Thank you received: 0

THe situation:

I create Thumbnails of PDFs in multiple Asynctasks.
I present the PDFs in a Gridview inside a Scrollview.
I render only the PDFs that are currently visible( using the getView function)
That means, that i have to cancel the tasks, if a view is not visible anymore on the SCrenn (recycled or whatever)
To do this i cancel the asynctask but i check "ifCanceled()" during the operations.
If i fling through the list i am spawning new Tasks and cancel them acordingly.

Sometimes if i fling through the list i get a fatal error indicating, that the renderToBmp() function is using a fault adress (so i guess it is accessing memory that is already freed).
This only happens with directories with ca 500 files (as i have tested so far) and excessive scrolling.

I cant catch the error, because it is only one command: renderToBmp

If you need a Video or the code, let me know, i tried everything but i assume the following:

"The task is spawned and working
rendertobmp is called,
the task is canceled
Because the is no reference anymore to the task, the system gc.
the bitmap is freed and rendertoBmp is calling a fault address.
"

Do you have any idea to avoid this?

The Log is as follows:

radaee Offline Moderator Posts: 1123 Thank you received: 73	do you check is there memory leaks? for example: invoke Page.close and Document.close after rendered. i think the codes are more complex that you said here. so, may you send me some java codes? my mail: This email address is being protected from spambots.
