Como funciona o Push Kit da Huawei

Olá, Habr! Em maio do ano passado, sem os serviços e APIs do Google, começamos a trabalhar em nossa plataforma Huawei Mobile Services . Este é o nosso projeto de longa data, ao qual voltamos após a imposição das sanções americanas. O problema do "corte" dos serviços foi desaparecendo gradualmente. Adicionamos componentes que faltam: um cliente de e-mail, nossos próprios mapas e outros serviços, e HMS Core - um conjunto de APIs, SDKs e outros serviços para desenvolver e melhorar aplicativos. Este conjunto inclui o Push Kit - um serviço de notificação baseado em nuvem - e muito mais. Abaixo do corte, mostraremos como essa ferramenta funciona, como ela se destaca e como pode ser usada.

A principal função do Push Kit (falaremos sobre o resto mais tarde) é entregar notificações de aplicativos para o dispositivo do usuário. Este processo é organizado assim:
