getting data null on registerForActivityResult

Question

So everything is worling good camera is opening and also permission dialog is opening if there i no permission, but the image is not getting displayed in the image view. because i am getting null on result.data?.data

This is my function to create path for image captured and to open camera

        fun displayCamera(activity: Activity) {
        val destPath: String? = Objects.requireNonNull(
            Objects.requireNonNull(activity).getExternalFilesDir(null)!!
        ).absolutePath

        val imagesFolder = File(destPath, activity.resources.getString(R.string.app_name))
        try {
            imagesFolder.mkdirs()
            val imgFile = File(imagesFolder, Date().time.toString() + ".jpg")
            val imagePath = FileProvider.getUriForFile(
                activity, "com.example.shoppinglist" + ".provider", imgFile
            )
            val intent = Intent(ACTION_IMAGE_CAPTURE)
            intent.putExtra(EXTRA_OUTPUT, imagePath)
            cameraResult.launch(intent)
        } catch (e: Exception) {
            e.printStackTrace()
        }
    }

2.This is my registerForActivity Result variable

          private val cameraResult = registerForActivityResult(
        ActivityResultContracts.StartActivityForResult()
    ) { result: ActivityResult ->
        if (result.resultCode == Activity.RESULT_OK) {
            binding.profilepic.setImageURI(result.data?.data)
        }
    }

3.This is the code where i am calling this function on button click

         if (checkPermissions(this@RegistrationActivity)) {
                    displayCamera(this@RegistrationActivity)
                } else {
                    requestPermission(requestMultiplePermissionLauncher)
                }

Answer 1

Your code seems to be fine but sometimes there are issue with the FileProvider if you are integrating it with the static package name and storage permission as well with different android versions.

You can try the below code which is working fine. I have saved the image bitmap to the storage and fetch the absolute path as imagePath and after fetching the path i am setting the same inside imageView.

Just change your code with the below code.

private fun displayCamera() {
    val intent = Intent(ACTION_IMAGE_CAPTURE)
    cameraResult.launch(intent)
}

cameraResult = registerForActivityResult(
        ActivityResultContracts.StartActivityForResult()
    ) { result: ActivityResult ->
        if (result.resultCode == Activity.RESULT_OK) {
            val imageBitmap = result.data?.extras?.get("data") as Bitmap
            val imagePath = saveImageToStorage(imageBitmap)
            // Here you can insert this imagePath into your room database.
            binding.profilepic.setImageURI(Uri.parse(imagePath))
        }
}

private fun saveImageToStorage(bitmap: Bitmap): String? {
    val timeStamp = SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(Date())
    val imageFileName = "JPEG_$timeStamp.jpg"
    val storageDir: File? = getExternalFilesDir(Environment.DIRECTORY_PICTURES)

    return try {
        val imageFile = File(storageDir, imageFileName)
        val fos = FileOutputStream(imageFile)
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fos)
        fos.close()
        imageFile.absolutePath
    } catch (e: IOException) {
        e.printStackTrace()
        null
    }
}
