2 years ago We found similar flaws in activities:
ExImportActivity
- Message stating error in input disappears and values change
- Selected options return to default
- The menu popup disappears
- Title disappears
- View properties change
MainActivity
- message fragment disappears
Note:
- Double screen rotation: It is executed twice to reach a state that should be exactly the same as the screen before if no data loss occurred.
- A data loss problem occurs when data is accidentally deleted or state variables are accidentally assigned with default or initial values.
This issue has relation with #75
When executing this sequence of actions, there is a loss of data in the activity EditorActivity
