How to send data to php server and get data on Android
I am new to android programming and I want to send data to php server and receive data to show in android
but i have no idea to create it, i dont want to use the library? and can provide an example for me to practice about this.
ps. sorry my english is not very good.
example Myphp "xxx.xxx.xx / api.php"
$keyword = $_GET['keyword'];
$index= $_GET['index'];
$path = "http://xxxxxxx/webservice/&query=".urlencode($keyword)."&index=".$index."";
$jsondata = file_get_contents($path);
$jsons = json_decode($jsondata,true);
echo json_encode($jsons);
I want to send keyword
and index
from edittext to php server and receive json data for list display.

HttpURLConnection can be used to receive, send, post, delete requests:
try {
// Construct the URL
URL url = new URL("http://xxxxxxx/webservice/&query="
+keyword.getText().toString()
+"&index="+index.getText().toString());
// Create the request
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("GET");
urlConnection.connect();
// Read the input stream into a String
InputStream inputStream = urlConnection.getInputStream();
StringBuffer buffer = new StringBuffer();
if (inputStream == null) {
// Nothing to do.
return null;
}
reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
while ((line = reader.readLine()) != null) {
// Since it JSON, adding a newline isn't necessary (it won't affect parsing)
// But it does make debugging a *lot* easier if you print out the completed
// buffer for debugging.
buffer.append(line + "\n");
}
if (buffer.length() == 0) {
// Stream was empty. No point in parsing.
}
JsonStr = buffer.toString(); //result
} catch (IOException e) {
}
where keyword
u index
will be your EditText variables.
