I have included 'share via myApp' option. I inserted following code in the receiving activity class.

    // Get the intent that started this activity
    Intent intent = getIntent();
    Uri data = intent.getData();

    // Figure out what to do based on the intent type
    if (intent.getType().indexOf("image/") != -1) {
        // Handle intents with image data ...
}

What is the next step to retrieve bitmap image.

This is work for me

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK)
{
    Uri imageUri = data.getData();
    Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
}
}

You can try this. You can call setPic() in onActivityResult method. I have used this in an application to take photos an put it in an ImageView.

private void setPic() {

    //currentPhotoPath contains path of image file.
    //visorFoto is a reference to an ImageView object.
    File file = new File(currentPhotoPath);
    Uri imageUri = Uri.fromFile(file);
    visorFoto.setImageURI(imageUri);

Once u have the Uri, you can use something like:-

fun getBitmapFromUri(context: Context, uri: Uri): Bitmap? {
        
        var parcelFileDescriptor: ParcelFileDescriptor? = null
        return try {
            parcelFileDescriptor = context.contentResolver.openFileDescriptor(uri, "r")
            val fileDescriptor: FileDescriptor? = parcelFileDescriptor?.fileDescriptor
            val image = BitmapFactory.decodeFileDescriptor(fileDescriptor)
            parcelFileDescriptor?.close()
            image
        } catch (e: Exception) {
            //Log.e(TAG, "Failed to load image.", e)
            null
        } finally {
            try {
                parcelFileDescriptor?.close()
            } catch (e: IOException) {
                e.printStackTrace()
                //Log.e(TAG, "Error closing ParcelFile Descriptor")
            }
        }
    }

referring to Android Developers documentation you can use this to get bitmap from an URI

    ....

    Uri uri = intent.getData();
    try {
        Bitmap bitmap = getBitmapFromUri(uri);
        // do something with this bitmap

    } catch (IOException e) {
        e.printStackTrace();
    }
}


private Bitmap getBitmapFromUri(Uri uri) throws IOException {
    ParcelFileDescriptor parcelFileDescriptor = context.getContentResolver().openFileDescriptor(uri, "r");
    FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
    Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
    parcelFileDescriptor.close();
    return image;
}
