If you want to assign dynamic bitmap image to bitmap variables  Example for kotlin  backgroundImage   Glide with applicationContext  asBitmap   load PresignedUrl   getUrl items   position  img   into 100  100  get      The above answers did not work for me    asBitmap should be before the  load  http

It looks like overriding the Target class or one of the implementations like BitmapImageViewTarget and overriding the setResource method to capture the bitmap might be the way to go     This is untested   -       Glide with context            load  http   goo gl h8qOq7             asBitmap             into new BitmapImageViewTarget imageView                          Override                      protected void setResource Bitmap resource                                Do bitmap magic here                          super setResource resource

I m not familiar enough with Glide  but it looks like if you know the target size  you can use something like this   Bitmap theBitmap   Glide          with this           load  http                   asBitmap            into 100  100      Width and height         get      It looks like you can pass -1 -1  and get a full size image  purely based on tests  can t see it documented    Note into int int  returns a FutureTarget lt Bitmap gt   so you have to wrap this in a try-catch block covering ExecutionException and InterruptedException  Here s a more complete example implementation  tested and working   class SomeActivity extends Activity        private Bitmap theBitmap   null        Override     protected void onCreate Bundle savedInstanceState               onCreate stuff             final ImageView image    ImageView  findViewById R id imageView            new AsyncTask lt Void  Void  Void gt                   Override             protected Void doInBackground Void    params                    Looper prepare                    try                       theBitmap   Glide                          with SomeActivity this                           load  https   www google es images srpr logo11w png                            asBitmap                            into -1 -1                           get                       catch  final ExecutionException e                         Log e TAG  e getMessage                        catch  final InterruptedException e                         Log e TAG  e getMessage                                         return null                             Override             protected void onPostExecute Void dummy                    if  null    theBitmap                           The full bitmap should be available here                     image setImageBitmap theBitmap                       Log d TAG   Image loaded                                               execute                Following Monkeyless  suggestion in the comment below  and this appears to be the official way too   you can use a SimpleTarget  optionally coupled with override int int  to simplify the code considerably  However  in this case the exact size must be provided  anything below 1 isn t accepted    Glide      with getApplicationContext         load  https   www google es images srpr logo11w png        asBitmap        into new SimpleTarget lt Bitmap gt  100 100             Override         public void onResourceReady Bitmap resource  GlideAnimation glideAnimation                image setImageBitmap resource      Possibly runOnUiThread                       as suggested by  hennry if you required the same image then use new SimpleTarget lt Bitmap gt
