intent in android kotlin
val intent = Intent(this,HelloActivity::class.java)
startActivity(intent)
Why do we need to add .java in the end? Isn't HelloActivity a .kt file?
ts because you are calling Java Code from the Kotlin as Intent is a Java
Class in Android which accepts .class reference as mentioned below.
Intent(Context packageContext, Class cls) Kotlin class reference is not
the same as a Java class reference. To obtain a Java class reference, use
the .java property on a KClass instance as SampleActivity::class returns
KClass which is Kotlin class not a java class. So you cannot pass Kotlin
class reference to Java (Intent in your case) and so you have to pass Java
class reference
