Question

I have tried following code in which i am trying to create session of user until it logout the application. The problem is i am trying to send information of user to the page profile.java. I tried using intent extras but it failed. Any suggestions please.

login.java

public class login extends AppCompatActivity {
    private FunTubeOperations FunTubeDBOperations;
    private DatabaseWrapper db;
    private SessionManager session;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.login);
        final AlertDialog ad = new AlertDialog.Builder(this).create();
        Button login = (Button) findViewById(R.id.login);
        Button reg = (Button) findViewById(R.id.reg);
        FunTubeDBOperations = new FunTubeOperations(this);
        FunTubeDBOperations.open();
       // SQLite database handler
        db = new DatabaseWrapper(getApplicationContext());

        // Session manager
       session = new SessionManager(getApplicationContext());

        // Check if user is already logged in or not
        if (session.isLoggedIn()) {


            // User is already logged in. Take him to main activity
            Intent intent = new Intent(login.this, profile.class);
            //intent.putExtra("name", user);
            startActivity(intent);
            finish();
        }
       try {
          login.setOnClickListener(new View.OnClickListener() {
           public void onClick(View arg0) {
             EditText email = (EditText) findViewById(R.id.email);
             EditText password = (EditText) findViewById(R.id.password);
              if (email != null && password !=null) {
               String em=email.getText().toString();
               String pwd=password.getText().toString();
               String user=  FunTubeDBOperations.loginUsers(em, pwd);
                  if(user!=null)
                    {
                   session.setLogin(true);
                   Intent intent = new Intent(login.this, profile.class);
                   intent.putExtra("name", user);
                   startActivity(intent);
                   finish();
                   }}
            });

        } catch (Exception er) {
            ad.setMessage(er.toString());
        }
    }
}

your code if perfect in profile.java which getting extra data? — Sameer Donga, Dec 22 '15 at 17:55
@SameerDonga its ` welcometxt.setText("Welcome " + extras.getString("name").toUpperCase())` — tabia, Dec 22 '15 at 17:58
are you going http://stackoverflow.com/a/4233898/3713967 this way? — Sameer Donga, Dec 22 '15 at 18:03
@SameerDonga i have done this when i login and redirect to profile activity. It works but now i want to do this when session is set true. — tabia, Dec 22 '15 at 19:00
Do you still want to do this using `putExtra`? If so posting your `profile` class might help. — Peter Gordon, Dec 22 '15 at 19:51
(unrelated side-note, you have a typo in the DatabaseWrapper constant `FUNTUBE_QUOTE = "_qoute"`) — Peter Gordon, Dec 22 '15 at 19:54
@pgmann will it help me passing user information to profile.java — tabia, Dec 22 '15 at 21:44

It is possible using your way but i have another things that can also help you.

do one thing create public static variable and set your data in this variable. after that from your profile class use this variable like global variable.

like Way no 1.

login.java

public static String UserName = null;
// set user name after login in above variable
UserName = "tempUser";

// using intent go to profile page without passing any extra data
// before call intent check that UserName should not be null;

profile.java

// get user name
TextView username;
username.setText(Login.UserName);

way no.2

Store data in preference.. set preference data form login and get preference data from profile.

`Login.UserName` should be `login.UserName` (although the class should really be renamed to `Login` to match standards). Apart from that I'd recommend this way. The preference way (2) may be slightly more robust than way 1, and you may find you want to store the username in preferences anyway to prevent the user from having to log in each time. — Peter Gordon, Dec 23 '15 at 10:38
