First of all thank you very much everyone for your help. I continue with a problem. I use Runtime.getRuntime().freeMemory() for obtain the free memory and compare it with the real Bitmap memory. Sometimes I get a free memory less than that occupied by the image. However, if I remove the restriction on the size of the image, I can work with it without any problem. Am I using an incorrect function to get the free memory?. Should I use another function?
Thank you very much in advance.
