Share an image using a memory stream or byte array

Question

I have some standard code to share an image in my Android app. The image exists on the storage and I provide an URI to the image. This all works fine.

However, this requires the WRITE_EXTERNAL_STORAGE permission. Is there a way I can share an image without the need of this permission, for example, to not save the image to storage, but specifying a memory stream or byte array?

Thanks!

You can convert an image file to a byte array with the following code, which I taken from an answer to a similar question: How to convert image into byte array and byte array to base64 String in android?

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray();

Optional step to encode in Base64

encImage = Base64.encodeToString(b, Base64.DEFAULT);
