Add the features below to the following code to reach the goal

Goal: Goal: Create an app to display a weather forecast for the users current location

Features:

Create the app titled Weather Forecaster

The first screen will have a textbox for the user to enter a zip code and a button to submit

When the user enters the zip code and clicks the button, the app will navigate to the weather forecast screen.

The weather forecast screen will show the current weather for the users location in a label

Input validation for the zip code (only valid zip codes should be accepted)

Display a listview/tableview of the forecast for the next 7 days

Display High Temp, Low Temp, Humidity Pressure Sunrise and Sun Set

Display images for the forecast (eg: clouds for cloudy weather, a sun for clear weather)

Get the weather using an async task

Use the users current location from the device GPS (for this functionality, the app does not need the zip code entry in the first screen)

Database: Store location in database, and allow it to be updated via JDBC

Include screen shots of working application
