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.
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);
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
You can use URLConnection with setDoOutput(true), getOutputStream() (for sending data), and getInputStream() (for receiving). Sun has an example for exactly this.
I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
