从网上找了好多信息，基于安卓完整的tcp连接的各种处理没有完整的案例，基于业务开发，必须用到tcp，并需要稳定的连接，开发并做了大量的测试与优化工作，希望能帮到有同样需求的人！！！
好了，废话不多说，直接上代码！！
第一步：依赖netty-all-4.0.23.Final
第二步：初始化netty
public NettyClientBootstrap(Context context, String[] actions, int port, String host) {
this.actions = actions;
this.context = context;
this.port = port;
this.host = host;
//初始化连接
eventLoopGroup = new NioEventLoopGroup();
bootstrap = new Bootstrap();
bootstrap.channel(NioSocketChannel.class);
bootstrap.option(ChannelOption.SO_KEEPALIVE, true);
bootstrap.option(ChannelOption.RCVBUF_ALLOCATOR, new AdaptiveRecvByteBufAllocator(1024, 1024 * 32, 1024 * 64));
bootstrap.group(eventLoopGroup);
bootstrap.remoteAddress(host, port);
bootstrap.handler(new ChannelInitializer<SocketChannel>() {
@Override
protected void initChannel(SocketChannel socketChannel) throws Exception {
socketChannel.pipeline().addLast(new IdleStateHandler(20, 10, 0));
socketChannel.pipeline().addLast( new NettyClientHandler());
}
});
}
第三步：连接netty
/**
* first init tcp connect
*/
private ChannelFuture future = null;
public void start() {
LogUtil.printError("tcp", "connecing---------" + host + port);
try {
future = bootstrap.connect(new InetSocketAddress(host, port)).sync();
if (future.isSuccess()) {
socketChannel = (SocketChannel) future.channel();
return;
} else {
LogUtil.printError("tcp", "TcpUnConnect------" + "future is unConnect");
}
} catch (Exception e) {
LogUtil.printError("tcp", "TcpUnConnect------" + e.toString());
}
}第四步：发送Tcp消息：
/**
* send tcp msg
* @param msg
*/
public void startNetty(final TCPData msg) {
ThreadPoolProxy.getInstance(5, 5, 12 * 1000).executeTask(new Runnable() {
@Override
public void run() {
if (isConnect) {
socketChannel.writeAndFlush(msg);
}
}
});
}其他：关于Tcp监听部分代码：
public class NettyClientHandler extends SimpleChannelInboundHandler<Object> {
//利用写空闲发送心跳检测消息
@Override
public void userEventTriggered(ChannelHandlerContext ctx, Object evt) throws Exception {
if (evt instanceof IdleStateEvent) {
IdleStateEvent e = (IdleStateEvent) evt;
switch (e.state()) {
case WRITER_IDLE:
}
}
}
//这里是接受服务端发送过来的消息
protected void channelRead0(ChannelHandlerContext channelHandlerContext, Object baseMsg) throws Exception {
String msgObj = (String) baseMsg;
}
//这里是断线要进行的操作
@Override
public void channelInactive(ChannelHandlerContext ctx) throws Exception {
super.channelInactive(ctx);
}
//这里是出现异常的话要进行的操作
@Override
public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
super.exceptionCaught(ctx, cause);
;
}
}其实通过以上部分基本上就已经可以完成大部分tcp处理
