You may hear that in mobile phone development you don’t need to worry about algorithms and data structure due to the computing power of the server side. However, as mentioned with regards to caching issues in the previous chapter, especially when your phone is offline, you should store your data locally and compute it within the phone environment. Here is the issue: your phone environment is not as powerful as your server environment. In other words, you don’t have the power of cloud computing or a data center.
