Can I Fetch Data From URL Using POST Method In Android?

I want to fetch data from a URL using the POST method. I already fetched data using the GET method. Now I want to do it with the POST method. When I click on the button I don't get

Solution 1:

Use this for POST request using HttpURLConnection, you can add or remove properties based on your requirement:

URL url = new URL("http://yoururl.com");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setReadTimeout(7000);
conn.setConnectTimeout(10000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("param1", paramValue1));
params.add(new BasicNameValuePair("param2", paramValue2));

OutputStream outputStream = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
        new OutputStreamWriter(outputStream, "UTF-8"));
writer.write(getQuery(params));
writer.flush();
writer.close();
outputStream.close();

conn.connect();

Here is getQuery() method :

private String getQuery(List<NameValuePair> params) throws UnsupportedEncodingException
{
    StringBuilder result = new StringBuilder();
    boolean first = true;

    for (NameValuePair pair : params)
    {
        if (first)
            first = false;
        else
            result.append("&");

        result.append(URLEncoder.encode(pair.getName(), "UTF-8"));
        result.append("=");
        result.append(URLEncoder.encode(pair.getValue(), "UTF-8"));
    }

    return result.toString();
}
