Get image bitmap from image view to Kotlin base64 , always octet-stream instead of image/png

Question

Case:

I would like to upload the image byte array with defining the type as image/ png. When it comes to execution in practice, I get the image from my Google Photo and converted as octet-stream

When I try to use Picasso / Glide library to extract the base64 string. it cannot work. I want to find out the way to generate the proper base64 string but it goes in vain and found an exception: bad base64 String.

Would you please tell me the way to convert the image to a proper base64 string and decode an image successfully?

I save the selected image to save as file called avatar.png.

Here is my code to convert From file to byteArray :

  fun convertFileToBase64 (file : File)  : ByteArray{
    val byteArray = IOUtils.toByteArray(bitmap)
    return byteArray
}

Here is my code to convert the base64 string to image using Glide

user.avatar is a base64 string 
             Glide.with(this).asBitmap().load(user.avatar).apply(RequestOptions().placeholder(R.drawable.my_icon).fitCenter()).into(
                     profile_image
             )

what is `IOUtils.toByteArray`? It is not a part of ANdroid SDK — Vladyslav Matviienko, Dec 03 '18 at 06:35
I use this module for convert from my image bitmap to the byte array https://commons.apache.org/proper/commons-io/javadocs/api-release/org/apache/commons/io/IOUtils.html — Jeff Bootsholz, Dec 03 '18 at 06:35
there is no overload of `toByteArray` method, which accepts a `Bitmap` there — Vladyslav Matviienko, Dec 03 '18 at 06:39
Before that I tried to create the file as avatar.jpg and write the bytes to this file, then I use this method IOUtils.toByteArray(file : File ) . See edited — Jeff Bootsholz, Dec 03 '18 at 06:43
https://stackoverflow.com/a/36791309/1568530 here is the way to do that in `Java`. SHould be easy to convert to kotlin — Vladyslav Matviienko, Dec 03 '18 at 06:46
how to reduce the size of bitmap ? shrinking the width and heigh or compress to lower ratio ? — Jeff Bootsholz, Dec 05 '18 at 09:42
that is totally another question, but fif you are using `bitmap.compress`, then both should work. — Vladyslav Matviienko, Dec 05 '18 at 10:53
