Sposób testowania i oczekiwane efekty

Podzczas testowania aplikacji na emulatorze przydatna może być znajomość pewnych skrtótów

• Android Emulator Shortcuts
• Android Emulator

1. Uruchamiamy aplikację
   
   
2. Na pierwszym ekranie (aktywność pierwsza) kontrolka Chronometer powinna odmierzeć czas.
   
   Naciskamy przycisk Go to Activity 2.
3. Ekran drugi (aktywność druga).
   
   Naciskamy przycisk Go to Activity 3.
4. Ekran trzeci (aktywność trzecia).
   
   Widzimy licznik wyświetlający wartość 0 w polu tekstowym typu TextView. Wartość tego licznika zmienia się przy każdej zmianie konfiguracji i zapamiętywany oraz odtwarzany jest wraz ze stanem egzemplarza aplikacji (metody onSaveInstanceState oraz onRestoreInstanceState).
5. W polu tekstowym typu EditText wpisujemy tekst kontrolny: test test test
   
   
6. Zmieniamy orientację telefonu (Ctrl+F12 w emulatorze). Tekst z pola tesktowego typu EditText został odtworzony bez naszego udziału (pamiętamy, że zmiana orientacji powoduje zmianę konfiguracji telefonu a w konsekwencji pownowne utworzenie danej aktywności).
   
   Wartość licznika została zwiększona o 1.
   
   
7. Ponownie została zmieniona orientacja (Ctrl + F11 w emulatorze). Tekst zachowany, licznik zwiększony.
   
   Naciskamy klawisz Home (Home w emulatorze)
8. Powracamy do ekranu głównego telefonu.
   
   
9. Ponownie uruchamiamy naszą aplikację (bardziej precyzyjnie: wznawiamy ją).
   
   
10. Powinniśmy zobaczyć ekran 3. Tekst zachowany, licznik zwiększony.
    
    
11. Ponownie została zmieniona orientacja (Ctrl + F12 w emulatorze). Tekst zachowany, licznik zwiększony. W tym przypadku udało się nawet przechwycić komunikat typu Toast związany z obsługą stanu egzemplarza niezwiązanego z konfiguracją (metoda onRetainNonConfigurationInstance do zapisu pewnych wartości, metoda getLastNonConfigurationInstance do odtworzenia).


Naciskamy przycisk wstecz (ESC w emulatorze).
12. Ekran drugi (aktywność druga).
    
    Naciskamy przycisk Go to Activity 3.
13. Powinniśmy zobaczyć ekran 3. zarówno tekst jak i licznik nie zostały zachowane. Przycisk wstecz powoduje zakończnie aktywności z której się wychodzi. A zatem musiała ona zostac od nowa zbudowana tak jak gdybyśmy uruchamiali ją pierwszy raz.
    
    Naciskamy przycisk wstecz (ESC w emulatorze).
14. Powinniśmy zobaczyć ekran 2.
    
    Naciskamy przycisk wstecz (ESC w emulatorze).
15. Powinniśmy zobaczyć ekran 1.
    
    
16. Na kórym kontrolka Chronometer odmierza czas. Za każdym razem jednak, gdy wyświetlamy ten ekran, jest ona zerowana.
    
    Naciskmay przycisk Finish aby zakończyć aplikację
17. 
    
    
18. Rozwijamy górne menu w celu obejrzenia powiadomień typu Notification.
    
    

Wygląd przykładowych powiadomień typu Notification zaprojektowanych przez użytkownika.

   zawierającą następujące pliki
   • AndroidManifest.xml
   • activity_main.xml
   • activity_2.xml
   • activity_3.xml
   • MainActivity.java
   • Activity2.java
   • Activity3.java
   • strings.xml
   • LogLifecycleActivity.java
   • my_notification_layout.xml
   • Do projektu należy jeszcze w katalogu res/drawable umieścić ikony wykorzystywane przez Toast, ale to można łatwo wygenerować klikając na katalogu res prawym przyciskiem myszy.
