Good morning, I'm a little confused how to correctly handle tasks (AsyncTask) when the screen orientates.
The documentation states that the object passed to onRetainNonConfigurationInstance should have no refererence to the destroyed activity/context. When i pass a pointer to a AsyncTask it shouldn't have such a reference. But in the AsyncTask onPostExecute() method (which is executed in the UI thread) the result of the task should be displayed in the fields of a activity. How can i display the result of a AsyncTask in a activity when i may not use anything that references to the destroyed activity? For example i can't pass my EditBox to the constructor of the AsyncTask, because it is a reference to the activity that will be destroyed, but i do want to put the result of the task in that EditBox ;-) I buzzles me. One solution comes in mind and that is to save the pointer to the task in onRetainNonConfigurationInstance() and restore it in onCreate(). Then call a method on the task class and pass a pointer to the new EditBox. But it isn't 100% save, cause while the screen is rotating (things are destroyed/created) the task might finish and cause unpredictable results. Can anybody give me advice on this subject?
