    I will develop a fault-tolerant application in Kotlin using Foreground Service (with a pinned notification) and NotificationListenerService for continuous interception of pushes and their JSON routing to your webhook.

    What method do you plan to use to bypass the system notification grouping from Telegram, when multiple quick signals in a row cause Android to collapse them into a single system notification like "You have 3 new messages," resulting in your webhook receiving a useless placeholder text instead of a critically important trading signal, and you miss the deal?

    I will also provide instructions for disabling OEM battery optimization (MIUI, OneUI) so that the system does not kill the parser in sleep mode. I am ready to discuss the budget and exact deadlines in private correspondence.

    Good day! We have reviewed your project and are ready to implement a stable Android application service for intercepting notifications and sending data to a webhook in JSON format. We have experience in developing background services, Android automation, and working with system notifications.

    We propose to implement:
    • The first screen with settings:
    — Device ID field
    — URL Webhook field
    — Save button (locally on the device)
    • Start button — to launch the background service
    • Background operation after launch
    • Interception of incoming phone notifications through Notification Listener Service
    • Sending notifications to your webhook in JSON format
    • Stable processing of Telegram notifications / TG channels
    • Auto-start after device reboot (if desired)
    • Error logs / service status

    Programming language we will use:
    • Kotlin (recommended, modern and stable Android stack)
    or Java (if required)

    We can customize the JSON format to your requirements: text, source, time, package name, title, etc.

    Timeline: 2–5 days depending on testing details.
    Cost: we are ready to discuss a reasonable budget after clarifying the Android version and requirements for the webhook.

    We are ready to start quickly and deliver a turnkey working solution.

    I am implementing it in Kotlin (Android Studio, min SDK 26).

    Under the hood, NotificationListenerService will work, which the system binds itself after the user grants permission in the settings. The application intercepts onNotificationPosted, extracts package_name, title, text, and timestamp, and sends a POST to the specified webhook via OkHttp. For Telegram, I separately handle grouped notifications to avoid duplicates.

    To prevent the system from killing the process, the service starts as a foreground service with a constant notification plus WakeLock during the sending time. After the phone is rebooted, it automatically starts through the BOOT_COMPLETED receiver. For Xiaomi, Samsung, and similar devices, I will add instructions for autostart and battery whitelist, as these restrictions cannot be bypassed programmatically.

    On the settings screen, there are two fields (device_id, webhook URL), a save button, and a start button with a check for notification reading permission.

    Deadline: 5 days
    Price: 5000 UAH, final after detailed discussion of the technical specifications

    Question: Is an auth header needed in the POST request, or is it enough to send plain JSON?

    Hello! The task of creating a notification catching service is clear to me and fully feasible. I will develop an application that will work as a background service on Android, using NotificationListenerService for instant interception of incoming signals, including from Telegram channels. I will implement a settings screen with local storage for Device ID and Webhook URL, as well as the logic for forming and sending JSON packets with each new event. Special attention will be paid to the stability of operation in the background, so that the system does not unload the service from memory. For the application to work correctly, you will not need a complex infrastructure; any endpoint for receiving POST requests will be sufficient, and the installation on devices will be as simple as possible through the installation of an APK file. Please note that for 24/7 operation, it may be necessary to host your Webhook handler on a stable server, with which I can also assist. The cost of turnkey development will be 4500, and the completion time is 3 days. I am ready to discuss the structure of the JSON file and start writing the code.

    Hello!
    I am ready to implement an Android application according to the technical specifications:
    ✔ Settings screen (Device ID + Webhook URL)
    ✔ Local data storage
    ✔ Button to start the background service
    ✔ Interception of all notifications through NotificationListenerService
    ✔ Correct handling of Telegram notifications (including channels)
    ✔ Sending data to the webhook in JSON format
    ✔ Stable operation in the background (foreground service, auto-restart if necessary)
    Additionally, I can:
    add logging for monitoring sending
    implement resending in case of network error
    create a minimalist and neat UI
    💰 Cost:
    3000–4000 UAH (depending on final requirements)
    ⏳ Deadline:
    2–4 days
    I am ready to discuss the details. Reasonable negotiation is possible.

    5 days90 USD

    Good day. I am implementing a native Android application in Kotlin in Android Studio, min SDK 26.

    I will create a settings screen with two fields: device_id and webhook URL, saving locally on the device. To intercept notifications, I will use NotificationListenerService — the application will receive notifications, including from Telegram, take package_name, title, text, timestamp, and send them via a POST request to the specified webhook in JSON format.

    I will make the service work in the background through a foreground service, and I will add auto-start after reboot through BOOT_COMPLETED. For Samsung/Xiaomi and other interfaces, I will provide a short instruction on enabling auto-start and disabling battery restrictions, as these are system limitations of Android.

    I will also add a start button, check for notification access permission, and basic error handling when sending the webhook.

    Deadline: 5 days.
    Cost: 4000 UAH.

    Чому? 

  • Oleksandr Nekrutenko
    1 May, 9:44 |

    Реалізація такого додатка технічно можлива, але існують критичні нюанси та обмеження сучасних операційних систем (особливо Android), через які розробники часто відмовляються від таких замовлень або попереджають про нестабільність.

    Ось основні причини, чому це складно реалізувати так, щоб воно працювало «ідеально»:

    1. Обмеження фонової роботи (Doze Mode)

    Сучасні версії Android (починаючи з 6.0 і особливо в 12-14) мають дуже агресивні механізми енергозбереження.

    • Проблема: Система «присипляє» додатки, які споживають ресурси у фоні. Щоб сервіс працював стабільно, користувачеві доведеться вручну вимикати оптимізацію батареї саме для цього додатка.

    • Рішення: Використання Foreground Service з постійним сповіщенням у шторці (рядок «Додаток працює у фоні»), інакше система вб’є процес через 10-15 хвилин.

    2. Доступ до сповіщень (Notification Listener Service)

    Для відловлювання повідомлень використовується спеціальний API — NotificationListenerService.

    • Конфіденційність: Google Play дуже суворо ставиться до додатків, які читають сповіщення. Якщо ви плануєте розміщувати це в магазині, додаток, швидше за все, заблокують як шпигунське ПЗ (Spyware).

    • Стабільність: На деяких китайських прошивках (MIUI, HyperOS, ColorOS) цей сервіс може самовільно вимикатися системою безпеки.

    3. Специфіка Telegram

    Хоча ви вказали, що потрібно ловити сигнали з ТГ-каналів, тут є «підводний камінь»:

    • Якщо канал стоїть на Mute (без звуку), сповіщення може не створюватися в системі взагалі або не містити повного тексту.

    • Якщо приходить декілька повідомлень поспіль, Android може згрупувати їх у «пакет», і дістати текст конкретного нового повідомлення з масиву даних стає технічно складніше.

    4. Безпека та JSON-webhooks

    Відправка кожного сповіщення на зовнішній URL потребує:

    • Обробки помилок мережі (якщо інтернет зник, повідомлення втрачається, якщо не реалізувати локальну чергу/базу даних).

    • Врахування затримок (Latency), що критично для «сигналів».
