get instant notification when a client disconnect from server socket in android

Hai friends i am new in Socket.
Now I implement a Chat app using Socket. I am testing with single Server SA and Client CA and CB. The Socket connection, chat and disconnect are working good.
But my problem is when client(CA) disconnect from server socket server not getting instant notification. Once CA reconnect again with new name CAA server will notify CA removed, and CAA connected.
my point is server must get instant notification when client CA disconnect socket.
This is my server Activity:
public class ServerMain extends ActionBarActivity {
static final int SocketServerPORT = 8080;
TextView infoIp, infoPort, chatMsg;
String msgLog = "";
List<ChatClient> userList;
ServerSocket serverSocket;

chatServerThread.start();

using of long touch and multi thread programming

I have a problem in using of long touch and multi thread programming.
I have 2 button: up and down. Each of these buttons have OnTouchListener event habdler . When I touch down in each of them, a thread will run inside them in the while(HelperClass.Universal_IsTouch == true) and in every 1000 milisec run again until tuouch up raised and "HelperClass.Universal_IsTouch" make false in touch up and it exit from the while .
in the while loop a thrad run and call another class method for sending data via run another thread via socket programming . So then when up button (or down) touched down long time , data should be send to server until touched up raised.
Its working but after many sending up and down when I touch long up (or down) its sended data related to other routin instead main routin ?
this is my UP routin code :
//////////// up
btn_UP_var.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View arg0, MotionEvent arg1) {
IntruptedAllThread();
// TODO Auto-generated method s tub
if (arg1.getAction() == MotionEvent.ACTION_DOWN)
{
HelperClass.Universal_IsTouch = true;
} else if (arg1.getAction() == MotionEvent.ACTION_UP) {
HelperClass.Universal_IsTouch = false;
}
//Send a simple Move (once)
if (chkbx_AutoMove_var.isChecked()) {
Img_Stop_var.setImageResource(R.drawable.arrow_stop_play);
Is_UP_buttonTouched = 1;
HelperClass.Is_Stop_Button_Disable = false;
} else {
HelperClass.Is_Stop_Button_Disable = true;
thread_UP = new Thread(new Runnable() {
#Override
public void run() {
while (HelperClass.Universal_IsTouch == true) {
Cursor ListHoist = mDbHelper.GetallSelectedHoistData();
//mDbHelper.close();
for (ListHoist.moveToFirst(); !ListHoist.isAfterLast(); ListHoist.moveToNext()) {
String IP = ListHoist.getString(ListHoist.getColumnIndex("HoistIP"));
int PK_hoist = ListHoist.getInt(ListHoist.getColumnIndex("PK_hoist"));
HelperClass.SendDataToMICRO(mDbHelper, PK_hoist, IP, HelperClass.Selector_Move_Stop,
HelperClass.MoveDesition_Up, HelperClass.inutile, HelperClass.inutile,
HelperClass.inutile);
}
ListHoist.close();
try {
Thread.sleep(1000);
}
catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
IntruptedAllThread();
}
}
// thread_UP.interrupt();
IntruptedAllThread();
}
});
thread_UP.start();
}
return true;
}
});
and this is my Down Code :
//////////// Down
btn_Down_var.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View arg0, MotionEvent arg1) {
// TODO Auto-generated method stub
IntruptedAllThread();
if (arg1.getAction() == MotionEvent.ACTION_DOWN)
{
HelperClass.Universal_IsTouch = true;
//txt_MovementValue_var.setText("1");
} else if (arg1.getAction() == MotionEvent.ACTION_UP)
{
HelperClass.Universal_IsTouch = false;
//txt_MovementValue_var.setText("0");
}
//Send a simple Move (once)
if (chkbx_AutoMove_var.isChecked()) {
Img_Stop_var.setImageResource(R.drawable.arrow_stop_play);
Is_UP_buttonTouched = 0;
HelperClass.Is_Stop_Button_Disable = false;
} else {
HelperClass.Is_Stop_Button_Disable = true;
thread_Down = new Thread(new Runnable() {
#Override

HelperClass.SendDataToMICRO(mDbHelper, PK_hoist, IP, HelperClass.Selector_Move_Stop,

An error upon audio recording on Android

My application starts a thread A to save some data. In this thread I call the function startRecording(audioFile.getAbsolutePath());
But I get the following error:
start called in an invalid state: 16; at android.media.MediaRecorder.start(Native Method)
This error does not occur everytime, but sometimes I get this error report from my application.
Below, there's my code.
public void startRecording(String outputPath) {
if (recorder == null) {
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);

recorder.setAudioSamplingRate(RECORDER_SAMPLERATE_22050);
recorder.setOutputFile(outputPath);
try {
recorder.prepare();
} catch (IOException e) {
e.printStackTrace();
}
}
recorder.start();
SampleRecordThread thread = new SampleRecordThread(outputPath);
thread.start();
}
private class SampleRecordThread extends Thread {

recorder.stop();
recorder.reset();
recorder.release();
recorder = null;
// upload the data to cloud

Android UI from other thread

I'm creating an application that gets the get the homestatus from a server in json but this happens on another thread. this isn't a problem when i try to set most Items on the ui because i can set them in a static void. but when i try to create a new switch and space i can't call 'this' to create a new.
code for getting the homestatus:
public void loadHomeStatus()
{
if(socket != null) {`enter code here`
if (socket.isConnected()) {
Log.d("BtnUpdate","already connected");
return;
}
}
swAlarm = (Switch) findViewById(R.id.swAlarmState);
tvTemperature = (TextView) findViewById(R.id.tvTemprateur);
tvHumidity = (TextView) findViewById(R.id.tvHumidity);
llDevices = (LinearLayout) findViewById(R.id.llDevices);
new Thread() {
public void run() {
try
{
busyConnecting = true;
Log.d("loadHomeStatus","trying to connect to: " + host + ":" + port);
socket = new Socket(host, port);
uiConnected();
Log.d("loadHomeStatus","Connected");
DataOutputStream os = new DataOutputStream(socket.getOutputStream());
DataInputStream is = new DataInputStream(socket.getInputStream());
os.writeBytes(password);
Log.d("Connect", "send: " + password);
while (socket.isConnected()) {
byte[] data = new byte[500];
int count = is.read(data);
String recieved = new String(data).trim();
Log.d("loadHomeStatus","recieved " + recieved );
if(recieved.toLowerCase() == "failed")
{
Log.d("loadHomeStatus","failed to log in");
}
else
{
try
{
homeStatus = new Gson().fromJson(recieved, HomeStatus.class);
uiLoadStatus();
} catch (Exception e)
{
Log.d("Error", e.toString());
}
}
}//end of while loop
Log.w("loadHomeStatus", "end connection thread ");
//ends thread
Thread.currentThread().interrupt();
return;
}
catch (UnknownHostException e)
{
e.printStackTrace();
Log.w("loadHomeStatus", "no Failed to connect: " + host + "-" + 8001);
}
catch (IOException e)
{
e.printStackTrace();
Log.w("loadHomeStatus", "no Failed to connect: " + host + "-" + 8001);
}
Log.w("loadHomeStatus","Connection ended");
socket = null;
busyConnecting = false;
uiDisconnected();
}
}.start();
}`
Code for setting ui
public static void uiLoadStatus()
{
if (homeStatus != null)
{
try {
tvTemperature.post(new Runnable()
{
public void run()
{
//Log.d("uiLoadStatus to string",homeStatus.toString());
tvTemperature.setText(homeStatus.temperature + "°C");
tvHumidity.setText(homeStatus.humidity + "%");
}
});
}
catch(Exception e)
{
Log.d("uiLoadStatus status fragment", e.toString());
}
try {
swAlarm.post(new Runnable()
{
public void run() {
swAlarm.setChecked(homeStatus.alarmState);
}
});
}
catch (Exception e)
{
Log.d("uiLoadStatus alarm fragment", e.toString());
}
}
try {
llDevices.post(new Runnable()
{
public void run() {
uiLoadDevices(); //this gives and error because it's not static
}
});
}
catch (Exception e)
{
Log.d("uiLoadStatus alarm fragment", e.toString());
}
}
public void uiLoadDevices()
{
for (int i = 0; i < homeStatus.lstDevices.size(); i++) {
String deviceAdd = homeStatus.lstDevices.get(i);
Space mySpace = new Space(this);
Switch mySwitch = new Switch(this);
mySpace.setMinimumHeight(50);
mySwitch.setText(homeStatus.getName(deviceAdd));
mySwitch.setChecked(homeStatus.getState(deviceAdd));
mySwitch.setTextSize(18);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
lp.gravity = Gravity.LEFT;
llDevices.addView(mySpace, lp);
llDevices.addView(mySwitch, lp);
}
}

You should use AsyncTask and put the network interaction part in the doInBackground() method. To update the UI components, implement those logics in the onPostExecute() method

uiLoadStatus is a static method (not sure why or if it has to be without looking at all of your code) and therefore you cannot call non-static methods from within it, such as uiLoadDevices
I would advise taking a look at your code and update your uiLoadStatus to not be static if at all possible. Abusing static can lead to sloppy code.
