creating_apps_in_kivy's Issues

There is a bug in the Chapter 3 tutorial with the weather data. Do I need to do anything to access the Internet outside the firewall in MacOS?

When running the example 2-9 for map search , it shows following error

app.root.childern

def on_config_change(self,config,section,key,value):
if config is self.config and key=="temp_type":
try:
print(self.root.children)
except :
pass

output:
[<main.CurrentWeather object at 0x0916AAB0>]

in chapter 6 example 6-11
i could not undrstand why CurrentWeather is child of WeatherRoot
in fact i think AddLocationForm should be its child

can any body explain this?

Chapter 12 Image Assets and Code Missing

The last chapter references a number of images assets:

• background.png (starfield)

• ship.zip (collection of PNGs of the ship for animation)

• enemies.atlas

• enemies-0x.png (x being from 1-3)

  Neither the code nor the images assets are there. (Unless the assumption is that the reader ought to replicate everything themselves.)

ListView has been deprecated since kivy version 1.10.0

The code examples need to be updated to implement the RecycleView widget instead of the ListView widget.

API Key

The book indicates "no need", but OpenWeatherMap needs an API key from now on.
