When I run the game using unity I get this error continuously in the console window and the loading screen is not going further next. Help me to fix this issue.

The line 329 is this

The problem is coming from the last comma you are adding in the string you are adding to your PlayerPrefs in this part:
if (!PlayerPrefs.HasKey(Achievement_data_key))
{
string achi = "";
for (int i = 1; i <= 22; i++)
{
achi += i + "-1-0-0,";
}
//Debug.Log("Create new achievement " + achi);
PlayerPrefs.SetString(Achievement_data_key, achi);
}
This code generates this string:
1-1-0-0,2-1-0-0,3-1-0-0,4-1-0-0,5-1-0-0,6-1-0-0,7-1-0-0,8-1-0-0,9-1-0-0,10-1-0-0,11-1-0-0,12-1-0-0,13-1-0-0,14-1-0-0,15-1-0-0,16-1-0-0,17-1-0-0,18-1-0-0,19-1-0-0,20-1-0-0,21-1-0-0,22-1-0-0,
Keep in memory that last comma at the end of the string.
You are later doing a split on the ',' character, and iterating over them.
string[] achie = achievement.Split(',');
for (int i = 0; i< dataAchievementCache.Length; i++)
{
//Debug.Log(achie[i]);
string[] infoAchie = achie[i].Split('-');
string group = infoAchie[0];
string level = infoAchie[1];
...
}
The problem is that by doing so, your achie string array contains an empty last element. So when you are later splitting on the "-" character, your infoAchie string array only contains one element: the empty string. The first line:
string group = infoAchie[0];
Still works, but is filled with the empty string. Then:
string level = infoAchie[1];
Can't work, as you are indeed out of the bounds of the infoAchie array.
The solution would be to add the comma to your string only if it is not the last element.
Also, I strongly advise you to use a StringBuilder over a simple string for optimization purposes. Your code could then look like, for instance:
if (!PlayerPrefs.HasKey(Achievement_data_key))
{
StringBuilder achi = new StringBuilder();
for (int i = 1; i <= 22; i++)
{
achi.Append(i).Append("-1-0-0");
if(i != 22)
achi.Append(",");
}
//Debug.Log("Create new achievement " + achi);
PlayerPrefs.SetString(Achievement_data_key, achi.ToString());
}
Which generates this string:
1-1-0-0,2-1-0-0,3-1-0-0,4-1-0-0,5-1-0-0,6-1-0-0,7-1-0-0,8-1-0-0,9-1-0-0,10-1-0-0,11-1-0-0,12-1-0-0,13-1-0-0,14-1-0-0,15-1-0-0,16-1-0-0,17-1-0-0,18-1-0-0,19-1-0-0,20-1-0-0,21-1-0-0,22-1-0-0
I am using FirebaseRecyclerAdapter to display chat messages.
private void attachRecyclerViewAdapter() {

mRecyclerViewAdapter = new FirebaseRecyclerAdapter<Chat, ChatHolder>(
Chat.class, R.layout.message, ChatHolder.class, lastFifty) {
#Override
public void populateViewHolder(ChatHolder chatView, Chat chat, int position) {
chatView.setName(chat.getName());
chatView.setText(chat.getText());
chatView.setTimeLocation(chat.getTime());

if (currentUser != null && chat.getUid().equals(currentUser.getUid())) {
chatView.setIsSender(true);
} else {

}
}
};
I have a list that contains list of specific users. I would like to apply filter to see only messages from those specific users. What should I do ?
You can create messages with user id pair nodes. For example messages->'uid1-uid2'->...
To prevent which is first order uids alphatecially as the following messageId generator code does:
public static String getMessageId(String id1, String id2){
String messageId;
if(id1.compareTo(id2) < 0){
messageId = id1 + "-" + id2;
}else if(id1.compareTo(id2) > 0) {
messageId = id2 + "-" + id1;
}else{
messageId = id1;
}
return messageId;
}
When you want to see the chat history between a user and urself, obtain the user's id and generate messageId = getMessageId(id1, id2); or messageId = getMessageId(id2, id1); gives the same result since the order doesn't affect the result.
Then call the messages from the node messages -> messageId
P.S. you should restructure your messages node as i describe.
EDIT
You can convert messageId to md5 equivalent to save chars.
just change
return messageId;
to
return md5(messageId);
where md5 is:
public static String md5(final String s) {
try {
// Create MD5 Hash
MessageDigest digest = java.security.MessageDigest
.getInstance("MD5");
digest.update(s.getBytes());
byte messageDigest[] = digest.digest();
// Create Hex String
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < messageDigest.length; i++) {
String h = Integer.toHexString(0xFF & messageDigest[i]);
while (h.length() < 2)
h = "0" + h;
hexString.append(h);
}
return hexString.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return "";
}

Data are like stream bytes and can not be processed immediately when it comes with a few bytes. Data will not come all at once as a single packet. You have to use the other byte[] buffer (MainBuffer) in which you will gradually save incoming byte and move the index in that buffer. Then, from time to time (e.g. in the timer once per second) take data from the main buffer and processed it. By default you must implement some data frame with a separator (eg. Data * data * data * - Many ways to do it good or bad). I dealt with this in .net via Xamarin, but just as an example it may be helpfull :
update example, format
In ConnectedThread :

dataBundle.PutByteArray("Data", dataRead);
Message message = btlManager.sourceHandler.ObtainMessage();
message.What = 1;
message.Data = dataBundle;
btlManager.sourceHandler.SendMessage(message);
}
}
catch (System.Exception e)
{
btlManager.btlState = BTLService.BTLState.Nothing;
}
}
}
In BTLHandler :
public override void HandleMessage(Message msg)
{
switch (msg.What)
{
case 1:
{
byte[] data = msg.Data != null ? msg.Data.GetByteArray("Data") : new byte[0];
btlService.BTLReceiveData(data);
}
break;

lock (dataReadLock)
{
for (int i = 0; i < data.Length; i++)
{
dataRead[dataReadWriteCursor] = data[i];
dataReadWriteCursor++;
}

int tmpReadCursor = dataReadReadCursor;
lock (dataReadLock)
{

I can't understand what is wrong in my code . I am getting error in myAddressUniqueness. don't know why.Before i have tried it with string data type but got the same error. It is saying java.null exception.
ArrayList<String> myAddressUniqueness = null;
String name = "hello";
if (indexBody < 0 || !cursor.moveToFirst())
return;
smsList.clear();
do {
// int cursorPostion = cursor.getPosition();
String address;
String msgStr = cursor.getString(indexBody);
String senderNumber = cursor.getString(indexAddr);
Log.d("Name : ", senderNumber);
// String name = cursor.getString(cursor
// .getColumnIndex(PhoneLookup.DISPLAY_NAME));
// Log.d("Name : ",name);
if (name != null) {
address = name;
} else {
address = senderNumber;
}
Log.d("Address: ", address);
flag = 1;
//Log.e("Number: ", addressUniqueness.length + "");
for (j = 0; j < myAddressUniqueness.size(); j++) {
if (myAddressUniqueness.contains(address)) {
flag = 0;
break;
}
}
if (flag == 1) {
myAddressUniqueness.add(new String(address));
i++;
String str = "Sender: " + address + "\n";
smsList.add(str);
}
// TODO Auto-generated catch block
} while (cursor.moveToNext());
Change your declaration to
ArrayList<String> myAddressUniqueness = new ArrayList<String>();
You have it initialized to null. This will instantiate it then you can add data to it.
You should instantiate myAddressUniqueness by myAddressUniqueness = new ArrayList<String>() before using it.
I can receive my mails from Gmail Server and show theme on a listview on my Android Project. Yesterday, I started to change my mail's imageview for "unread" or "read" situation. But, then I realized that when my application connected to Gmail Server and receiving my mails, the RECENT mails become SEEN mails. And because of this reason I can't set my imageview's for unread mails.
I mean; I want to receive my mails from Gmail Server without changing their situations on Gmail Server. I want to receive them 3 unread and 4 read as in server.
What should I do for doing that?
My connection code sample is:
public Message[] ConnectionToServer(String email, String password)
throws Exception
{
Properties props = System.getProperties();
props.setProperty("mail.imaps.partialfetch", "false");
URLName server = new URLName("imaps://" + email + ":" + password + "#imap.gmail.com/INBOX");
Session session = Session.getDefaultInstance(props, null);
folder = session.getFolder(server);
if (folder == null)
{
System.exit(0);
}
folder.open(Folder.READ_WRITE);
messages = folder.getMessages();
for (int i = messages.length - 1; i >= 23; i--)
{
Part p = messages[i];
subject = messages[i].getSubject();
if (messages[i].isSet(Flags.Flag.RECENT)) {
isSet = true;
System.out.println("Recent");
isSetlist.add(String.valueOf(isSet));
}
if (messages[i].isSet(Flags.Flag.SEEN))
{
isSet = false;
System.out.println("Read");
isSetlist.add(String.valueOf(isSet));
}
else
{
isSet = true;
System.out.println("Recent");
isSetlist.add(String.valueOf(isSet));
}
body = getText(p);
list.add(body);
}
return (Message[]) messages;
}
I am using getContent in getText() method
public String getText(Part p) throws MessagingException, IOException {
if (p.isMimeType("text/*")) {
boolean textIsHtml = false;
String s = (String) p.getContent();
textIsHtml = p.isMimeType("text/html");
return String.valueOf(s);
}
if (p.isMimeType("multipart/alternative")) {
// prefer html text over plain text
Multipart mp = (Multipart) p.getContent();

Access the message flags (to determine if the message is SEEN or not) before you access the content. Accessing the content normally sets the SEEN flag.
Try opening the folder in READONLY mode if you don't need to do any modifications - alternately, try preserving the Message flags across getContent calls.
