}

This is the log

How can I resolve this?

The reason is java.lang.OutOfMemoryError meaning your computations eat too much RAM.

However without knowing what you do it is difficult to say what exactly causes the error. Probably you create too many images/bitmaps.

Here is the info on how much RAM is availiable for your app: https://stackoverflow.com/a/9940415/247013

Ideas for investigation:

make use of Bitmap.recycle() - call it whenever you don't need a processed Bitmap
try not to store the images in RAM, persisting them to files instead
looks like you're trying to pre-create an image for any possible effect in advance - consider re-architechting - do one effect only when user explicitly asks for it (on demand).

Thank you i figure out the problem which cause by the size of bitmap images — Mazen Kamel, Apr 08 '13 at 16:15
