What is happening? Query too slow? Network slow? data too big? application processing the data is too slow?

data too big

If possible do the major calculation in the server. If data is big it might be wise to do major calculation in the server side. Think about a 3 Tier application.

can i do it using data synchronization?

Why would you?
It is also very difficult for us to help you with absolutely no information about your application, the data, where it is stored, how you are retrieving it.
If the "data is too big" then don't retrieve it all all at once - think about your User.

As @CHill60 said, it is difficult for us to give you idea how to solve this problem, since we are not familiar with your requirement, architecture. You can consider few issues as solution:
1. Paging. Splitting data in smaller chunk and send next chunk when user request. Example of user request can be 'scrolling down' or 'scrolling up', also caching up data in Android device.
2. As I have suggested before do heavy processing can be done in server side.

Please take a look at the link that well describe this: Three-tier architecture - ManagementMania.com[^]
