Hello everyone, I have a problem sending getText from a spinner, I need the selected spinner option to go to another java activity.
this is the line 1 of the spinner that should send the information, and it is in java activity_main
editor.putString("RUTA", spnrEmployee.getText().toString().trim());
and this is the line 2 that receives the information from the previous one, and is in another activity (java activity2)
requestParams.put("username", sharedPreferences.getString("RUTA", ""));
Below I attach the activitymain
