Abstract: Today, as astronomical science becomes more and more popular, more and more astronomy enthusiasts are willing to walk in and understand astronomy. In order to make the astronomical enthusiasts more convenient to carry out astronomical observation activities and understand the weather dynamics in real-time, this paper completes the design and implementation of the real-time viewing and forecasting system based on Android. Based on the C/S architecture, the system uses Android Studio as the development platform to construct an integrated platform including many functions of astronomical observations such as cloud information forecasting, atmospheric viewing, and observation suitability evaluation. At the same time, the observational suitability evaluation based on the analytic hierarchy process is realized to satisfy the observation information needs of many astronomy enthusiasts and provide great convenience for their astronomical observation activities.

Key words: mobile APP development, Android, celestial phenomena forecast, astronomy, analytic hierarchy process
