[@darkwingscooter9637]

Thank you very much! Perfect app and explanation. One useful thing to add, though, is a shuffle feature. I did it by adding the line: Collections.shuffle(questionList) ... to the Constants before returning the list. That way you get a different order each time. Hope that helps.

I'm currently in an android development class at my uni. Comming from a background in using apps like Indesign to make brand guides as well as using apps like photoshop and illustrator. I find it really interesting that the development porsses are very similar between UI and Graphic Design

[@alaskahudson]

At around the 25:00 mark of the video I ran the app and it stopped (crashed) immediately. Through a process of removing code I found that the following line was the problem. By removing it, the app ran but without an outline around the "Name" box. style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox" I eventually solved it by changing the themes.xml file to edit this line (see 23:27 in the video): to this: I am proceeding on and I am not sure if this will later present problems but it works for now.

[@Smith1311]

Yeah, i had to do the same. I was lucky that google showed StackOverflow as first when I searched for answers, where someone asked a similar question and a guy explained how the AppCompat and the Material aren't compatible. Only when I commented the story found out that others had the same problem and already wrote it down.

[@austingarrison7089]

Thank you so much!!!! I've been trying to figure out for hours why my code wouldn't run

[@thedope4901]

Very grateful you found this problem. Same problem here. I noticed that at the beginning his styles.xml was what my themes.xml file was but was slightly different. I assume something has changed with Android Studio since the video was made maybe???

[@andymukonkole]

hey thank you for this i had the same problem while running but would kindly want to ask about the button whenever i launch the app and type a name after pressing the button it doesnt take me to the second empty page i dont know why

1:23:00 I wonder why didnt you use radio buttons for answers (optionOne, optionTwo, optionThree...)? You did not have to change their styles everytime the user clicks on them. I am curious why?

I redesign the app and made some implementations of my own, but i'm trying to randomize the order of the flags, the questions and the answer on screen, do you think that is possible to do this implementation using the Constants as it is, or i have to create a Array to make it work?
