Performance improvement suggestion

[cataloque]

Dear developers,
I am analyzing GeekNews using static analysis. I found some potential slow operations of bitmap displaying in GeekNews: "BitmapFactory.decodeByteArray" method was used in create Bitmap ,but Android documentation says" The BitmapFactory.decode* methods should not be executed on the main UI thread if the source data is read from disk or a network location (or really any source other than memory)."
for performance considerations, it is better to move these operations to worker threads (e.g., via AsyncTask).

thanks.
