    i have the same problem but resolve using this code

实现此库实施'com.squareup.okhttp3：okhttp：3.4.1'

    static OkHttpClient mClient;
    static JSONArray jsonArray;
    static Context context;
    static String messageStr = "";



     public static void sendNotification(Context mContext,String mMessage,final JSONArray jsonArray1) {

            mClient = new OkHttpClient();
            context = mContext;
            messageStr = mMessage;

            jsonArray = jsonArray1;

            new MyTask().execute();

        }




 static class MyTask extends AsyncTask<String, String, String> {

        @Override
        protected String doInBackground(String... params) {


            try {

                for (int i = 0; i < jsonArray.length(); i++) {

                    JSONObject root = new JSONObject();
                    JSONObject notification = new JSONObject();
                    notification.put("text", messageStr);


                    notification.put("title", "Cell Command");
                    notification.put("line1", R.mipmap.ic_launcher);
                    notification.put("line2", "high");

                    root.put("to", jsonArray.get(i));
                    root.put("data", notification);


                    String result = postToFCM(root.toString());
                    Log.d("Main Activity", "Result: " + result);
                    return result;
                }
            } catch (Exception ex) {
                ex.printStackTrace();
            }
            return null;

        }

        @Override
        protected void onPostExecute(String result) {

            if (result != null) {
                try {
                    JSONObject resultJson = new JSONObject(result);

                } catch (JSONException e) {
                    e.printStackTrace();
                    Toast.makeText(context, "" + e.toString(), Toast.LENGTH_SHORT).show();
                }
            }
        }
    }


    static String postToFCM(String bodyString) throws IOException {

        final String FCM_MESSAGE_URL = "https://fcm.googleapis.com/fcm/send";

        final MediaType JSON
                = MediaType.parse("application/json");

        RequestBody body = RequestBody.create(JSON, bodyString);
        Request request = new Request.Builder()
                .url(FCM_MESSAGE_URL)
                .post(body)
                .addHeader("Authorization", "key=" + "put your firebase legacy key")
                .build();
        Response response = mClient.newCall(request).execute();
        return response.body().string();
    }

在jsonarray内部放入设备令牌希望对您有帮助。
