Question

日志行＆＃34;测试＆＃34;永远不会打印。谁能明白为什么？＆＃34;连接＆＃34;是要打印的最后一行。

这是在Android 8（26）和Netty 4.1.18.Final

上完成的

我有这段代码：

        Bootstrap b = new Bootstrap();
        group = new NioEventLoopGroup();
        Log.d(RegisterAttemptTcp.class.getName(), "connecting");
        InetSocketAddress ria = new InetSocketAddress(toHostname, portDestination);
        b.group(group).channel(NioSocketChannel.class).option(ChannelOption.IP_TOS, 24)
                .remoteAddress(ria).handler(new ChannelInitializer<SocketChannel>() {
                    @Override
                    protected void initChannel(SocketChannel ch) throws Exception {
                        ch.pipeline().addLast(new SimpleHandlerTest());
                    }
                });
        b.localAddress(portAttempt);

         ChannelFuture future = b.connect().sync();
        future.channel().closeFuture().await(8_000);

和

public class SimpleHandlerTest extends SimpleChannelInboundHandler<ByteBuf> {
    @Override
    protected void channelRead0(ChannelHandlerContext ctx, ByteBuf msg) throws Exception {

    }

    @Override
    public void channelActive(ChannelHandlerContext ctx) throws Exception {
        super.channelActive(ctx);
        Log.d(SimpleHandlerTest.class.getName(), "Testing");
    }
}

似乎您的连接尝试未完成（无论出于何种原因）。默认情况下，netty应在10秒后以超时异常失败连接操作的Future。

Netty 4和android 26
