  • How are you persisting the info? What is happening exactly? – Denis Jul 31 '17 at 22:25
  • i am persisting with two void , this work only for rotate public void onSaveInstanceState(Bundle estado) { // Save the user's current game state string = String.valueOf(textoexportar.getText()); estado.putString("cuenta",string); super.onSaveInstanceState(estado); // Always call the superclass so it can save the view hierarchy state } public void onRestoreInstanceState(Bundle estado){ super.onRestoreInstanceState(estado); string = estado.getString("cuenta"); textoexportar.setText(string); } – 29get4l Jul 31 '17 at 22:35

  • That a look at this question: https://stackoverflow.com/questions/151777/saving-android-activity-state-using-save-instance-state but basically the instance state is not the right way of persisting info. If you want to store the information through multiples uses take a look at https://developer.android.com/guide/topics/data/data-storage.html#pref – Denis Jul 31 '17 at 22:47

  • denis what do you thing if i create a class and i store with propertys in there? – 29get4l Jul 31 '17 at 23:14
  • Another class still wouldnt persist. I would recommend using the SharedPreferences. I wrote an answear for this here: https://stackoverflow.com/questions/45220436/entering-app-exactly-as-it-was-left/45222321#45222321 – Denis Jul 31 '17 at 23:30
