Attempting to launch an unregistered ActivityResultLauncher crash

Question

I have registered launcher before activity get started but some times when launch is called on listener it gets crashed and reason is mentioned below

Sometimes I am getting this:

java.lang.IllegalStateException: Attempting to launch an unregistered ActivityResultLauncher with contract j.c@ab78423 and input Intent You must ensure the ActivityResultLauncher is registered before calling launch().

any solution?

I am following below approach :

1. Creating launcher variable for activityResultLauncher before activity is created

private var launcher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result -> // handling result }

2. And launching this after activity is created by using below method: launcher.launch()
