#4. How to move to New Activity on Button click | Intents | Android Development Tutorial 2021

Sir ab android studio me default text size 14 sp hota hai

Basically kotlin is a enhanced and optimised language of java🤔

Help
I got error
Val name =nameInput.editableText.toString()
Show unresolved reference nameInput

Finally made my first app! 🥳 Thank you so much bhaiya 🙏🏻

In Java, there is no direct equivalent to Kotlin's companion object. However, you can achieve similar functionality by using a static inner class.

You should shame on your self you purposely wasteing our time

Text is not coming in cursive , how to resolve it ?

You create problems in your videos to solve later on your comments 🤣
