Developing a chat or message app requires lots of skills, including server’s back-end service creation skill and Android development skill. It is better for a developer to let a 3rd-party handle server logic and scalability to focus on Android development only.
There are many services which provides back-end for message storage while providing API & SDK for developer to create a message app easier.
What these services offer:
- Server for messages storage
- SDKs for app development
- Push notification support
- One-to-one, group and cross-platform chat support
