excepto WhatsApp, mi aplicación está compartiendo contenido con todas las demás aplicaciones, como el correo de Hangouts, Messenger, etc. Mi SDK de compilación y SDK de destino es 23

este es mi código

if (url.startsWith("share://")) {
            Intent share = new Intent(Intent.ACTION_SEND);
            Uri requestUrl = Uri.parse(url);
            String pContent = requestUrl.toString().split("share://")[1];
            String pasteData = pContent+"";
            share.setAction(Intent.ACTION_SEND);
            share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            Toast toast=Toast.makeText(getApplicationContext(),pasteData, Toast.LENGTH_LONG);
            toast.setMargin(50,50);
            toast.show();
            StringBuilder sb = new StringBuilder();
            String [] parts = pasteData.split("<br />");
            for (int i = 0; i < parts.length; i++) {
                String part = parts[i];
                sb.append(part);
                sb.append('\n');
            }
            share.putExtra(android.content.Intent.EXTRA_TEXT, (Serializable) sb);
            share.setType("*/*");
            startActivity(Intent.createChooser(share, "Share On"));
            return true;

déjame aclarar, este código está funcionando (compartir contenido) bien para todas las demás aplicaciones pero no en WhatsApp
