Тази кодова база в блога, който споменахте, използвах в едно от моите приложения, които разработвам. Това ще покаже известие при получаване на ново известие и ще отвори нова дейност, когато потребителят щракне върху известието.
Винаги изпращай не изпращай всички данни чрез насочено известие. просто изпращате малко съобщение като данни, след което изтегляте данните от сървъра, след като съобщението е получено във вашето устройство, след това го съхранявайте в db.
