,每的ImageView
(被称为 SomeAdapter#getView( )
)。任务本身做了很多事情,其中之一是调用 DiskLruCache
,但是当SD卡被卸载,而任务依然运行的应用程序崩溃。
I have a class which is used to get media file thumbs. This Loader like class starts an AsyncTask
for every ImageView
(is called in SomeAdapter#getView()
). The task itself does a lot of things, and one of them is calling DiskLruCache
, but when the SD card is unmounted, while the tasks are still running the application crashes.

I know how to register if the card state is changed.
