Re: [android-developers] Re: RuntimeException: Canvas: trying to use a recycled bitmap
I did. I changed some stuff to avoid out of memory errors --just for debug sake, can't be done in the working app-- and then commented the calls and the exception is thrown anyway. It seems like something outside my code is trying to recycle some bitmap.

Re: [android-developers] Re: RuntimeException: Canvas: trying to use a recycled bitmap
Does this happen if you don't use that Sherlock stuff? If you use it, you will probably have to do a lot of detective work to figure this out.

Re: [android-developers] Re: RuntimeException: Canvas: trying to use a recycled bitmap
I checked once again. There were a couple of recycle() that I didn't find the first time I searched --my Eclipse sometimes lacks of memory for this kind of tasks, it seems. I searched for the call among my files with another app, and find the culprit on the onPause() of one of de Fragments. Thanks!
