# DeviceUDPManager 使用说明 |
|||
|
|||
## 概述 |
|||
`DeviceUDPManager` 是基于 KryoNet 库实现的 UDP 通信管理器,支持客户端和服务端两种模式,提供了完整的 UDP 数据收发功能。 |
|||
|
|||
## 特性 |
|||
- ✅ 支持客户端和服务端模式 |
|||
- ✅ 自动重连机制 |
|||
- ✅ 线程安全的数据收发 |
|||
- ✅ 支持多种数据类型(String、Integer、byte[]等) |
|||
- ✅ 完整的事件回调机制 |
|||
- ✅ 单例模式,全局统一管理 |
|||
|
|||
## 快速开始 |
|||
|
|||
### 1. 依赖已添加 |
|||
在 `app/build.gradle` 中已添加必要依赖: |
|||
```gradle |
|||
// KryoNet UDP通信库 |
|||
implementation 'com.esotericsoftware:kryonet:2.22.0-RC1' |
|||
implementation 'com.esotericsoftware:kryo:2.24.0' |
|||
``` |
|||
|
|||
### 2. 权限配置 |
|||
在 `AndroidManifest.xml` 中已包含必要权限: |
|||
```xml |
|||
<uses-permission android:name="android.permission.INTERNET" /> |
|||
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> |
|||
``` |
|||
|
|||
### 3. 基本使用 |
|||
|
|||
#### 客户端模式 |
|||
```java |
|||
// 获取管理器实例 |
|||
DeviceUDPManager udpManager = DeviceUDPManager.getInstance(); |
|||
|
|||
// 设置监听器 |
|||
udpManager.setMessageListener(new DeviceUDPManager.UDPMessageListener() { |
|||
@Override |
|||
public void onMessageReceived(Object message, Connection connection) { |
|||
Log.i("UDP", "收到消息: " + message); |
|||
} |
|||
|
|||
@Override |
|||
public void onMessageSent(Object message) { |
|||
Log.i("UDP", "发送成功: " + message); |
|||
} |
|||
|
|||
@Override |
|||
public void onMessageSendFailed(Object message, String error) { |
|||
Log.e("UDP", "发送失败: " + error); |
|||
} |
|||
}); |
|||
|
|||
udpManager.setConnectionStateListener(new DeviceUDPManager.ConnectionStateListener() { |
|||
@Override |
|||
public void onConnected() { |
|||
Log.i("UDP", "连接成功"); |
|||
// 可以开始发送消息 |
|||
udpManager.sendUDPMessage("Hello Server!"); |
|||
} |
|||
|
|||
@Override |
|||
public void onDisconnected() { |
|||
Log.i("UDP", "连接断开"); |
|||
} |
|||
|
|||
@Override |
|||
public void onConnectionFailed(String error) { |
|||
Log.e("UDP", "连接失败: " + error); |
|||
} |
|||
|
|||
@Override |
|||
public void onReconnecting(int attempt) { |
|||
Log.i("UDP", "重连中,第 " + attempt + " 次"); |
|||
} |
|||
}); |
|||
|
|||
// 初始化为客户端 |
|||
udpManager.initializeAsClient(context, "192.168.1.100", 54555, 54777); |
|||
``` |
|||
|
|||
#### 服务端模式 |
|||
```java |
|||
// 获取管理器实例 |
|||
DeviceUDPManager udpManager = DeviceUDPManager.getInstance(); |
|||
|
|||
// 设置监听器(同客户端) |
|||
// ... |
|||
|
|||
// 初始化为服务端 |
|||
udpManager.initializeAsServer(context, 54555, 54777); |
|||
``` |
|||
|
|||
### 4. 发送消息 |
|||
```java |
|||
// 发送字符串消息 |
|||
udpManager.sendUDPMessage("Hello UDP!"); |
|||
|
|||
// 发送数字消息 |
|||
udpManager.sendUDPMessage(12345); |
|||
|
|||
// 发送JSON格式消息 |
|||
String jsonMsg = "{\"type\":\"status\",\"value\":\"online\"}"; |
|||
udpManager.sendUDPMessage(jsonMsg); |
|||
|
|||
// 服务端模式:发送消息给特定客户端 |
|||
udpManager.sendUDPMessageToConnection(connection, "Hello Client!"); |
|||
``` |
|||
|
|||
## API 参考 |
|||
|
|||
### 主要方法 |
|||
|
|||
#### 初始化方法 |
|||
- `initializeAsClient(Context, String, int, int)` - 初始化为客户端 |
|||
- `initializeAsServer(Context, int, int)` - 初始化为服务端 |
|||
|
|||
#### 消息发送 |
|||
- `sendUDPMessage(Object)` - 发送UDP消息 |
|||
- `sendUDPMessageToConnection(Connection, Object)` - 发送消息给特定连接(服务端模式) |
|||
|
|||
#### 状态管理 |
|||
- `isConnected()` - 获取连接状态 |
|||
- `isInitialized()` - 获取初始化状态 |
|||
- `isClientMode()` - 获取当前模式 |
|||
- `reconnect()` - 手动重连(客户端模式) |
|||
- `stop()` - 停止UDP管理器 |
|||
- `release()` - 释放所有资源 |
|||
|
|||
#### 配置方法 |
|||
- `setMessageListener(UDPMessageListener)` - 设置消息监听器 |
|||
- `setConnectionStateListener(ConnectionStateListener)` - 设置连接状态监听器 |
|||
- `setAutoReconnect(boolean)` - 设置自动重连 |
|||
|
|||
### 回调接口 |
|||
|
|||
#### UDPMessageListener |
|||
- `onMessageReceived(Object, Connection)` - 接收到消息 |
|||
- `onMessageSent(Object)` - 消息发送成功 |
|||
- `onMessageSendFailed(Object, String)` - 消息发送失败 |
|||
|
|||
#### ConnectionStateListener |
|||
- `onConnected()` - 连接成功 |
|||
- `onDisconnected()` - 连接断开 |
|||
- `onConnectionFailed(String)` - 连接失败 |
|||
- `onReconnecting(int)` - 重连中 |
|||
|
|||
## 使用场景 |
|||
|
|||
### 1. 设备间通信 |
|||
```java |
|||
// 设备A作为服务端 |
|||
udpManager.initializeAsServer(context, 54555, 54777); |
|||
|
|||
// 设备B作为客户端 |
|||
udpManager.initializeAsClient(context, "设备A的IP", 54555, 54777); |
|||
``` |
|||
|
|||
### 2. 命令控制 |
|||
```java |
|||
// 发送控制命令 |
|||
udpManager.sendUDPMessage("command:restart"); |
|||
udpManager.sendUDPMessage("command:get_status"); |
|||
|
|||
// 接收端处理 |
|||
@Override |
|||
public void onMessageReceived(Object message, Connection connection) { |
|||
if (message.toString().startsWith("command:")) { |
|||
String command = message.toString().substring(8); |
|||
handleCommand(command, connection); |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 3. 状态同步 |
|||
```java |
|||
// 定期发送状态信息 |
|||
String status = "{\"device_id\":\"" + Build.MODEL + |
|||
"\",\"status\":\"online\"," + |
|||
"\"timestamp\":" + System.currentTimeMillis() + "}"; |
|||
udpManager.sendUDPMessage(status); |
|||
``` |
|||
|
|||
## 注意事项 |
|||
|
|||
1. **线程安全**: 所有方法都是线程安全的,可以在任意线程调用 |
|||
2. **网络权限**: 确保应用具有网络访问权限 |
|||
3. **端口占用**: 避免端口冲突,确保指定端口未被其他应用使用 |
|||
4. **数据类型**: 发送的对象需要是Kryo支持的类型或已注册的自定义类型 |
|||
5. **资源释放**: 在不需要时调用 `stop()` 或 `release()` 释放资源 |
|||
6. **异常处理**: 网络操作可能失败,注意处理回调中的错误信息 |
|||
|
|||
## 测试 |
|||
|
|||
可以使用提供的 `UDPTestActivity` 进行功能测试: |
|||
|
|||
1. 在 `AndroidManifest.xml` 中注册Activity |
|||
2. 启动Activity进行测试 |
|||
3. 可以在同一设备上启动服务端和客户端进行本地测试 |
|||
|
|||
## 扩展 |
|||
|
|||
### 自定义数据类型 |
|||
```java |
|||
// 注册自定义类型 |
|||
public class CustomMessage { |
|||
public String type; |
|||
public String content; |
|||
public long timestamp; |
|||
} |
|||
|
|||
// 在初始化时注册 |
|||
udpManager.getKryo().register(CustomMessage.class); |
|||
``` |
|||
|
|||
### 加密通信 |
|||
可以在发送前加密消息,接收后解密: |
|||
```java |
|||
// 发送加密消息 |
|||
String encrypted = encrypt(originalMessage); |
|||
udpManager.sendUDPMessage(encrypted); |
|||
|
|||
// 接收解密消息 |
|||
String decrypted = decrypt(encryptedMessage); |
|||
``` |
