Android Studio -Covert bitmap to byteArray

Question

Can someone please tell how I can convert this bitmap to byteArray?

Here is the code

    if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {

        Uri uri = data.getData();

        try {
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
            // Log.d(TAG, String.valueOf(bitmap));
            EventBus.getDefault().post(new MessageEvent.SendMessage(contact.getJid(), null, ""));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Try something like this:

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

Bitmap bmp = intent.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
