My list is showing an the empty message. What's the best way to find the error? How do I use the debugger to solve this?

I'm getting the "There is no data to display" after completing this video.

Thanks this fixed it. Added the code you mentioned under DailyForecastActivity.java; seems that we made the new adapter but didn't use it.

This should be in the teacher's notes to alert others about the problem.

Thank you so much!

Thanks! This was the problem for me, too!

I added the line setListAdapter(adapter); in the DailuForecastActivity but when I clicked the Daily button the app stopper. The error I get is this:

CAN SOMEONE PLEASE HELP ME?? THANKS!!!

I just copy paster the XML for the layouts on the project in the teachers notes and then it worked. Apparently there is some mistake on the XML presented on the videos as compared to the project in the teachers notes.

thanks!

This was exactly my issue too. Thanks Horatio. I'm surprised this isn't in the teacher notes or a popup on the video.

After adding the line Heratio mentioned I was then getting the crash that marcel had. I fixed it by going into the activity_daily_forecast xml and changing the layout width and height to match_parent instead of wrap_content. I don't know if I missed it during the videos or if it wasn't mentioned but that seems to have fixed the issue for me.
