This error message is thrown when the process' memory limit has been reached.
In other words, there is no hard limit to the size of bitmap that can be constructed by the system. Most phones have a 16MByte heap-limit. Phones with larger cameras (allowing to snap pics with 5 or 8MPix) may have a 24MByte heap-limit. This means that the absolute upper limit is either 16 or 24MByte. However, the rest of your app uses memory as well. You have to subtract that from the 16 or 24MByte. In my app, i have a hard limit of 8MByte for images. I.e. if an image's data would be more than 8MByte, i set the inSampleSize to a value larger than 1. In the mean time, i'm very aggresive in cleaning up memory in the rest of my app if i'm about to load a large image (clear caches, especially ones holding bitmaps, calling System.gc() forcefully, etc).
