Hi Rahul, I'm a Internet and Information Technology Major from Queensborough Community College located from Bayside, NY and my professor wanted me to come up with a Term Project for Java Programming and I asked him if I can work my project using Kotlin, and he replied with "yes," So I decided to make a Kotlin Term Project and so I ended up watching this particular video, but I just realized that you're using Android Studio 3.1.2 and I'm using Android Studio Arctic Fox, Version 2020.3.1 Patch 4. You've done a wonderful job trying to put all of the codes. Also, it is well explained. Thank you so much Rahul and please keep up the good work! Sincerely, Kenny

Completed this while coding along. Added some additional features and this was totally informative and fun for a beginner. Man, you are simply the best at this, thanks!

[@GreenSlugg]

Thank you for this video! I keep using it for reference. Also, you are very handsome my friend! That is a huge benefit on KZbin.

Very well explained, Rahul. Thank you so much for this, it's helping with my mobile app development class. I always find it fascinating when I find students or new grads that teach better than professors.

I'm running Android Studio 4.1 and @ 42:47 when you open up the styles.xml, I do not have that file, I have checked all of the directories even under the Project setting instead of android. I was able to find themes.xml which I was able to change the header color and the background color, but the colorPrimaryDark and colorAccent didn't change anything that I could tell. The seekBar is still blue/green as well as the base line. Any ideas? Thank You!

[@RahulPandeyrkp]

This is also due to the Android Studio 4.1 update. styles.xml is now themes.xml. Can you play around with the colorPrimary defined in themes (along with other colors)? One of them should update the other colors you mentioned. Further reading in the "Material Design Components updates": android-developers.googleblog.com/2020/10/android-studio-41.html

[@darrinreed8027]

@@RahulPandeyrkp Ah, yes I did add some stuff to the colors and then the theme file, one worked, I'll have to look at it again when I get the chance. Thank You!

Hello, when calling the seekBarTip in the MainActivity just passes the saved instance state, the seekBarTip remains red and states it needs to be abstract. I've noticed it does it with the other textView and IDs. I've noticed it doing this the last few days with other apps I've tried. I did update the android studio recently, but I dont know if that's when it started. Also when I would rename the textView IDs, I had a screen pop up to rename and refactoring the ID, I didnt see that popup on your video. Any ideas as to what's wrong? Should I uninstall and reinstall the android studio? Thank You!

[@RahulPandeyrkp]

Interesting! Are you running Android Studio 4.1? Could you open the build.gradle file and tell me what plugins you have? Make sure you add the following lines at the top of that file: apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions'

[@darrinreed8027]

@@RahulPandeyrkp it had com.android.application, kotlin-android. I just added the kotlin-android-extensions And it seems to be working as it should now. Thank You for the fast response!

[@adamdeane4675]

Hi, my computer struggling to run both IDE and emulator at the same time. Is it good idea to use my android phone to run the app I wrote?

[@RahulPandeyrkp]

yep, if your computer is struggling, hooking up a physical Android device is a great idea.
