  • 0

I have 4 activities A, B, C and D.

Activity A has a menu. One of its options opens Activity D which has a list view.
Activity A opens Activity B by a button. Activity B opens Activity C by a button.

Activity C has 4 ImageViews that I recycle them on finish.

When I do the following scenario every thing is OK:

A -> B –back to–> A –click Menu to go to D –> OK

When I do the following scenario I get this fatal exception:

A -> B -> C –back to–> B –back to–> A –click Menu to go to D –> get exception

There is no relation between Activity D and C. but why I get this exception here????

A->B->C (using buttons)

A-> D (using menu)

    I noticed I should not use same image resources for different Activities while one of them is recycling its bitmap.

    I was using same image resource (img01.png) for ImageViews in both Activity C and Activity D.

    I changed the image resource of Activity C to img02.png and problem solved.

    But I do not know its logical reason.
