Kotlin: How to convert image uri to bitmap

Question

Most of the answers are in Java I manage to find this solution in Kotlin but it didn't work for me. I also tried finding documentation but I couldn't find one What I'm trying to do is to select photo from gallery and then I want to convert Uri to Bitmap and then save it to the Room Database.

I would like to have a code similar to that but in Kotlin

Uri imageUri = intent.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(),imageUri);
Imageview my_img_view = (Imageview ) findViewById (R.id.my_img_view);
my_img_view.setImageBitmap(bitmap

@m0skit0 Didn't automatically convert to me . Usually converts if I have more lines of code. — Edita Komarova, Aug 18 '21 at 23:26

Use this:

val imageUri: Uri = intent.data;
val bitmap: Bitmap = MediaStore.Images.Media.getBitmap(c.getContentResolver(), Uri.parse(imageUri))
val my_img_view = findViewById(R.id.my_img_view) as Imageview 
my_img_view.setImageBitmap(bitmap)

What does the value c represent in c.getContentResolver()? – CWD May 01 '22 at 07:07
Context c or you can use this depending on what you are using if activity then this is fine – Hascher May 01 '22 at 10:56

As of Oct 2022:

Since MediaStore.Images.Media.getBitmap is deprecated, here is another option (from within a Fragment):

val imageUri: Uri = intent.data
val source = ImageDecoder.createSource(requireActivity().contentResolver, imageUri)
val bitmap = ImageDecoder.decodeBitmap(source)
val my_img_view = findViewById(R.id.my_img_view) as Imageview 
my_img_view.setImageBitmap(bitmap)
