Activity not opening after signing in

I'm currently creating an application that allows the user to login using a web api. While checking response of the API , i'm not getting any error.
{"error":0,"data":[{"id":"2","driver_name":"Test Driver","driver_lat":"","driver_long":"","driver_mobile_no":"9164618545","driver_password":"202cb962ac59075b964b07152d234b70","driver_token":"bef1032495ef4b2c891795fce1fa16c2","driver_image":"","is_active":"1","on_duty":"0","t_drivers":"0","created_at":"2017-07-04 06:38:22","last_activity_at":"2017-07-04 09:19:08"}],"msg":"Login Successfully."}
But while using the app, it does not go to the mainActivity.
This is the login class:-
public class login extends AppCompatActivity {
private Button login1;
Session session;
private ConstraintLayout mRootLayout;
boolean doubleBackToExitPressedOnce = false;
boolean status = false;
EditText mEdtEmail , mEdtPassword ;

mEdtEmail = (EditText) findViewById(R.id.phone_number);
mEdtPassword = (EditText) findViewById(R.id.password);
session = new Session(login.this);
if (session.isLoggedIn()) {
// User is already logged in. Take him to main activity
Intent intent = new Intent(login.this, MainActivity.class);
startActivity(intent);
finish();
}
// sign_in();
login1.setOnClickListener(new View.OnClickListener() {

Please Help!
Thanks!!
EDIT 1: Thanks a lot! I've gotten the solution for this. It was a really small error on my part!

Your jsonObject1.getString("msg"); don't have any msg
{"error":0,"data":[{"id":"2",.....}],"msg":"Login Successfully."}
// ` ^^^^^ part of jsonObject`
|_____________|
| first json object which has no msg key/value pair
|________________|
| jsonarray
|_______________________________________________________________|
|
JSONObject jsonObject = new JSONObject(result);
// response object
String status = jsonObject.optString("error");
// response json contains error , so far so good
..
..
JSONArray jsonarray = jsonObject.getJSONArray("data");
// get the jsonarray
JSONObject jsonObject1=jsonarray.getJSONObject(0);
// get first object
status = jsonObject1.getString("msg");
// there is no msg string in jsonObject1 hence error
so use
jsonObject.optString("msg");
Note : Apparently you are starting your MainActivity twice so remove one and from doInBackground which works on background thread so don't do this
Intent intent = new Intent("oodi_design.driver4.Activity.MainActivity");
startActivity(intent);
activity.startActivity(new Intent(activity, MainActivity.class).putExtra("driver_obj" , driver));
Start your activity from onPostExecute

Here you are getting JSONObject in response from server.
This object contains three values:
error
data
msg
error contains error code in integer format.
data contains JSONArray which contain the details of the driver.
msg contains the message in String format.
So you need to write
JSONObject jsonObject = new JSONObject(result);
int code = jsonObject.getString("error");
if (code == 0) {
JSONArray jsonarray = jsonObject.getJSONArray("data");
JSONObject data = jsonarray.getJSONObject(0);
String msg = jsonObject.getString("msg");
driver = new Driver();
...
}
and remove this from doInBackground method
Intent intent = new Intent("oodi_design.driver4.Activity.MainActivity");
startActivity(intent);
activity.startActivity(new Intent(activity, MainActivity.class).putExtra("driver_obj" , driver));
overridePendingTransition(R.anim.right_in, R.anim.left_out);
finish();
and write this code in onPostExecute method after displaying Toast
...
activity.startActivity(new Intent(activity, MainActivity.class).putExtra("driver_obj" , driver));
overridePendingTransition(R.anim.right_in, R.anim.left_out);
finish();
...
You need to declare Driver in UserLoginTask after ProgressDialog like
...
ProgressDialog progressDialog;
Driver driver;

From your attached JSONObject, its seems that JSONObject contains two string (error and msg) and one JSONArray named data.
So you have to parse this JSON data as below:
.........
..............
String result = WebService.postHttpResponse(mUserName, mPassword, activity);
JSONObject jsonObject = new JSONObject(result);
// ERROR & STATUS
String status = jsonObject.optString("error");
String msg = jsonObject.optString("msg");
// DATA
JSONArray jsonArrayData = jsonObject.getJSONArray("data");
// First DATA JSONObject
JSONObject jsonObject1 = jsonArrayData.getJSONObject(0);
........
..............
To start MainActivity, use below code in onPostExecute() :
#Override
protected void onPostExecute() {
Intent intent = new Intent(login.this, MainActivity.class);
intent.putExtra("driver_obj" , driver); // driver should be declared as global in `UserLoginTask` class.
activity.startActivity(intent);
overridePendingTransition(R.anim.right_in, R.anim.left_out);
finish();
}
Hope this will help~

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.

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

SharedPreferences to save login data

In my application a user starts the application and try to logs in , the application checks whether there is in the Shared Set < User> with the list of credentials for all users , if it does not exist create it from scratch .... Here's my question is how do I check in the shared existence of this Set < User>?

Here, have a look at my code for shared preferences. This code will save your login data.
public class MainActivity extends Activity {
SharedPreferences sharedpreferences;
TextView name;
TextView email;
public static final String mypreference = "mypref";
public static final String Name = "nameKey";
public static final String Email = "emailKey";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
name = (TextView) findViewById(R.id.etName);
email = (TextView) findViewById(R.id.etEmail);
sharedpreferences = getSharedPreferences(mypreference,
Context.MODE_PRIVATE);
if (sharedpreferences.contains(Name)) {
name.setText(sharedpreferences.getString(Name, ""));
}
if (sharedpreferences.contains(Email)) {
email.setText(sharedpreferences.getString(Email, ""));
}
}
public void Save(View view) {
String n = name.getText().toString();
String e = email.getText().toString();
Editor editor = sharedpreferences.edit();
editor.putString(Name, n);
editor.putString(Email, e);
editor.commit();
}
public void clear(View view) {
name = (TextView) findViewById(R.id.etName);
email = (TextView) findViewById(R.id.etEmail);
name.setText("");
email.setText("");
}
public void Get(View view) {
name = (TextView) findViewById(R.id.etName);
email = (TextView) findViewById(R.id.etEmail);
sharedpreferences = getSharedPreferences(mypreference,
Context.MODE_PRIVATE);
if (sharedpreferences.contains(Name)) {
name.setText(sharedpreferences.getString(Name, ""));
}
if (sharedpreferences.contains(Email)) {
email.setText(sharedpreferences.getString(Email, ""));
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

Here is simple login code we can store data by putString method of Editor class
SharedPreferences.Editor editor = sp.edit();
editor.putString("User", c.getString(c.getColumnIndex("Name")).toString());
editor.commit();

If your login api response is like below
{
"status": true,
"message": "Login Success",
"data": {
"user_id": "1",
"first_name": "Ketan",
"last_name": "Ramani",
"username": "ketanramani"
}
}
Then you can save all login response by dynamically using below code
SharedPreferences preferences = getApplicationContext().getSharedPreferences("LoginPref", MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(dataObject.toString());
Iterator<String> iterator = jsonObject.keys();
while (iterator.hasNext()) {
String key = iterator.next();
editor.putString(key, jsonObject.optString(key)).apply();
}
} catch (JSONException e) {
e.printStackTrace();
}
Your data will save in sharedpreferences like below
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<string name="user_id">1</string>
<string name="first_name">Ketan</string>
<string name="last_name">Ramani</string>
<string name="username">ketanramani</string>
</map>

Note: I wrote this code when for another url, but now the url has been changed and the old one was not in use. But the JSON data are same like previous but I don't know why its not working.

how to save JSONObject reponse using Shared Preferences in App

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
}
