everything is worked fine. until i added the (Checking for responding activities section)
the button remained disabled despite i have a contacts app and it was working fine already.
suspectButton.apply{
val pickContactIntent = Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI)
setOnClickListener {
startActivityForResult(pickContactIntent, REQUEST_CONTACT)
}
val packageManager : PackageManager = requireActivity().packageManager
val resolvedActivity: ResolveInfo? =
packageManager.resolveActivity(pickContactIntent ,
PackageManager.MATCH_DEFAULT_ONLY)
if (resolvedActivity==null) {
isEnabled = false
}
}
The one thing that i have is different from the book code is the null safety for URI, android studio forced me to do this way
val cursor = contactURI?.let {
requireActivity().contentResolver
.query(it, queryFields, null, null, null)
}
because we had val contactURI : Uri? = data.data
in the first place…
how to fix this?
