What is com.google.android.cellbroadcastreceiver?

Android users might have noticed an activity named ‘com.google.android.cellbroadcastreceiver‘ running. This package keeps running in the background on the android device that has any kind of cellular connection.

com.google.android.cellbroadcastreceiver is the packaged name of a pre-installed android service app called CellBroadcastService. The app is responsible for handling the broadcasts in emergency and non-emergency situations to present the information to end-user based on carrier and regional regulations.

What is CellBroadcastService?

CellBroadcastService is a messaging service framework on Android devices that is designed to deliver messages to multiple mobile phone users, in a defined area, at the same time.

In fact Cell Broadcast Service messaging framework supports CellBroadcast SMS decoding, geofencing for wireless emergency alert (WEA) 3.0, message duplication checks, and broadcasting messages to apps.

Name: Cell Broadcast Service
Package Name: com.google.android.cellbroadcastreceiver
Developer: Google LLC

The CellBroadcastReceiver app is built into the Android framework starting in Android 11 (API level 28) and higher. The app features a single broadcast receiver to handle system-wide notifications, which any application can send.

What is Cell broadcast Receiver?

The Cell Broadcast Receiver app on Android provides a platform in emergency conditions for alert notification and traffic alerts. A reliable and concise app for android with an interactive multi-selection icon that allows users to use it in different emergency situations.

This app has permissive private permission because the default system behavior prevents the end-user from enabling or disabling alerting for emergency and non-emergency alerts.

What is com.google.android.cellbroadcastreceiver used for?

com.android.cellbroadcastreceiver is a package name, that works for cell broadcast receiver in android. In fact, all the apps installed on Android have their unique package name that not only helps the Android system to identify the app but it also helps the developers to differentiate between the apps.

Whenever an emergency broadcast is released from the device this starts a chain of processes from sending to receiving the SMS. The flow of a received SMS through the CellBroadcastService works in the following way.

1. Firstly, an SMS is received from the Carrier network which flows to the Modem from where it is sent to the Radio Interface Layer(RIL).
2. The Radio Interface Layer(RIL) then notifies the InBoundSMSHandler app on your device with the help of the RILNotifier app about a CDMA/GSM CellBroadcast SMS.
3. The InBoundSMSHandler sends the CellBroadcast SMS to the CBS module for parsing and processing the message.
4. Once the message is processed, CellBroadcastService sends the intent to the CellBroadcastReceiver app which then displays the message to the receiver.

How does CellBroadcastService work?

is a small helper class that receives a CellBroadcast SMS and reacts when it comes in.
1. The InboundSMSHandler is available for dialog services that require incoming SMS, like chatbots. It acts as the core interface.
2. When a message comes in, it’s forwarded to the CellBroadcast SMS module for the framework to parse and process the incoming.
   Once the CellBroadcastService receives the broadcasted intent, it will forward it to the system default CellBroadcastReceiver app. Keep in mind that if there are registered CellBroadcastReceiver apps in your system, they may also receive the broadcasted intent.
3. The CellBroadcastReceiver app(com.android.cellbroadcastreceiver package) alerts the user automatically.

What Permission Configuration Does CellBroadcast Require?

Initially, CellBroadcastReceiver app was signed using Google Signature itself instead of Android platform signature. After the rollout of Android 11 a new signature was assigned to the it. This made it easy to obtain the signature to sign the app using same key. This ensures the required SMS app permissions.

Also, restrict your app from accessing the CellBroadcast service by adding the permission for android.permission.SEND_CELLBROADCAST in its manifest and fully implementing the com.android.cellbroadcastservice.permission.C2D_MESSAGE permission in an accompanying service.

The Cell Broadcast app has a CellBroadcastContentProvider APK that allows you to override the stock CellBroadcast APK. It also preserves the current data before the legacy implementation is removed.

To migrate message history to the CellBroadcast module, the CellBroadcastContentProvider APK must support the ContentProvider.query.

The migration is done via com.google.android.cellbroadcastreceiver.

The Android Compatibility Test Suite (CTS) verifies the functionality of app-dependent system APIs. This identifies basic compatibility problems while developing apps like app crashes, runtime errors, as well as other errors and automatically removes these incompatibilities with the new API levels.

There is also a Debug Mode that allows CMAS testers to identify and solve technical issues with CMAS systems and the device end-systems. App and Device Testers can use specific access codes to enable Debug Mode on certain end devices.

com.android.cellbroadcastreceiver — это имя пакета, работает для приемник сотового вещания в android. Теперь вам нужно знать, что такое сотовое вещание.

Что такое Castreceiver сотовой связи?

Приложение CellBroadcastReceiver предоставляет (используется для) платформу для уведомлений о чрезвычайных ситуациях и предупреждений о дорожном движении. Он предлагает уникальный опыт для пользователей, а приложение имеет особый стиль. И у него есть несколько значков, чтобы различать типы предупреждений. К тому же система CellBroadcastReceiver очень надежна и лаконична. Это приложение имеет разрешающее частное разрешение, потому что поведение системы по умолчанию не позволяет конечному пользователю включать или отключать оповещения для экстренных и неэкстренных оповещений.

Как это работает?

1. InboundSMSHandler — это небольшой вспомогательный класс, который получает SMS-сообщение CellBroadcast и реагирует на его поступление. InboundSMSHandler доступен для диалоговых служб, которым требуется входящее SMS-сообщение, например для чат-ботов. Он действует как основной интерфейс.
2. Когда приходит сообщение, оно пересылается в модуль SMS CellBroadcast для фреймворка для анализа и обработки входящего.
3. Как только CellBroadcastService получит транслируемое намерение, он направит его в приложение CellBroadcastReceiver по умолчанию. Имейте в виду, что если в вашей системе есть зарегистрированные приложения CellBroadcastReceiver, они также могут получать транслируемое намерение.
4. Приложение CellBroadcastReceiver ( com.android.cellbroadcastrece я вер package) автоматически предупреждает пользователя.

Какая конфигурация разрешений требуется?

Android O запрещает системным приложениям получать сообщения CellBroadcast. Чтобы получить доступ к этой функции при использовании стандартных API Android (тех, которые работают в рамках), создайте новую библиотеку Android, которая включает все необходимые компоненты, и войдите в свое приложение вместо подписи платформы. Кроме того, ограничьте доступ вашего приложения к службе CellBroadcast, добавив разрешение для android.permission.SEND_CELLBROADCAST в своем манифесте и полностью реализует разрешение com.android.cellbroadcastservice.permission.C2D_MESSAGE в сопутствующей службе ».

Как com.android.cellbroadcastreceiver интегрируется с приложением для обмена сообщениями?

Теперь вы можете напрямую связываться с приложением CellBroadcast как через приложения, так и через приложения для обмена сообщениями. С помощью этой функции вы сможете добавлять критические предупреждения в виде цепочки сообщений в предпочитаемом вами приложении для обмена сообщениями, а также открывать весь список аварийных предупреждений из CellBroadcast. Кроме того, приложение позволяет вам связываться с существующими приложениями для обмена сообщениями и социальными сетями, чтобы вы могли получать оповещения прямо в своем приложении. Для пользователей Android это новая функция в разделе «Настройки»> «Дополнительно»> «Аварийное оповещение».

Если вы хотите использовать свое приложение и по-прежнему использовать действие CellBroadcast List, определите имя компонента: com.google.android.cellbroadcastreceiver / com.android.cellbroadcastreceiver.

Это позволяет вам запускать определенные действия в вашем приложении с экрана входа в учетную запись Google всякий раз, когда появляется экстренное сообщение сотовой связи, которое влияет на любое из ваших приложений. Видишь не зарегистрирован в сети.

Чтобы запустить приложение

1. Приложение "Настройки" — это центральное место для управления настройками вашего устройства. Вы можете получить доступ к приложению «Настройки» из меню приложений.
2. Используемое вами приложение, такое как приложение для SMS, которое включает в себя вашу историю сообщений CellBroadcast.
3. Изготовитель оборудования добавил значок на главный экран.

Включение секретного кода CMAS

Служба CMAS жизненно важна только для вашего сотового телефона или мобильного устройства, получающего сообщения экстренного оповещения — она ​​не влияет на другие функциональные возможности устройства на стороне пользователя. Следовательно, вам не нужно беспокоиться о возможностях управления услугами CMAS (или их отсутствии) в выбранных вами приложениях.

Когда возникает чрезвычайная ситуация, сеть CMAS используется для максимально быстрой передачи информации о местоположении спасательным командам. Вы можете включить секретный код CMAS, набрав *#*#2627#*#*. После того, как вы отправите уникальный код номеронабирателя, появится простое сообщение о том, что секретный код CMAS включен.

Перенос данных

В новой версии Android есть модуль под названием «CellBroadcast», который может сохранять пользовательские настройки в случае замены оборудования. Устройства под управлением Android 11 должны использовать новое приложение CellBroadcast в своей сборке. APK CellBroadcastContentProvider позволяет переопределить APK стандартного вещания сотовой связи в зависимости от конфигурации оборудования и пола. Это также гарантирует, что вы сохраните текущие данные перед удалением устаревшей реализации. Вы можете создать поставщика контента, используя ADB или DDMS. Большая часть миграции выполняется через com.android.cellbroadcastreceiver.

Тестирование

Пакет Android Compatibility Test Suite (CTS) проверяет системные API, зависящие от приложений. Он выявляет проблемы совместимости в приложениях, такие как сбои или другое неправильное поведение, и автоматически создает несовместимость с новыми уровнями API. Debug Mode — это диагностический инструмент. В режиме отладки тестеры CMAS могут выявлять и решать технические проблемы с системами CMAS и конечными устройствами. Тестировщики могут использовать код доступа для включения режима отладки на определенных конечных устройствах. Эту функцию должны использовать только тестировщики, которые обучены этому.
