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
