# Notification chat
ЭSo here we are in the chat! Next, here's a list of what you need to know for background notification to work! I remind you that the project will be published on Sketchub.
Here is a screenshot.
    
And now in the code that you need to pay attention, if you have a different name for the activity or icons, then change.
be sure to set the permission, otherwise it won't work.
 
we go to the manifest, where we noted and this code is needed.
 
```
android:enabled="true"
android:exported="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
```
Well, the last screen, where I noted this, is the sending of a notification.
The structure of the base is as follows.\
• When sending a notification, the following fields are created:\
° from - The UID of the sender is passed here\
° message - The message is sent here\
° read - Flag 0 or 1 is written here (0 - message not read, 1 - message read)\
P.S. If the flag is 1, then this notification will not be received, since the service will consider it read\
° title - Notification title\
° to - The UID of the recipient is transmitted here (by this field, the service will find out who the notification is assigned to)
@ l e k s from 4pda thanks!=)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://esp-ru.gitbook.io/gradient-messenger/notification-chat.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
