COMPOLICE ST™ Application Computer Science Questions


COMPOLICE ST™ is your personal mobile app community policing app that is intended to aid police services in the US in gathering data about various hot spots within each territory.

The app should be able to support picture/video upload; for each upload, there should be appropriate data and metadata. 
The app should allow the user to report a community disturbance.  
The app should be able to list each police station in the country you are in.

The app should provide at least four (4) information pages, such as a page containing a list of emergency numbers etc.
