    public void pick(AndroidViewComponent layout, String imagePath) throws Exception {
      InputStream in;
       try{
           in = container.$form().openAssetForExtension(imagePath);
       } catch (IOException e) {
} finally {
              in.close();
           }
          Bitmap bmp = BitmapFactory.decodeStream(in);
    Image img = (Image) bmp;
    setImage(img);
                }

@DevYB sur, your code is not working. it store nothing in in InputStream.

it gives me a error - in.close on a null object reference

This may help you to directly get image(bitmap) from any path or asset
MediaUtil.getBitmapDrawable(form, imageURI).getBitmap();

@Atom_Developer what’s wrong with my code?

@SimpleFunction(description = "")
   public void pick(AndroidViewComponent layout, String imageURI) {
     Drawable drawable = MediaUtil.getBitmapDrawable(container.$form(), imageURI).getBitmap();
     View view = layout.getView();
     view.setImageDrawable(drawable);
   }

i think the code , provided by @Atom_Developer is returning a bitmap

#94

so you cannot use this .

Drawable drawable =MediaUtil.getBitmapDrawable(container.$form(), imageURI).getBitmap();

use this something like that

Bitmap drawable =MediaUtil.getBitmapDrawable(container.$form(), imageURI).getBitmap();

actually I love drawable more than Bitmap :sweat_smile:

#97

btw, you can convert the bitmap to drawable. using this method

Drawable drawable = new BitmapDrawable(getResources(), bitmap);

but it is easy to use @Atom_Developer code. Go for it

Q2. Do You Want User Input Name Of Assets Image And Show It In Given Arrangement With Image ?

Q3. Or Do You Just Want To Pass The Name Of Assets And User Can Set It In ImageView Component That’s In Build
