Android Java sharedPreferences logic issue -


android java sharedpreferences logic issue

i have app has sign in , sign out in it.

i want, when user first downloads app, sign out. when signs in using button, sharedpreference value saves. next time opens app, automatically sign him in. lets signs out closes app, when opens it, sign him out. thats how goes apps.

what did, @ first of activity added this

    sharedpreferences siggnedin = getsharedpreferences("yesorno", activity.mode_private);     sharedpreferences.editor editor = siggnedin.edit();     editor.putboolean("siggnedin?", false);     editor.commit();

then when user clicks button signs out

                            sharedpreferences siggnedin = getsharedpreferences("yesorno", activity.mode_private);                             sharedpreferences.editor editor = siggnedin.edit();                             editor.putboolean("siggnedin?", false);                             editor.commit();

and if clicks sign in

                                 sharedpreferences siggnedin = getsharedpreferences("yesorno", activity.mode_private);                                  sharedpreferences.editor editor = siggnedin.edit();                                  editor.putboolean("siggnedin?", true);                                  editor.commit();

and @ last, if have method updates every second.

so in it, add

            sharedpreferences siggnedin = getsharedpreferences("yesorno", activity.mode_private);             boolean myintvalue = siggnedin.getboolean("siggnedin?", false);              if(myintvalue){                 signhimin();             }

that doesn't work.

keep things simple

check status

sharedpreferences pref = getsharedpreferences("usersession", activity.mode_private); boolean isloggedin = pref.getboolean("isloggedin", false);

sign in

sharedpreferences pref = getsharedpreferences("usersession", activity.mode_private); sharedpreferences.editor editor = pref.edit(); editor.putboolean("isloggedin", true); editor.commit();

sign out

sharedpreferences pref = getsharedpreferences("usersession", activity.mode_private); sharedpreferences.editor editor = pref.edit(); editor.putboolean("isloggedin", false); editor.commit();

simple logic

protected boolean isusersignedin(){     boolean isloggedin = false;      sharedpreferences pref = getsharedpreferences("usersession", activity.mode_private);     isloggedin = pref.getboolean("isloggedin", false);//false default      return isloggedin; }

usage

if(!isusersignedin()){    signhimin(); }
