how to convert from image to short string?

I use Base64 system for encode from image to string this code

Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, stream);
        byte[] image = stream.toByteArray();            
        String img_str = Base64.encodeToString(image, 0);

and decode this code

byte[] decodedString = Base64.decode(decode, Base64.NO_WRAP);
            Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
            imageView.setImageBitmap(decodedByte);

but string is too long, very very long. I can't use this way. How can I do short string ?,

You can't. Images typically contain a lot of data. When you convert that to text as base64 it becomes even bigger (4 characters for every 3 bytes). So yes, that will typically be very long if it's a large image.

You could compress the image more heavily in order to reduce the size, but eventually it will be hard to even recognize as the original image - and may well be quite large even so.

Another way of reducing the size in bytes is to create a smaller image in terms of the number of pixels - for example, shrinking a 1000x1000 image to 100x100... is that an option in your case?

You haven't given us much context, but could you store the data elsewhere and then just use a URL instead?
