Android Build a Weather App (2015) Hooking Up the Model to the View Setting the Weather Icon

Code not compiling after plugging in values from model

The following lines of code throw a warning during build and this causes the app to crash on startup

SimpleDateFormat formatter = new SimpleDateFormat("h:mm a"); formatter.setTimeZone(TimeZone.getTimeZone(getTimeZone()));

the warning is as follows

To get local formatting use getDateInstance(), getDateTimeInstance(), or getTimeInstance(), or use new SimpleDateFormat(String template, Locale locale) with for example Locale.

Is this a version issue? or am i doing something wrong?

Getting the same, but that is just a warning, you can safely ignore it. It should not be the cause of the crash.

I was having the same issue and found the solution in another post: https://teamtreehouse.com/forum/stormy-timezone-nullpointerexception-id-null

In the MainActivity.java class, in the method CurrentWeather(). At the end of the method where we "return new CurrentWeather();" is incorrect, and should instead be "return currentWeather;". This fixed both the crash I was having, as well as the temperature not showing properly.
