Question

Look this startActivityForResult() codes, this function was deprecated. How to change this codes in Fragment?

What's mean "Call Activity.startActivityForResult(Intent, int) from the fragment's containing Activity."??

Please, simply guide to me...

private const val REQUEST_PHOTO = 2

class ExampleFragment:Fragment(), DatePickerFragment.Callbacks {

    private lateinit var photoUri : Uri

    override fun onStart() {
        super.onStart()
        ...

        photoButton.apply {
            val packageManager : PackageManager = requireActivity().packageManager

                val captureImage = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
            val resolvedActivity : ResolveInfo? =
                packageManager.resolveActivity(captureImage,
                PackageManager.MATCH_DEFAULT_ONLY)

            if (resolvedActivity == null) {
                isEnabled = false
            }

            setOnClickListener {
                captureImage.putExtra(MediaStore.EXTRA_OUTPUT, photoUri)

                val cameraActivities : List<ResolveInfo> =
                    packageManager.queryIntentActivities(captureImage, PackageManager.MATCH_DEFAULT_ONLY)

                for (cameraActivity in cameraActivities) {
                    requireActivity().grantUriPermission(
                        cameraActivity.activityInfo.packageName,photoUri,
                        Intent.FLAG_GRANT_WRITE_URI_PERMISSION
                    )
                }
                startActivityForResult(captureImage, REQUEST_PHOTO)  // <<<< Deprecated 
            }
        }
    }

First create a variable of type ActivityResultLauncher called captureImageLauncher

You have to register a result callback: (which is the alternative of the previously used onActivityResult method) like this. So you can move all your code which was under onActivityResult here in this callback

private val captureImageLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
        result: ActivityResult ->
        
        // Here You handle the result that the activity sent back
        // You can use methods like result.resultCode or result.data to retrieve information
    }

This will create an ActivityResultLauncher that You will use later instead of startActivityForResult like this:(instead of the startActivityForResult method. You also won't be needing an explicit request code because it makes thing unnecessarily complicated)

captureImageLauncher.launch(captureImage) // captureImage is the intent that You've created
