Application developers face many challenges while creating an application for use in nextgeneration hand-held devices like smartphones, tablets, and smartwatches. As they are very small as compared to actual computers, developers have to keep that in mind that there are limited amount of resources in these handheld devices. So, they have to create an optimized application that not only suffices the need of the user, but as well as satisfy the user with its performance as well. This research paper introduces with the problems encountered by the developer. Also, it aims to provide some reasonable approaches to optimize the applications. We have to take several applications into account as one application could not suffice the need to give us an optimal approach.
