Recently our two applications on Android Market kept reporting error “java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap…”. If you look at the stack trace, there is no trace of our code. Below is one of the stack trace:

After searching around the Internet, I found some clues. It has something to do with the call of bitmap.recycle(). Some people suggest to remove all the calls to bitmap.recycle() and let the garbage collector to do the job. So I tried this solution and updated the Packing List application. I will give it a day or two to see if it settles the issue.
