Hi,

I have created an application of contacts synchronization. when i run it on device it hangs my device while synchronizing then i am not able to open another application, I am also doing auto synchonization with in a perticular period of time.

I want that synchronization should be perform without hang to device and if i get any interrupt i.e. any call while syncing then it should pause for that moment and continue at call end. How can i do this ?

Not much here to go on, but my guess is that you are performing this synchronization work in the UI event thread, which will hang the UI for the entire device until it is finished.

This type of work should be done in a worker thread, which runs in the background.
