Onetime login is not working and second time also showing LoginActivity in android

Hi in the below code I was implemented ontime login feature but it is not working with below code.If login is successful then it will redirecting to MainActivity.Next time want to skip login page directly it should show main activity.
SplashActivity.java:
final boolean needLogin = getIntent().getBooleanExtra("need login extra", true);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// This method will be executed once the timer is over
if(!needLogin) {
Intent i = new Intent(SplashActivity.this, MainActivity.class);
startActivity(i);
finish();
}else {
Intent i = new Intent(SplashActivity.this, LoginActivity.class);
startActivity(i);
finish();
}
}
},
Once the login is successfull it will redirect to MAninactivity.java.Entire app I am using session.
LoginActivity.java:
if (response.isSuccessful()) {
Log.e("response", new Gson().toJson(response.body()));
LoginAndFetchModules loginAndFetchModules = response.body();
String success = loginAndFetchModules.getSuccess();
if (success.equals("true")) {
Results results = loginAndFetchModules.getResult();
//parse login details
GetLoginListDetails loginDetails = results.getLogin();
String userId = loginDetails.getUserid();
String sessionId = loginDetails.getSession();
String firstname = loginDetails.getFirst_name();
String lastname = loginDetails.getLast_name();
String mobile = loginDetails.getMobile();
String role = loginDetails.getRole();
String reportto = loginDetails.getReportto();
//parse modules
ArrayList<LoginListForModules> modules = results.getModules();
//parse module information
for (LoginListForModules module : modules) {
module_id = module.getId();
String name = module.getName();
String isEntity = module.getIsEntity();
String label = module.getLabel();
String singular = module.getSingular();
}
if (username.equals(username1.getText().toString()) && password.equals(password1.getText().toString())) {
// fetchUserJSON(sessionId,username);
Toast.makeText(getApplicationContext(), "Login Successfully", Toast.LENGTH_LONG).show();
i = new Intent(LoginActivity.this, MainActivity.class);
// loader.setVisibility(View.GONE);
progressDialog.dismiss();
// llProgressBar.setVisibility(View.GONE);
i.putExtra("sessionId", sessionId);
i.putExtra("module_id", module_id);
i.putExtra("username", username);
i.putExtra("firstname", firstname);
i.putExtra("lastname", lastname);
i.putExtra("mobile", mobile);
i.putExtra("role", role);
i.putExtra("reportto", reportto);
startActivity(i);
finish();
} else {
Toast.makeText(getApplicationContext(), "Invalid Username and Password", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(), "Invalid Username and Password", Toast.LENGTH_LONG).show();
}
}

You can use SharedPreferences.
A SharedPreferences object points to a file containing key-value
pairs and provides simple methods to read and write them.
DEMO CODE
public class SharedPreferenceClass
{
SharedPreferences pref;
SharedPreferences.Editor editor;
Context _context;
int PRIVATE_MODE = 0;
private static final String PREF_NAME = "Test";
public static final String KEY_SET_LOGIN_STATUS= "KEY_SET_LOGIN_STATUS";
public SharedPreferenceClass(Context context){
this._context = context;
pref = _context.getSharedPreferences(PREF_NAME, 0);
editor = pref.edit();
}
public void setLoginStatus(String status)
{
editor.remove(KEY_SET_LOGIN_STATUS);
editor.putString(KEY_SET_LOGIN_STATUS, status);
editor.commit();
}
public String getLoginStatus()
{
String status= pref.getString(KEY_SET_LOGIN_STATUS, "");
return status;
}
}
Now you can store login status ( setLoginStatus("Login")) when ever login success And check your login status getLoginStatus(). If return "Login" then return to your desire activity.

unable to set a session

I am very new in android.In my app I make a login page.I use Shared Preferences for session.it works fine but a problem when i close my app and again open then login page comes.I want when user press logout button only that time login page will come.
this is my SharedPreferences class
public class SharedPrefManager {
//the constants
private static final String SHARED_PREF_NAME = "dreamzsharedpref";
private static final String KEY_USERNAME = "keyusername";
private static final String KEY_PHONE = "keyphone";
private static final String KEY_ID = "keyid";
private static SharedPrefManager mInstance;
private static Context mCtx;
private SharedPrefManager(Context context) {
mCtx = context;
}
public static synchronized SharedPrefManager getInstance(Context context) {
if (mInstance == null) {
mInstance = new SharedPrefManager(context);
}
return mInstance;
}
//method to let the user login
//this method will store the user data in shared preferences
public void userLogin(User user) {
SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putInt(KEY_ID, user.getUserid());
editor.putString(KEY_PHONE, user.getUserphno());
editor.putString(KEY_USERNAME, user.getUsername());
editor.apply();
}
//this method will checker whether user is already logged in or not
public boolean isLoggedIn() {
SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
return sharedPreferences.getString(KEY_PHONE, null) != null;
}
//this method will give the logged in user
public User getUser() {
SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
return new User(
sharedPreferences.getString(KEY_USERNAME, null),
sharedPreferences.getString(KEY_PHONE, null),
sharedPreferences.getInt(KEY_ID, -1)
);
}
//this method will logout the user
public void logout() {
SharedPreferences sharedPreferences = mCtx.getSharedPreferences(SHARED_PREF_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.clear();
editor.apply();
mCtx.startActivity(new Intent(mCtx, LoginActivity.class));
}
}
this is my login method in login class
private void userLogin() {
//first getting the values
final String username = UsernameEt.getText().toString();
final String password = PasswordEt.getText().toString();
//validating inputs
if (TextUtils.isEmpty(username)) {
UsernameEt.setError("Please enter your username");
UsernameEt.requestFocus();
return;
}
if (TextUtils.isEmpty(password)) {
PasswordEt.setError("Please enter your password");
PasswordEt.requestFocus();
return;
}
//if everything is fine
class UserLogin extends AsyncTask<Void, Void, String>{
#Override
protected void onPreExecute() {
super.onPreExecute();
progressBar.setVisibility(View.VISIBLE);
}
#Override
protected String doInBackground(Void... voids) {
//creating request handler object
RequestHandler requestHandler = new RequestHandler();
//creating request parameters
HashMap<String, String> params = new HashMap<>();
params.put("vuserphno", username);
params.put("votp", password);
//returing the response
return requestHandler.sendPostRequest(URLs.URL_LOGIN, params);//this URLs is a class where URL_LOGIN is login url
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
progressBar.setVisibility(View.GONE);
try {
JSONObject obj = new JSONObject(s);
JSONArray array = obj.getJSONArray("user");
for (int i = 0; i < array.length(); i++) {
//getting the user from the response
JSONObject userJson = array.getJSONObject(i);
//creating a new user object
User user = new User(
userJson.getString("username"),
userJson.getString("userphno"),
userJson.getInt("userid")
);
//storing the user in shared preferences
SharedPrefManager.getInstance(getApplicationContext()).userLogin(user);
}
//starting the profile activity
finish();
startActivity(new Intent(getApplicationContext(), MainActivity.class));
} catch (JSONException e) {
e.printStackTrace();
}
}
}
UserLogin ul = new UserLogin();
ul.execute();
}
please tell me where is the problem and how I can solve this problem.
Thanks.

In your LoginActivity, check for login state and change activity, finish itself so it's clear from the back stack.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
if (SharedPrefManager.getInstance().isLoggedIn(this)) {
startActivity(this, MainActivity.class);
finish();
return;
}
// ...
}

Here I am not able to get user_id using shared preference. Please help me how to get it.

In onPostExecute try this you will get User ID
try {
String userid;
JSONObject ob = new JSONObject(jsonstring);
JSONArray arr = ob.getJSONArray("VerifiedMember");
for (int i = 0; i < arr.length(); i++) {
JSONObject obj = arr.getJSONObject(i);
userid=obj.getString("user_id");
}
} catch (Exception e) {
}

You can use this pojo generator
http://www.jsonschema2pojo.org/
For parsing you can use google's gson library or jackson parser is also good.

I want to store Register and Login information in shared preferences in android

I know there are n number of examples in android for shared preferences but I want to Register and store the info in shared preferences and in database using JSON. And then fetch data from JSON and Login with those credentials. If user is already logged in open Main Activity,else go to Splash screen and then open Login Activity. Please go through my detailed code :

}

At the time of login successfull put this code:
prefs = getSharedPreferences("logindetail", 0);
SharedPreferences.Editor edit = prefs.edit();
edit.putString("userLoginStatus", "yes");
edit.commit();
At the time of logout use this:
prefs = getSharedPreferences("logindetail", 0);
SharedPreferences.Editor edit = prefs.edit();
edit.clear();
edit.commit();
And at the time of checking if user is login or not use below code:
Loginprefs = getApplicationContext().getSharedPreferences("logindetail", 0);
userLoginStatus = Loginprefs.getString("userLoginStatus", null);
if(userLoginStatus.tostring().equals("yes")){
//the user is login
}else{
//user is logout
}
Hope this helps you

HashMap save and get shared preference

I have a project and i want to save every variables that are available to the user online to the shared preference. It is their string values user_id, Fname, Lname, and their int values "lexile", "user_id".I have been following a tutorial online so far so good but it only provides saving two variables so I improvise. I didnt get any error when running but when actually using the application I cant seem to login and open the second activity maybe because of my hashmaping.
Here is the code below
this is the part of the login that is related
Response.Listener<String> responseListener = new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//SUBUKAN NA ISINGIT DINE ANG PAGCHECK SA INTERNET SERCVICE
try {
JSONObject jsonResponse = new JSONObject(response);
boolean success = jsonResponse.getBoolean("success");
//OPENS THE NEW ACTIVITY
if (success) {
String Fname = jsonResponse.getString("Fname");
String Lname = jsonResponse.getString("Lname");
int lexile = jsonResponse.getInt("lexile");
int user_id = jsonResponse.getInt("user_id");
// String username = jsonResponse.getString("username");
// int user_id = jsonResponse.getInt("user_id");
Intent intent = new Intent(Login.this, User_nav.class);
intent.putExtra("Lname", Lname);
intent.putExtra("Fname", Fname);
intent.putExtra("lexile", lexile);
intent.putExtra("user_id", user_id);
// intent.putExtra("username",username);
//intent.putExtra("user_id", user_id);
//THIS IS THE PART OF THE SESSION MANAGER
session.createLoginSession(Lname, Fname, lexile, user_id);
Login.this.startActivity(intent);
progress.dismiss();
}
This is the second activity, the codes that are related
SessionManager session;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user);
session = new SessionManager(getApplicationContext());
Toast.makeText(getApplicationContext(), "User Login Status: " + session.isLoggedIn(),Toast.LENGTH_LONG).show();
session.checkLogin();
HashMap<String, String> user = session.getUserDetails();
String Lname = user.get(SessionManager.KEY_FNAME);
String Fname = user.get(SessionManager.KEY_LNAME);
HashMap<String, Integer> user_int = session.getUserLexileNID();
Integer lexile = user_int.get(SessionManager.KEY_LEXILE);
Integer user_id = user_int.get(SessionManager.KEY_USER_ID);
TextView Name = (TextView) header.findViewById(R.id.Name);
TextView displayLexile = (TextView) header.findViewById(R.id.lexile);
Name.setText(Html.fromHtml(Lname+", " +Fname));
displayLexile.setText("Lexile Level: "+lexile + "" +user_id);
This is the SessionManager that holds all of those codes for session making.
