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.

How can i direct to dashboard page if the user has not logout to the
system?

I have checked the session on the Login page .If isLoggedIn() == true then i have switched to the Dashboard page.
sessionmanagement
public boolean isLoggedIn() {
System.out.println("Pref" + pref.getBoolean(IS_LOGIN, false));
return pref.getBoolean(IS_LOGIN, false);
}
public boolean checkLogin() {
// Check login status
if (!this.isLoggedIn()) {
// user is not logged in redirect him to Login Activity
Intent i = new Intent(_context, Login.class);
// Closing all the Activities
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// Add new Flag to start new Activity
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Staring Login Activity
_context.startActivity(i);
}
// return false;
return false;
}
Login
if (session.isLoggedIn() == true) {
Intent intent = new Intent(this, Home.class);
startActivity(intent);
}
one can do with checking the session expiry time also

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 :
RegisterActivity :
public class RegisterActivity extends AppCompatActivity implements ServerRequests.Registereponse {
private EditText password, phone, email;

}
// Check for login
public boolean isUserLoggedIn() {
return pref.getBoolean(IS_USER_LOGIN, false);
}
}

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

This is my Server response:
{
"tag":"login",
"success":1,
"error":0,
"user":{
"email":"sridhar#gmail.com",
"password":"7a4fb4770d2c404b0c48abd49f4c5f6a",
"id":"118"
}
}

If you want to store only id in shared preference from you server responce, you can do it like,
JSONObject jsonObject = new JSONObject("Your response from server");
JSONObject jsonObject1 = jsonObject.getJSONObject("user");
String id = jsonObject1.getString("id");
SharedPreference sp = getApplicationContext().getSharedPreferences(
"sharedPrefName", 0); // 0 for private mode
Editor editor = sp.edit();
editor.putString("key_name",id); // key_name is the name through which you can retrieve it later.
editor.commit();
// To retrieve value from shared preference in another activity
SharedPreference sp = getApplicationContext().getSharedPreferences(
"sharedPrefName", 0); // 0 for private mode
String id = sp.getString("key_name","defaultvalue"); // key_name is the key you have used for store "id" in shared preference. and deafult value can be anything.
Default value will be returns if your shared preference dose not have any value for given key, else value stored for key is returns

Well, since you already have the id in the json_user object, just do this:
String userId = json_user.optString("id");
if(!userId.isEmpty()) {
getSharedPreferences(YOUR_PREFERENCE_NAME, MODE_PRIVATE).edit().putString(YOUR_USER_ID_KEY_NAME, userId).commit();
}
Then later to retrieve it, use:
String userId = getSharedPreferences(YOUR_PREFERENCE_NAME, MODE_PRIVATE).getString(YOUR_USER_ID_KEY_NAME, null);
if(userId != null) {
//Successfully retrieved user id
}
else {
//Id not found in preferences
}

Getting cannot convert jsonarray to json object

Hi i am developing an app which uses mysql db but when i try to get the values and display it i get the following error.
02-20 05:48:33.021: W/System.err(1723): org.json.JSONException: Value [{"3":"images\/BigBazaar.png","2":"Jayanagar 4th Block","outlet_name":"Big Bazaar","1":"Big Bazaar","0":"1","outlet_image":"images\/BigBazaar.png","outlet_location":"Jayanagar 4th Block","outlet_id":"1"}] of type org.json.JSONArray cannot be converted to JSONObject

Getting cannot convert jsonarray to json object
because your are getting JSONArray instead of JSONObject from server so just change your code by converting String to jsonArray as :
JSONArray jsonArr = new JSONArray(response); //<<< convert to jsonarray
// extract jsonObejct from JsonArray
JSONObject store = jsonArr.getJSONObject(0);
instead of
JSONObject store = new JSONObject(response);
