android之socket用戶端

標籤：

接收資料不要用readline(),用read()

Socket mSocket = new Socket("192.168.1.100", 8888);

DataInputStream dinput = new DataInputStream(mSocket.getInputStream())

讀取服務端發過來的資料：

int length = dinput.read(bbuf);
String mStrMSG = new String(bbuf, 0, length, "gb2312");

TCP服務端

使用執行個體化即可

try
{
tcpclient =new TCPClient();
tcpclient.StartTCPClient();
} catch (Exception e)
{
// TODO: handle exception
Log.e("MainActivity", e.toString());
}
