Implement an app and a background service, both of which work together as follows: Background Service: 1- It is a math engine service that runs all the time in the background. It is designed to receive MathQuestion from the app. 2- A MathQuestion includes variable number of parameters, one operator {Add,Sub,Mul,Div} and time to receive response. Time to receive response is a scheduled task managed by the background service, which only send a response (MathAnswer response) to the app based on the specified value. 3- Following the point above, there must be a pool or queue mechanism that manage and executes equations as scheduled tasks. App: 1- The app allows a user to enter a basic mathematical question. 2- The app allows a user to determine the delay time; i.e. 5 seconds, 30 seconds, and so on. 3- Upon hitting a button (calculate), the math equation will be sent to the background service to operate in scheduler as described above. 4- There must be a pane that shows operations that are pending execution. 5- There must be a pane that shows operation results received from the background service. 6- There must be an option to view location information i.e. GPS. Other Requirements: 1- Make sure to test your app and background service on Android. 2- Provide a build script to run your app on Android. Provide two profiles, one for QA and the other of Prod. 3- Provide analysis and profiling for the battery and memory leaks and usage of both app and background service. 4- Provide unit and instrumentation tests.
