Cosume PHP(POST METHOD) webservice in android.

Here i am passing json string parameter to php webservice. To consume php post method we will use HttpPost.

To create JSON String in android:

JSONObject json = new JSONObject();

json.put("name", "");
json.put("email", "");
json.put("password", "");

Log.i("json Object", json.toString());

Pass the parameter to post method:

        List<NameValuePair> params = new ArrayList<NameValuePair>();

        params.add(new BasicNameValuePair("userinfo", json.toString()));

Get the response InputStream like this:

HttpResponse response;
InputStream is = null;

   response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
is = httpEntity.getContent();

Full Code:

HttpResponse response;
JSONObject json = new JSONObject();
String json1 = "";
JSONObject jObj = null;
InputStream is = null;

DefaultHttpClient client = new DefaultHttpClient();

try {
HttpPost post = new HttpPost(
"Your URL");
json.put("name", "");
json.put("email", "");
json.put("password", "");

Log.i("jason Object", json.toString());
post.setHeader("userinfo", json.toString());

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("userinfo", json.toString()));

post.setEntity(new UrlEncodedFormEntity(params));
response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
is = httpEntity.getContent();

try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
}
is.close();
json1 = sb.toString();
Log.i("jason Object", sb.toString());

Log.e("JSON", json1);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json1);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}

// return JSON String

Log.d("final Response", jObj.toString());
Log.d("status", jObj.getString("status")); //Declare your status or message or json string variable

} catch (Exception e) {
e.printStackTrace();
}

HttpResponse to String android

Manifest.xml:

Add the following line in your manifest.
<uses-permission android:name="android.permission.INTERNET"/>

Note:
In AVD to connect to localhost you need to use urlhttp://10.0.2.2/ instead of http://localhost/.

Cosume PHP(GET METHOD) webservice in android.

Here i am going to show you the exact code for cosume php webservice in android. But in this example i have passes emailid and password in the url to check whether the user is valid or not.
To consume php get method we will use HttpGet.

Get the response InputStream like this:

InputStream is = null;

HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();

Full Code:

  InputStream is = null;
JSONObject jObj = null;
String json = "";

       //Place your own url here
String URL = "http://domain.com/login.php?email="
+ username.getText().toString().trim().toLowerCase()
+ "&password="
+ password.getText().toString().trim().toLowerCase() + "";

   Log.d("username", username.getText().toString().trim()
   .toLowerCase());
   Log.d("password", password.getText().toString().trim()
   .toLowerCase());

   // Making HTTP request
   // (http://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/)

   try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(URL);

Log.d("pre", URL);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();

   } catch (UnsupportedEncodingException e) {
e.printStackTrace();
   } catch (ClientProtocolException e) {
e.printStackTrace();
   } catch (IOException e) {
e.printStackTrace();
   }

   try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
   sb.append(line + "n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
   } catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
   }

   // try parse the string to a JSON object
   try {
jObj = new JSONObject(json);
   } catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
   }

   // return JSON String

   Log.d("test", jObj.toString());
