NullPointer #10

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When binding to multiple ImageViews within a BaseAdapter, ImageLoader will 
throw a NullPointerException if another activity is loaded over the current one 
when async bind requests are still pending.  

What steps will reproduce the problem?
1. Request to bind a number of remote images to ImageViews within a BaseAdapter
2. Load another activity on top before all requested images have finished 
loading
3. Boom goes the dynamite

What is the expected output? What do you see instead?
A different activity loaded on top of the previous one, which was utilizing 
ImageLoader on a ListView.  Instead, get a NullPointer of app-death.  

What version of the product are you using? On what operating system?
SDK Tools 11, targeting 1.6.  Not sure which version of ImageLoader, but it was 
the most recent version no earlier than a month ago.  

Please provide any additional information below.

Are you using ImageLoader#bind(ImageView, String, Callback) or 
ImageLoader#bind(BaseAdapter, ImageView, String)?
