Hi I am developing android app using java restfull webservices Here I am getting one issue in calling web service through post method when I use client.post("") my all values get null while calling webservice. I dont know why it is happening. And when I use client.get("") its working properly.And I am able to do register properly through client.get. But I want to use client.post Please help me let me know what I am mistaking.
public void registerUser(View view){
String name = nameET.getText().toString();
String email = emailET.getText().toString();
String password = pwdET.getText().toString();
RequestParams params = new RequestParams();
if(Utility.isNotNull(name) && Utility.isNotNull(email) && Utility.isNotNull(password)){
if(Utility.validate(email)){
control
params.put("name", name);
params.put("username", email);
params.put("password", password);
// Invoke RESTful Web Service with Http parameters
invokeWS(params);
}
}
public void invokeWS(RequestParams params){
System.out.println("params===== "+params);
prgDialog.show();
**AsyncHttpClient client = new AsyncHttpClient();
client.post("http://localhost:8080/DemoForAndroid/register/doregister",params ,new AsyncHttpResponseHandler()** {
// When the response returned by REST has Http response code '200'
public void onSuccess(String response) {
// Hide Progress Dialog
System.out.println("response======= "+response);
prgDialog.hide();
try {
// JSON Object
JSONObject obj = new JSONObject(response);
// When the JSON response has status boolean value assigned with true
if(obj.getBoolean("status")){
// Set Default Values for Edit View controls
setDefaultValues();
// Display successfully registered message using Toast
Toast.makeText(getApplicationContext(), "You are successfully registered!", Toast.LENGTH_LONG).show();
}
// Else display error message
else{
errorMsg.setText(obj.getString("error_msg"));
Toast.makeText(getApplicationContext(), obj.getString("error_msg"), Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {

e.printStackTrace();
}
}
// When the response returned by REST has Http response code other than '200'
public void onFailure(int statusCode, Throwable error,
String content) {
