昨天我試圖創建一個android應用程序和一個Windows應用程序。C＃客戶端 - Java服務器數據讀取速度慢？ - 已解決
Android應用 - 發送的炭[]使用WIFI的窗口應用程序的一對。
的Windows應用程序 - C＃服務器應用程序，監聽客戶端的數據
不過這兩個程序運作良好，但數據從服務器讀取是有點很慢。
我發送的是這樣的信息。我有一個手柄通過otg連接到我的手機，當我按下按鈕A數據變成這樣。我甚至嘗試在我的android應用程序中放置一個textview，它沒有任何延遲地工作，當我按下按鈕時，我可以看到我的textview中更改的數據集。
所以我認爲問題是在服務器和客戶端之間。這是不可能解決的，因爲它們是2個不同的平臺？我已經嘗試過這種東西，Xamarin，它運行良好。但由於某些具體原因，我不想在這一點上使用Xamarin。
比方說，我按下按鈕A，B，C，d這樣的數據是這樣的，我清楚地可以看到它在Android應用TextView的，當然，我會在我的服務器程序看到這個數據，但只有在大約10-30秒的延遲之後。
我的手機是Nexus 5.這是使用兩種不同平臺的結果嗎？
服務器代碼： -
private void startBtn_Click(object sender, EventArgs e)
{
Thread thread = new Thread(new ThreadStart(StartServer));
thread.Start();
}
void StartServer()
{
Log("Running");
TcpClient client = new TcpClient();
TcpListener server = new TcpListener(IPAddress.Any, 8888);
server.Start();
client = server.AcceptTcpClient();
Log("Client connected");
byte[] byteArray = new byte[8];
NetworkStream inOpt = client.GetStream();
while (true)
{
inOpt.Read(byteArray, 0, 8);
Log(ASCIIEncoding.);
}
}
void Log(string msg)
{
if (InvokeRequired)
{
this.Invoke(new Action<string>(Log), new object[] {msg});
return;
}
logBox.Text = "";
logBox.Text += msg + Environment.NewLine;
}
Android客戶端代碼： -
char[] keys = {'0', '0', '0', '0', '0', '0', '0', '0'};
TextView textView;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList gameControllerDeviceIds = new ArrayList();
int[] deviceIds = InputDevice.getDeviceIds();
for (int deviceId : deviceIds) {
InputDevice dev = InputDevice.getDevice(deviceId);
int sources = dev.getSources();
// Verify that the device has gamepad buttons, control sticks, or both.
if (((sources & InputDevice.SOURCE_GAMEPAD) == InputDevice.SOURCE_GAMEPAD)
|| ((sources & InputDevice.SOURCE_JOYSTICK)
== InputDevice.SOURCE_JOYSTICK)) {
// This device is a game controller. Store its device ID.
if (!gameControllerDeviceIds.contains(deviceId)) {
gameControllerDeviceIds.add(deviceId);
Log.d("yolol", String.valueOf(deviceId));
}
}
}
//Log.d("yolol", InputDevice.getDevice(7).getName());
new CheckUsageStartup().execute();
Log.d("sss", Arrays.toString(keys));
textView = (TextView) findViewById(R.id.textView);
}
byte[] toByteArray(String[] strong){
ByteArrayOutputStream baos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(baos);

return baos.toByteArray();

下面的代碼。請告訴我可能的解決方案。它編碼是否做了這麼多的延遲，也許呢？
