In my android application i u开发者_JAVA技巧sed 3 imageView objects. for performing the touch action i set the touch listener and implement the opereations. when running the application it works for some touches of the imageview, after that the application hangs and finally i saw an error "keydispatching timeout". Then i implement asyncTask for the operations of imageView touch. but the problem still arises. Anybody please help me to solve this problem

Apparently you have some long or even blocking operation in your QueueAdderZoom class's constructor or execute.
