no data is added to list of integer in android

I have json data from webservice that should be stored in two lists, String list and Integer List. the one for strings stores the data fine but the one for the integers doesn't. it prompts error saying java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

hope I get right answer
thanks in advance

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
means that your Array is empty and you are trying to access array element from an empty array.
You can put a condition to check if array length is more than 0 and then proceed using it like:
if(array != null && array.length > 0){
// do parsing
}

Make sure your class School contains variable with name pK_ID. Look carefully on the upper/lower cases in the variable name.
If the variable name is not matching with JSON tag then this will result in empty fetching from JSON, even if you are getting valid JSON from URL as per your comment.

Android send received data from a socket service to Activity

I am looking for a way to send received data (receive while flag is set) from a socket service to an activity that is bound to the service. What is the best way to do this ? Handlers , AsyncTask or something else ?
this is the SocketClass I am using to start a connection and handle the incoming messages :
class connectSocket implements Runnable {
#Override
public void run() {
running= true;
try {
socket = new Socket(serverAddr, SERVERPORT);
try {
mBufferOut = new ObjectOutputStream(socket.getOutputStream());
mBufferIn = new ObjectInputStream(socket.getInputStream());
while(running){
msg = (Message) mBufferIn.readObject();
}
}
catch (Exception e) {
Log.e("TCP", "S: Error", e);
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
}
Update :
public class SocketService extends Service {
private static final String TAG = "com.oos.kiesa.chat";
public static final String SERVERIP = "192.168.X.X";
public static final int SERVERPORT = 4444;
private ObjectOutputStream mBufferOut;
private ObjectInputStream mBufferIn;
Socket socket;
InetAddress serverAddr;
boolean mRun;
Object msg;
public Integer command;
#Override
public IBinder onBind(Intent intent) {
return myBinder;
}
private final IBinder myBinder = new LocalBinder();
public class LocalBinder extends Binder {
public SocketService getService() {
return SocketService.this;
}
}
#Override
public void onCreate() {
super.onCreate();
}
public void IsBoundable(){
Toast.makeText(this,"is boundable", Toast.LENGTH_LONG).show();
}
public void sendMessage(String message) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeObject(message);
mBufferOut.flush();
}
}
public void sendMessage(Message message) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeObject(message);
mBufferOut.flush();
}
}
public void sendMessage(User user) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeObject(user);
mBufferOut.flush();
}
}
public void sendMessage(int command) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeInt(command);
mBufferOut.flush();
}
}
#Override
public int onStartCommand(Intent intent,int flags, int startId){
super.onStartCommand(intent, flags, startId);
System.out.println("I am in on start");
Runnable connect = new connectSocket();
new Thread(connect).start();
return START_STICKY;
}
public void stopClient() throws IOException{
if (mBufferOut != null) {
mBufferOut.flush();
mBufferOut.close();
}
mBufferIn = null;
mBufferOut = null;
socket.close();
}
class connectSocket implements Runnable {
#Override
public void run() {
mRun = true;
try {
socket = new Socket(serverAddr, SERVERPORT);
try {
mBufferOut = new ObjectOutputStream(socket.getOutputStream());
mBufferIn = new ObjectInputStream(socket.getInputStream());
while(mRun){
switch(command.intValue()){
case Constants.ADD_MESSAGE:
msg = (Message) mBufferIn.readObject(); // send message to Activity
break;
}
}
}
catch (Exception e) {
Log.e("TCP", "S: Error", e);
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
}
#Override
public void onDestroy() {
super.onDestroy();
try {
socket.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
socket = null;
}
}
Some guidance / examples would be greatly appreciated

I am sending you mine, hope it will help :

clientSocketInputStream = new DataInputStream(clientSocekt.getInputStream());
while (true) {
bytes = new byte[1024];
clientSocketInputStream.read(bytes);
bytes = trim(bytes);
if (bytes.length > 0 && !doSkip) {
String newString = new String(bytes, "UTF-8");
String decoded = pingStr + newString;
pingStr = checkForMessage(decoded);
responseStringComplete += newString;

closeStreams();
} catch (UnknownHostException e) {
e.printStackTrace();

To broadcast chat data just do :
msg = (Message) mBufferIn.readObject(); // Do code after this line
Intent localIntent = new Intent("CHAT_MESSAGE");
localIntent.putExtra("message", msg);
LocalBroadcastManager.getInstance(context).sendBroadcast(localIntent);
Now in the activity where you are showing the chat list you can do
class ReceiveMessages extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (action.equals("CHAT_MESSAGE")) {
runOnUiThread(new Runnable() {
#Override
public void run() {
String chatMessage = getIntent().getStringExtra("message");
//get data from intent and update your chat list.
}
});
}
}
}
ReceiveMessages myReceiver;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//your code
myReceiver = new ReceiveMessages();
}
#Override
protected void onStart() {
super.onStart();
LocalBroadcastManager.getInstance(this).registerReceiver(myReceiver,
new IntentFilter("CHAT_MESSAGE"));
}
#Override
protected void onStop() {
super.onStop();
LocalBroadcastManager.getInstance(this).unregisterReceiver(myReceiver);
}

Sending and Receiving messages using Smack Api for Android

I'm trying since last four days to send and receive chat message using own XMPP and with Smack+OpenFire. According to Smack's "readme.txt' i set up the connection and got logged user in. The code of connection and login is this
public static String TAG = "Test connection";
private static XMPPTCPConnection connection;
private static String userName = "demo";
private static String Password = "demo";
static {
// Create the configuration for this new connection
XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled);
configBuilder.setResource("");
configBuilder.setUsernameAndPassword(userName, Password);
configBuilder.setServiceName("192.168.2.10");
configBuilder.setHost("192.168.2.10");
configBuilder.setPort(5222);
configBuilder.setCompressionEnabled(false);
connection = new XMPPTCPConnection(configBuilder.build());
}
This way i configured the connectionbuilder.
here i am connecting and signing in the user.
public class ConnectAndLogin extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... params) {
try {
connection.connect();
Log.i(TAG, "Connected to " + connection.getHost());
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
Log.e(TAG, "Failed to connect to " + connection.getHost());
Log.e(TAG, e.toString());
e.printStackTrace();
}
try {
connection.login(userName, Password);
Log.i(TAG, "Login as a : " + connection.getUser());
setConnection(connection);
setListner();
} catch (XMPPException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
} catch (SmackException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
} catch (IOException e) {
e.printStackTrace();
Log.i(TAG, "Login error " + e.toString());
}
return null;
}
}
In some tutorials that the addPacketListner must be set after login. i done that in setConnection() and some posts went through addAsyncStanzaListner.
for send message
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Message msg = new Message("demo2", Message.Type.chat);
msg.setBody("Hi how are you");
if (connection != null) {
try {
connection.sendPacket(msg);
Log.d("Send to room : Name : ", "demo2");
Log.d("store", "store data to db");
//DBAdapter.addUserData(new UserData(text, "", "1" ,beam_id));
} catch (Exception e) {
Log.d("ooo", "msg exception" + e.getMessage());
}
}
}
});
and for receiving messages this code
public void setListner() {
connection.addAsyncStanzaListener(new StanzaListener() {
#Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
Message message = (Message) packet;
Log.i(TAG, "REC : " + message.getBody());
Log.i(TAG, "REC: " + message.getFrom());
}
}, new StanzaFilter() {
#Override
public boolean accept(Stanza stanza) {
return false;
}
});
}
here is my dependencies
compile 'org.igniterealtime.smack:smack-android:4.1.0'
compile 'org.igniterealtime.smack:smack-tcp:4.1.0'
compile 'org.igniterealtime.smack:smack-core:4.1.0'
compile 'org.igniterealtime.smack:smack-im:4.1.0'
compile 'org.igniterealtime.smack:smack-resolver-minidns:4.1.0'
compile 'org.igniterealtime.smack:smack-sasl-provided:4.1.0'
But still i'm not able to send messages to demo2 user.
Where im doing wrong.Please guide and help me.
Thanks

How to view the Intents a BroadcastReceiver is receiving?

I have an infinite loop somewhere in my code, indicative of my group messaging BroadcastReceiver continually accepting only the first message in the database, over and over again, until I stop running the application. Note that the repeating of the message only occurs in the client app and not in the server database.
Is there way to trace what intent the BroadcastReceiver is receiving? ie. be able to view the intents the BroadcastReceiver is acting on to locate the source of these actions?
My code for both sending and receiving a group message if it helps: (BroadcastReceiver is near the bottom)

How to get friends info that requires permission like B'day using facebook graph api

I'm having android Button for Login.
below is the onclick listener of that button.
btnLoginFB.setOnClickListener(new View.OnClickListener() {
#
Override
public void onClick(View v) {
Session s = new Session(Startup.this);
Session.setActiveSession(s);
Session.OpenRequest request = new Session.OpenRequest(Startup.this);
List < String > permissions = new ArrayList < String > ();
permissions.add("friends_birthday");
permissions.add("friends_location");
request.setPermissions(permissions);
request.setCallback(new Session.StatusCallback() {
#
Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
Request.newMyFriendsRequest(Session.getActiveSession(), new Request.GraphUserListCallback() {
#
Override
public void onCompleted(List < GraphUser > users, Response response) {
if (users != null) {
for (int i = 0; i < users.size(); i++) {
String frndLoc = "empty";
try {
users.get(i).getLocation().getProperty("name");
frndLoc = "" + users.get(i).getLocation().getProperty("name");
} catch (Exception e) {}
Toast.makeText(Startup.this, users.get(i).getBirthday() + " - " +
users.get(i).getName() + "\n" +
frndLoc, Toast.LENGTH_LONG).show();
}
}
}
}).executeAsync();
} // end of if (session.isOpened())
} // end of call
});
s.openForRead(request);
}
});
The problem is I'm getting null for both B'day and Location of friend.

Request friendRequest = Request.newMyFriendsRequest(activeSession, new GraphUserListCallback() {
#Override
public void onCompleted(final List<GraphUser> users, Response response) {
ArrayList<String> o = new ArrayList<String>();
for (GraphUser u : users) {
o.add(u.getInnerJSONObject().toString());
}
getSherlockActivity().startService(
new Intent(getSherlockActivity(), InsertInDBService.class).putExtra("fbdata", o));
}
}
});
Parse the reponse
int count = users.size();
for (int i = 0; i < count; i++) {
String name = "", id = "", photoUrl = "";
String birthday = "", location = "";
String website = "";
JSONObject o = null;
try {
o = new JSONObject(users.get(i));
} catch (JSONException e) {
}
try {
id = o.getString("id");
name = o.getString("name");
photoUrl = o.getJSONObject("picture").getJSONObject("data").getString("url");
} catch (JSONException e) {
e.printStackTrace();
dbFacebookMain.deleteFACEBOOK();
}
try {
location = o.getJSONObject("location").getString("name");
} catch (JSONException e) {
}
try {
birthday = o.getString("birthday");
} catch (JSONException e) {
}
try {
website = o.getString("website");
} catch (JSONException e) {
}
