Kotlin Android start new Activity

Question

I want to start another activity on Android but I get this error:

Please specify constructor invocation; classifier \'Page2\' does not have a companio

Answer 1

You have to give the second argument of class type. You can also have it a little bit more tidy like below.

startActivity(Intent(this, Page2::class.java).apply {
    putExtra("extra_1", value1)
    putExtra("extra_2", value2)
    putExtra("extra_3", value3)
})
