https page and display response content in webView but it seems to fail? have you any idea why?
StrictMode is enabled by default in Android 3.0 and above. Hence, this code might not work. You have to do this in a separate Thread or even better an AsyncTask.
Thanks for the information.
i had a doubt about making http requests to gmail…
my app stores the login details of gmail account.
wat i wanna do is whn user clicks on the login , it must automatically login into gmail & show his inbox in the browser.
m really new to android…please help
You need to implement OAuth to connect to gmail:
http://googlecode.blogspot.in/2010/03/oauth-access-to-imapsmtp-in-gmail.html
I was getting errors from debugger until I added
in my AndroidManifest.xml.
dear ravi this is only post the data right how can i give read the data in smae file. like sucess message.
I didn’t get you clearly. Could you explain me better ?
dear ravi i am able to post the data but when i given the success message it’s not display like
I think that your question could be solved by the following code.
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null)
{
str.append(line);
}
in.close();
String html = str.toString();
hi Ravi i tried ur code but it doesnt work and keeps giving an error, i also added a uses-permission for the internet , but it still gives me an error , kindly suggest a solution
Make sure that you added permission outside tag not inside. If you did correctly please check for your error log cat report.
hi this is how my manifest loks like…kindly suggest wat is wrong
It seems to be correct. Check your error log report.
Windows -> Show View -> Other -> Android -> Log Cat
the application crashes…is tht suppose to happen ??
this is the logcat i get

Hi fedo,
I gave an example of email and password field. You can send whatever data you want, that depends on your app requirement. Please check for Permissions in you AndroidManifest.xml file.
the application wil send an email to my email box ? – It won’t send email to your email box. It is an example of when user log into their application i am sending their email and password to a online server. There you need to check email and password are in database. if yes send success response to client mobile or send fail response.
I think i missed one point in this tutorial. Add internet permission in your androidmanifest.xml file after tag
Then also if it don’t work give me your error log cat.
