how do I make the service start automatically after restarting the phone?

[NerdyCrow]

After restarting the phone, the service does not start automatically. You need to log in to the application, only after that it will start AndroidManifest.xml `

<application
    android:label="background_service"

Good day!

Will there be a solution to this problem or some workarounds?
