iOS Development with Swift Techdegree Student 5,114 PointsAndroid Studio 3.1.3 on Windows doesn't generate ActivityHourlyForecastBinding so I can't import
I tried (almost) everything to import com.URL.stormy.databinding.ActivityHourlyForecastBinding but nothing works. I rebuilt, cleaned the project. I restarted Android Studio. Changed the name of the .xml file. I done everything I have read on StackOverflow nothing work so far. Any suggestions?

Sync with Gradle => Click the Gradle panel on the right side of the screen and then click the sync icon (Two arrows pointing to each other's tails, forming a circle)
Rebuild App => Click the Build option at the top of the screen, then click, "Rebuild Project"

iOS Development with Swift Techdegree Student 5,114 PointsI realized what happened: In the video "Creating a custom layout" at 4.10 Ken explains how to code the <data> ... </data> in "hourly_list_item.xml" but in the later video "Acitivity" at 3.20 you can see that <data> ... </data> appears in "activity_hourly_forecast.xml" and only when you write "data" in your code in the xml-File Android Studio creates the bindind class in the background.

iOS Development with Swift Techdegree Student 5,114 PointsAs I said above. There is an error in the brandnew video and I am surprised that Treehouse didn't respond to my post.
Fahad, just write the same <data> stuff you have written in hourly_list_item.xml in activity_hourly_forecast.xml. I hope Ken will react and correct the videos.

Courses Plus Student 10,786 PointsI did that and the error was gone, but after that, I'm not able to run my app, it's just building gradle and doesn't actually run the app on my external device, I'm using! Did you face any issues like this?

18,513 PointsOn another project, I was having the same horrible refusal to import ..... per https://stackoverflow.com/a/39549387, I restarted Android Studio, then rebuilt the project -- and there was my com.example.project.databinding, all ready to be imported! Hope that helps!

Treehouse TeacherApologies on the slow response here! Ken left Treehouse for an exciting opportunity with MongoDB this past summer, so I'm catching up on some issues like this that have fallen through the cracks. For future students, I've added an instruction step to remedy this issue: https://teamtreehouse.com/library/android-lists-and-adapters-2/displaying-lists-of-data/binding-data-in-the-activity

Treehouse Moderator 91,252 PointsThat's brilliant Ben, thanks for this. I'm sure this will help out future students
I did end up solving the issue in the end (although kind of by accident). So later on I'll investigate and see if I can link this up in other threads where this issue came up.
