Performance improvement suggestion

[cataloque]

Dear developers, I am analyzing materialistic using static analysis. I found some potential slow operations of bitmap displaying inmaterialistic: "BitmapFactory.decodeResource" method was used in create Bitmap ,then it was invoked by method of .setLargeIcon();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.
