# NixMsg Java / Android SDK
|
||||
|
||||
坐标：`asia.asio.nixmsg:nixmsg-sdk`
|
||||
包名：`asia.asio.nixmsg`
|
||||
字节码目标：Java 8
|
||||
接口：`CompletableFuture`
|
||||
|
||||
## Android
|
||||
|
||||
最低 API **24**。MQTT 长连接由应用自行放入**前台服务**，SDK 不创建也不托管服务生命周期。
|
||||
|
||||
## 依赖
|
||||
|
||||
Maven / Gradle 仓库：
|
||||
|
||||
```
|
||||
https://git.asio.asia/api/packages/nixevol/maven
|
||||
```
|
||||
|
||||
HiveMQ MQTT Client（含 WebSocket：`webSocketConfig` + `netty-codec-http`）。
|
||||
|
||||
## 最小示例
|
||||
|
||||
```java
|
||||
Client c = new Client();
|
||||
c.onSession(token -> { /* 应用保存 */ });
|
||||
c.onMessage(msg -> System.out.println(msg.id + " " + msg.body.data));
|
||||
c.connect("ws://127.0.0.1:7443/mqtt", "device-1", "secret", null)
|
||||
.thenCompose(v -> c.send(new Types.Target("endpoint", "device-2"), new Types.Body("hello"), new Types.SendOptions()))
|
||||
.join();
|
||||
c.close();
|
||||
```
