Android, Java, Picasso library, OkHttp library and Weather Underground’s API 

Weather Underground’s API provides free access to their service for developers.

For this code challenge, I create a simple weather application named “Umbrella”.

  • Hourly Weather Display

The hourly weather has two main sections. The top section is the current conditions of the entered ZIP code. If the temperature is below 60˚, use the cool color as specified by the designs. If the temperature is 60˚ or above, use the warm color as specified by the designs.

  • User Settings


– Zip Code Entry

The user should be able to enter the ZIP code as prescribed by the designs.


– Temperature Units Setting

Be able to switch between Imperial and Metric representation of the data.
