Saving image from ImageView to storage

I followed the answers of Saving an image from ImageView into internal storage but I still can't save anything.. My code is here :

 public void buttonPickImage(View view) {

        FileOutputStream fos;

        bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();

        Random rng = new Random();
        int n = rng.nextInt(1000);




        try {

            File sdCard = Environment.getExternalStorageDirectory();
            File dir = new File(sdCard.getAbsolutePath() + "/BAC");
            bool = dir.mkdir();

            File file = new File(dir, "BAC_"+n+".jpg");


            fos = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.JPEG,100,fos);
            fos.flush();
            fos.close();
            Toast.makeText(getApplicationContext(),"Image sauvegardée"+bool,Toast.LENGTH_SHORT).show();

        }catch (java.io.IOException e){
            e.printStackTrace();
            Toast.makeText(getApplicationContext(),"IOException: " + e.getMessage(),Toast.LENGTH_SHORT).show();
        }

    }

With this method I get the IOExeception with messae : java.io.FileNotFoundException: /storage/emulated/0/BAC/BAC_396.jpg: open failed: ENOENT (No such file or directory)

I also tried this to save it to internal storage but its not working for me : https://www.tutorialspoint.com/how-to-write-an-image-file-in-internal-storage-in-android With this method, program runs but boolean mkdir gives me false.

Thanks for helping me

Finally got it working using Media Store instead of getExternalStorageDirectory as

This method was deprecated in API level 29. To improve user privacy, direct access to shared/external storage devices is deprecated. When an app targets Build.VERSION_CODES.Q, the path returned from this method is no longer directly accessible to apps. Apps can continue to access content stored on shared/external storage by migrating to alternatives such as Context#getExternalFilesDir(String), MediaStore, or Intent#ACTION_OPEN_DOCUMENT.

MediaStore is also useful as it allows you to get the image in your android gallery app.

So my solution is :

ImageView imageView = findViewById(R.id.image);
        Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();

        ContentValues values = new ContentValues();
        values.put(MediaStore.Images.Media.TITLE, "any_picture_name");
        values.put(MediaStore.Images.Media.BUCKET_ID, "test");
        values.put(MediaStore.Images.Media.DESCRIPTION, "test Image taken");
        values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
        Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
        OutputStream outstream;
        try {
            outstream = getContentResolver().openOutputStream(uri);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 70, outstream);
            outstream.close();
            Toast.makeText(getApplicationContext(),"Success",Toast.LENGTH_LONG).show();
        } catch (IOException e) {
            e.printStackTrace();
            Toast.makeText(getApplicationContext(),e.getMessage(),Toast.LENGTH_LONG).show();
        }

Still thank you @blackapps for explaining me some basics things about the IOexception, mkdir and toasts. It'll be useful anyway.
