A screenshot of the application

Adding, removing and selecting locations

The application is not configured to use any default locations, but a list of preset locations are supplied. Select the text field at the bottom of the screen, start entering a place name, and suggestions for the location will be presented. You can optionally select one of the suggestions. Press the Add button to add the location to the list.

To remove a location from the list, press and hold the relevant item in the list until the Remove and Cancel buttons appear below the list. Press Remove to remove the item or Cancel to keep it.

To view a forecast for a location, tap the relevant item. If a connection to the server can be established, the location list will be hidden and the forecast will be shown. Otherwise, a "No connection" message will be displayed.

Building the application

The application is written in the Serpentine language which requires the DUCK software to be installed or on the PYTHONPATH. Additionally, you will need to have created a key and signing certificate in order to create an installable package unless you are using a separate signing process.

The current version of this application (1.0.4) has been tested to build with DUCK version 1.0.3.

The script supplied with the application can then be run in the following way, where <key.pem> and <cert.pem> are the locations of your key and certificate files:

./ <key.pem> <cert.pem> WeatherForecast.apk

You can then install the package on your Android device in the usual way.

Alternatively, if you are using a separate signing process, you can build the package without signing it in the following way:

./ WeatherForecast.apk
