Preface:
Recently, the company plans to first learn android technology, and then recruit Andirod, which is quite expensive. The boss wants me to do it, so I will do it, and by the way, make some summaries, and quickly start android strategy from Java background transformation.
Andoird website address developer. The android. Google. Cn /
Step 1 Create a project
- Address: document cloud.tencent.com/product/im
2. Download the SDK from the documentation and make an integration
- Address: document cloud.tencent.com/document/pr…
3. Present an integrated demo
- The functions include login, logout, create a group Create a single callback, create a group callback, send a message, receive parse messages, network send messages
- Address: download.csdn.net/download/we…

Copy the code4.1 introduction
- The functions include login, logout, create a group Create a single callback, create a group callback, send a message, receive parse messages, network send messages
- This is achieved by integrating SDK
- And then call the method
- There was an unsuccessful attempt to get the group call, and it was ok to generate the Usersgin implementation with a new SDkappID
- ok
