Background process for an application running on a smartphone with android version 6.0 or higher

Please tell me if there is an application that receives messages (including in the background (i.e. when it is closed or minimized)). On the smartphone with the version android 5.1.1, the application works fine, i.e. Messages in the background arrive, but on the android version 7.1 is not. Do you need to register a request to the user, provide the opportunity for the application to work in the background, if so how to do it (specifically permission for the application to work in the background)? If not, what could be the solutions to this problem?
