Why Isn't My FileOutputstream Writing to a File?

I'm a beginner working on an Android app that uses the gcacace SignaturePad library to capture the signature of my user. My goal is to take the signature, compress it down into a JPEG, and then write that information to a file on the users phone so the picture can be accessed later.

I am currently getting no errors or crashes when I run the code, yet no directory or file is being created when I test the app out on my device(Google Pixel 2). Can anyone give me a hand figuring out where the problem is? I've thrown my head against a wall this entire morning and still don't know.

ContextWrapper cw = new ContextWrapper(getApplicationContext());
            File directory = cw.getDir("images", Context.MODE_PRIVATE);
            if (!directory.exists()) {
                directory.mkdirs();
            }
            File myPath = new File(directory, "1.jpg");

            FileOutputStream fOut = null;

            try {
                fOut = new FileOutputStream(myPath);
            } catch (Exception e) {
                e.printStackTrace();
            }

            signaturePad.getSignatureBitmap().compress(Bitmap.CompressFormat.JPEG, 90, fOut);
            Bitmap signature = signaturePad.getSignatureBitmap();

            int bytes = signature.getByteCount();

            try {
                fOut.write(bytes);
                fOut.flush();
                fOut.close();
            } catch (IOException ex) {
                ex.printStackTrace();
            }

            Toast.makeText(activity_signature_pad.this, "Signature Saved", Toast.LENGTH_SHORT).show();

The code in your question writes to what the Android SDK refers to internal storage. That is private to your app; ordinary users do not have access to it (including you, except when using developer tools).

You appear to want to write to external storage. For that, use:

File directory = new File(getExternalFilesDir(null), "images")
