I have error on binding.setWeather(displayWeather); , the error is on displayWeather specifically.

setWeather(com.teamtreehouse.stormy.CurrentWeather)' in '' cannot be applied to '(teamtreehouse.com.CurrentWeather)

Hi Spencer. Is the variable type in your activity_main.xml file correct? It should be:

<data>
     <variable
         name = "weather"
         type = "com.teamtreehouse.stormy.CurrentWeather"/>
</data>

If your package name is com.teamtreehouse.stormy, that is. If it's different, adjust the type accordingly.

Every thing is the same except "teamtreehouse.stormy.CurrentWeather" is red

So your package name (you can find it at the very top of MainActivity.java or in the project tree in the left menu) is com.teamtreehouse.stormy? Not teamtreehouse.com?

My package name is teamtreehouse.com

I changed type to "teamtreehouse.com.CurrentWeather", and I have no error about binding now.

You're welcome! I'm happy to hear everything is working fine now :). However, for your future apps, remember that, by convention, a package name is like a reverse internet domain name. So if your domain name is myapp.example.com, your package name should be com.example.myapp.
