Login authentication with post method android and Get the other APIs collection

I am very new in android developing. In my app I have a login page, where I want to implement authentication functionality by POST method. I have a root address through which I have to login. I am giving a sample url, because it is confidential. "test.sample.com". my Protol address is https. then I need to combine "/login" at first. Just after authenticating with this login. I have more apis like "/api/users", "api/image". I can only access to this api if I authenticate with the login functinality. How can I do that. So far I have created a login page, but at this moment I have not implemented any POST method here.
public class LoginPage extends AppCompatActivity{
private UserLoginTask mAuthTask = null;
private static final String TAG = "LoginActivity";
private AutoCompleteTextView userEmail;
private EditText userPassword;
private TextView forgotPassword;
private Button login;
#Override

setContentView(R.layout.activity_login);
//Set up the login form
userEmail=(AutoCompleteTextView) findViewById(R.id.email);
userPassword=(EditText)findViewById(R.id.password);
forgotPassword=(TextView)findViewById(R.id.forgot_password);
forgotPassword.setOnClickListener(new View.OnClickListener() {
#Override

Toast.makeText(getBaseContext(),"Redirect to forgot password link", Toast.LENGTH_SHORT).show();
}
});
userPassword.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) {
if (id == R.id.password || id == EditorInfo.IME_NULL) {
attemptLogin();
return true;
}
return false;
}
});
login=(Button)findViewById(R.id.btn_login);
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
attemptLogin();
}
});
}
/**

*/

// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(LoginActivity.this);
StringRequest strReq = new StringRequest(Request.Method.POST,
"https://app.com/login", new Response.Listener<String>() {
#Override
public void onResponse(String response) {

// TODO: exit the application
}
} catch (InterruptedException e) {

return result;
}
}

Here use this:
First to check whether internet is available or not.
public boolean isReachable(String address, int port, int timeoutMs) {
try {
Socket sock = new Socket();
SocketAddress sockaddr = new InetSocketAddress(address, port);
sock.connect(sockaddr, timeoutMs); // this will block no more than timeoutMs
sock.close();
return true;
} catch (IOException e) { return false; }
}
then use volley library to hit the request:
public boolean authenticateUsingServer(final String mEmail, final String mPassword){
try {
if(isReachable("8.8.8.8", 53, 1000)){
Log.e(TAG,"Authenticate using remote server");
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(LoginActivity.this);
StringRequest strReq = new StringRequest(Request.Method.POST,
URL_LOGIN, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.e(TAG, "Login Response: " + response);
//parse your response here
result = true;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Login Error: " + error.getMessage());
Toast.makeText(getApplicationContext(),
error.getMessage(), Toast.LENGTH_LONG).show();
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Log.e(TAG,"Inside getParams");
// Posting parameters to login url
Map<String, String> params = new HashMap<>();
params.put("email", mEmail);
params.put("password", mPassword);
return params;
}
};
// Adding request to request queue
queue.add(strReq);
Thread.sleep(2000);
}
else{
Log.e(TAG,"Internet connection is required.");
/*Toast.makeText(LoginActivity.this,"Internet connectivity is required",
Toast.LENGTH_LONG).show();*/
result = false;
// TODO: exit the application
}
} catch (InterruptedException e) {
return false;
}
return result;
}
then call it like this from Async task:
#Override
protected Boolean doInBackground(Void... params) {
// TODO: attempt authentication against a network service.
authenticateUsingServer(mEmail,mPassword);
// TODO: register the new account here.
return true;
}

Replace your LoginTask with following Code :
public class UserLoginTask extends AsyncTask<Void, Void, Boolean> {
private final String mEmail;
private final String mPassword;
Activity instance ;
UserLoginTask(String email, String password , Activity instance) {
mEmail = email;
mPassword = password;
this.instance = instance ;
}
#Override
protected Boolean doInBackground(Void... params) {
// TODO: attempt authentication against a network service.
JSONObject request = new JSONObject();
request.put("email",mEmail );
request.put("pass",mPassword );
String result = connectWithServer(instance , request);
if(!TextUtils.isEmpty(result)){
return true;
}else{
return false;
}
}
#Override
protected void onPostExecute(final Boolean success) {
mAuthTask = null;
showProgress(true);
if (success) {
finish();
Intent loginIntent = new Intent(LoginPage.this, MainActivity.class);
startActivity(loginIntent);
} else {
userEmail.setError(getString(R.string.error_incorrect_password));
userPassword.requestFocus();
}
}
#Override
protected void onCancelled() {
mAuthTask = null;
showProgress(false);
}
}
Add connectWithServer() method in your Actvity class :
public static String connectWithServer(Activity ctx , JSONObject request) {
String result ="";
try {
//Connect
HttpURLConnection urlConnection = (HttpURLConnection) ((new URL(YOUR_SERVICE_URL)).openConnection());
urlConnection.setDoOutput(true);
urlConnection.setRequestProperty("Content-Type", "application/json");
urlConnection.setRequestProperty("Accept", "application/json");
urlConnection.setRequestMethod("POST");
urlConnection.connect();
urlConnection.setConnectTimeout(100000);
//Write
OutputStream outputStream = urlConnection.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "UTF-8"));
writer.write(request.toString());
writer.close();
outputStream.close();
//Read
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "UTF-8"));
String line = null;
StringBuilder sb = new StringBuilder();
while ((line = bufferedReader.readLine()) != null) {
sb.append(line);
}
bufferedReader.close();
result = sb.toString();
} catch (UnsupportedEncodingException e){
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}catch (JSONException e){
e.printStackTrace();
}
return result;
}

I just used the second code to test the trasaction. But i have to use the first posted code because i have to post the ORDERID and CALLBACKURL from android application to server . Any help would be appreciable.

**Here is the solution for all :**
Be sure to send equal number of parameters to your server (For checksum generator) And then to paytm server for payment.
**For example:**
If you are sending 6 params for checksum generator, then send these 6 same parameters including Checksum to Paytm...
It will resolve your problem.
**CODE EXAMPLE :**
**Generate checksum.php**
$paramList = array();
$paramList["MID"] = 'Provided by Paytm'; //Provided by Paytm
$paramList["ORDER_ID"] = 'hIquwhzvzTG7gvT'; //unique OrderId for every request
$paramList["CUST_ID"] = 'CUST0001453'; // unique customer identifier
$paramList["INDUSTRY_TYPE_ID"] = 'Retail'; //Provided by Paytm
$paramList["CHANNEL_ID"] = 'WAP'; //Provided by Paytm
$paramList["TXN_AMOUNT"] = '10.00'; // transaction amount
$paramList["WEBSITE"] = 'APP_STAGING';//Provided by Paytm
$paramList["CALLBACK_URL"] = 'https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp';
**Android Activity.java**
paramMap.put("MID" , "#########");
paramMap.put( "ORDER_ID" , "hIquwhzvzTG7gvT");
paramMap.put( "CUST_ID" , "CUST0001453");
paramMap.put( "CHANNEL_ID" , "WAP");
paramMap.put( "TXN_AMOUNT" , "10.00");
paramMap.put( "WEBSITE" , "APP_STAGING");
paramMap.put( "CALLBACK_URL" , "https://pguat.paytm.com/paytmchecksum/paytmCallback.jsp");
paramMap.put( "CHECKSUMHASH" , "dR5OtEkuNkgamHTZDCHmF+CF3j9RdG1520mlHEb85oSZP1CaxVUsRY2sYric90HLm/vElaPZKoQ7b5/SyFpi3oBWXf2BQNy+r6iiBwg4AH4=");
paramMap.put("INDUSTRY_TYPE_ID" , "Retail");
**NOTE : Please keep in mind to send paytm server exact parameters plus one checksum.....**

I intend to fire another asyntask which will then save the data fetched by this asyntask into the database.

Make these changes, it will work -
private class FetchOperation extends AsyncTask<Void, Void, String>
change to - private class FetchOperation extends AsyncTask<Void, String, String> , because, you are trying to return String.
response = EntityUtils.toString(httpEntity);
change to - response = EntityUtils.toString(httpEntity).toString();
at the next line of this you have actually done it.
At the very end of doInBackground method where return null;
change to - return response;
4.No need to call super in onPostExecute()
5.Inside onPostExecute() check jsonStr is null or not and do whatever you want to do if null and if contains json data.

Your JSONObject does not contain a JSONString "email", so it is falling over at line
String email = jsonObj.getString("email");
and going straight to catch block.

Getting bad request 400 error using asmack in android

I am trying to register a new user using my XMPP client using asmack library in Android on ejabberd server. The problem is that I am getting following error & the user is not being created on the server:
bad-request(400)
at org.jivesoftware.smack.AccountManager.createAccount(AccountManager.java:243)
at in.ui.MainActivity$1$1$1.run(MainActivity.java:316)
at java.lang.Thread.run(Thread.java:841)
Following is the code:
_xmppUsername = XMPPConfig.getStringUserInfoValue (XMPPConfig.XMPP_CLIENT_ID);
_xmppPassword = XMPPConfig.getStringUserInfoValue (XMPPConfig.XMPP_CLIENT_PASSWORD);
_xmppHost = XMPPConfig.getStringUserInfoValue (XMPPConfig.XMPP_HOST);
try {
_xmppPortNo = Integer.parseInt (XMPPConfig.getStringUserInfoValue (XMPPConfig.XMPP_PORT));
} catch (Exception e) {
e.printStackTrace ();
Log.e (TAG, e.getMessage ());
}
_xmppServiceName = XMPPConfig.getStringUserInfoValue (XMPPConfig.XMPP_SERVICE_NAME);
ConnectionConfiguration conConfig = new ConnectionConfiguration (_xmppHost, _xmppPortNo, _xmppServiceName);
_xmppConnection = new XMPPConnection (conConfig);
if (!_xmppConnection.isAuthenticated ()) {
login ();
}
/*
* If connection has not been established or had been established &
* broken again then login
*/
#Override
public void onShow (final DialogInterface dialog) {
Button positiveButton = _dlgRegistration.getButton (DialogInterface.BUTTON_POSITIVE);
positiveButton.setOnClickListener (new View.OnClickListener () {
#Override
public void onClick (View v) {
// Creating registration thread
new Thread (new Runnable () {
#Override
public void run () {
String clientID = null;
String password = null;
clientID = "user" + XMPP_SERVICE_NAME;
try {
// Getting hash password from UUID
password = "password";
Log.i (TAG, clientID + password);
} catch (NoSuchAlgorithmException e1) {
e1.printStackTrace ();
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace ();
}
}
AccountManager manager = _xmppConnection.getAccountManager ();
try {
// Creating account on the server
manager.createAccount (clientID, password, attr);
}
} catch (XMPPException e) {
e.printStackTrace ();
}
}
}).start ();
}
});

The problem was this line clientID = "user" + XMPP_SERVICE_NAME; where I shouldn't have been appending Domain or Service Name after "user".

HTTP post 400 bad request

When I try to use my restTemplate.postForEntity I get a 404 bad request
What is my fault?
Code:
Servercaller:
public ServerError login(String username, String password) {
User user = new User();
user.setUsername(username);
user.setPassword(password);
try {
String URL = "http://"+ipAddress+"/ProjectTeamF-1.0/service/login.json";
Object[] params = new Object[]{URL,user};
new login().execute(params);
} catch (ResourceAccessException rae) {
receivedUser = null;
return ServerError.ServerNotFound;
} catch (HttpServerErrorException hsee) {
receivedUser = null;
return ServerError.WrongData;
} catch(RestClientException rce){
receivedUser = null;
return ServerError.WrongData;
} catch (Exception e) {
System.out.println("error " + e);
receivedUser = null;
return ServerError.OtherError;
}
return ServerError.NoError;
}
AsyncTask:
public class login extends AsyncTask<Object[], Void, Void> {
public ServerCaller sc = ServerCaller.getInstance();
public User body;
#Override
protected Void doInBackground(Object[]... params) {
String message = "";
try {
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<User> _entity = new HttpEntity<User>((User)params[0][1], requestHeaders);
RestTemplate templ = new RestTemplate();
templ.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
templ.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
ResponseEntity<User> _response = templ.postForEntity(params[0][0].toString(), _entity, User.class); //null here in order there wasn't http converter errors because response type String and [text/html] for JSON are not compatible;
body = _response.getBody();
return null;
} catch (Exception e) {
message = e.getMessage();
return null;
}
}
#Override
protected void onPostExecute(Void aVoid) {
super.onPostExecute(aVoid);
sc.setReceivedUser(body);
}
}
When I debug the program crashes at templ.postForEntity(). The error tells me that this is a 400 - bad request.
Thanks!
