2, the currently displayed image on the screen recycle () away.
3, check there are no memory leaks (for example, some objects can not be recycled is always the case)

Personally, I think the most important thing is the second, we must promptly release the pictures do not show the percentage of memory.

Thank you ls, according to the words you say have a new problem, if I want to see the big picture, you need to click on the thumbnail to show larger picture, and if the display is not open, you need to manually slide to view obscured this part, the possibility that the question came up, how to get the big picture as similar as the mask layer covering the original activity, but also added gesture events, do cause a memory leak big? (Personal feeling is very likely caused by a memory leak)

Third, when the zoom display again after the end of the drag action to acquire, build, draw Bitmap
