Unexpected behaviours after a screen orientation change (reported by activity)

[datalossdetector]

I developed an automatic test case generation tool and it detected these problems in your app.
I would like to know if you consider them as failures and, if not, why. Thanks for your collaboration.

1. In WelcomeActivity, when I change the orientation of the device screen, the Dialog widget with "Change Log" title disappears.
   
   

2. In ListProjectActivity, when I change the orientation of the device screen, the TextView with android:id "message" disappears.
   
   

3. In EditProjectActivity, when I change the orientation of the device screen, some EditTexts inside this activity lose their values.
   
   

4. In CountOptionsActivity, when I change the orientation of the device screen, the TextEdits inside this activity lose their values.
   
   

5. In CountingActivity, when I change the orientation of the device screen, the "Title" TextView disappears.
