Send post data in android

Question

I'm experienced with php, javascript and a lot of other scripting languages, but I don't have a lot of experience with java or android.

I'm looking for a way to send POST data to a PHP script and display the result.

Answer 1

You can use URLConnection with setDoOutput(true), getOutputStream() (for sending data), and getInputStream() (for receiving). Sun has an example for exactly this.

Answer 2

Better use Apache Commons HttpClient, that is also included in android already. Have a look at http://developer.android.com/reference/org/apache/http/client/package-summary.html for general api info.

Plenty of examples are provided here: http://hc.apache.org/httpcomponents-client/examples.html

Answer 3

Http Client from Apache Commons is the way to go. It is already included in android. Here's a simple example of how to do HTTP Post using it.

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://www.yoursite.com/script.php");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("id", "12345"));
        nameValuePairs.add(new BasicNameValuePair("stringdata", "Hi"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}
