Build Your First Android App - Tip Calculator Beginner Tutorial

Build an Android tip calculator app! After you enter a base amount and a tip percentage, the app will calculate the tip and total for you. We also implement a tip percentage animation and a footer to make our app more unique. This is the perfect first app to build if you're new to Android.

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!

Alright, let's see how this full video meta goes.

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!
