I am using Facebook’s API to create a new album with a picture from my android app but I keep on getting these annoying errors that make no sense. I have done some research but have come up with nothing. Please help!

android bytearray byte arrayindexoutofbounds
I am receiving a ByteArray in Android through LocalBroadcastManager. It works fine, however I send it in chunks.When I want to merge back the chunks, I get an error.Here is the code:else if (message.equals(BtConstants.BtStateUpdates.BT_UPDATE_STATE_RXRAW_COMPLETE.getString())) {Log.i(TAG, “length [” + Integer.toString(picRaw.length()) + “] / capacity [” + Integer.toString(picRaw.capacity()) + “]”);Log.i(TAG,”append” + Integer.toString(intent.getExtras().getByteArray(BtConstants.btBytePayload).le

string gwt bytearray
The String(byte[] bytes) constructor and String.getBytes() method are not implemented by GWT JRE emulation String class. Does anybody know of an implementation? I do not want to use char[], But it seems like there is no other solution.

flex image air bytearray
I have recently figured out how to use an SQLite db with Flex. Now I’m having trouble displaying the data properly. I’ve tried several binding strategies and I’ve largely come up short. I had undefined property errors, unusable errors, and finally! Code without errors! Also, code without a displayed image. Any help is appreciated as always. Here’s my code so far; trying to keep it tidy, Async, and I’ve left an unused variable or two from my messing around with it. Thanks for any insight.<?xm

c# string bytearray bitarray huffman-encoding
Possible Duplicate Converting byte array to string and back again in C#I am using Huffman Coding for compression and decompression of some text from hereThe code in there builds a huffman tree to use it for encoding and decoding. Everything works fine when I use the code directly.For my situation, i need to get the compressed content, store it and decompress it when ever need.The output from the encoder and the input to the decoder are BitArray.When I tried convert this BitArray to String and ba

perl loops bytearray
Thanks to everyone in advance.I’d like to access the nth byte of a binary scalar. For example you could get all the file data in one scalar variable…Imagine that the binary data is collected into scalar… open(SOURCE, “<“, “wl.jpg”); my $thisByteData = undef; while(<SOURCE>){$thisByteData .= $_;} close SOURCE; $thisByteData is raw binary data. When I use length($thisByteData) I get the byte count back, so Perl does know how big it is. My question is how can I access the Nth byte?S

c# .net networking .net-3.5 bytearray
I have a byte array that represents a complete TCP/IP packet. For clarification, the byte array is ordered like this:(IP Header – 20 bytes)(TCP Header – 20 bytes)(Payload – X bytes)I have a Parse function that accepts a byte array and returns a TCPHeader object. It looks like this:TCPHeader Parse( byte[] buffer );Given the original byte array, here is the way I’m calling this function right now.byte[] tcpbuffer = new byte[ 20 ]; System.Buffer.BlockCopy( packet, 20, tcpbuffer, 0, 20 ); TCPHeade

I am coding a class that compares the files of two directories via comparing the Byte arrays of each file. I am however not getting the expected results; identical files are not being resolved as identical files.First problem:Matching the files Byte[] with equals() resolves to false with matching files (Checked with only one file as to circumvent the possible index misalignment issue; the check still resolves to false.).Second problem:When using Vector’s containsAll() for checking that both Vect

java encryption for-loop error-handling bytearray
Working on a bit of encryption using des in java. I have a bunch of methods as well as some junit test cases. The method im having trouble with receives a byte array and an int and at that position (int) it flips the bit. so like using an 8 byte byte Array with 64 bits in total it receives the hex byte array [ ad 12 45 67 c3 65 3a 66 ] transforms it into a 64 bit long binary string and flips whatever position. This method passes the test cases in junit (which were given to me) but now im trying

I would like to be able to move images into and out of Flex by converting back and forth between ByteArrays. I’ve been having some trouble with this, so I designed a simple test program, and even that I can’t get to work. Here’s the code I’m trying right now:protected function button3_clickHandler(event:MouseEvent):void { var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderCompleteHandler2); loader.load(new URLRequest(“file:///c:/win.jpg”)); }private

I’m converting a 2.6.5 application to python 3.1. I’m trying to convert a byte order received through socket.recv() into a string, by doing the following:str(temp, ‘UTF-8’, ‘ignore’)The problem is unknown characters are removed (“ignored”), such as \x00 and \xff (WebSockets characters), I do want to convert the byte order to a string before removing \x00 and \xff. I’ve checked the documentation and there is no correct error handling option (like a ‘leave’, f.e.) – is there some other way to acco

java android sockets bytearray outputstream
I have a “server” running in java and I am sending files via byte array to a “client” (android system). The functionality works fine, but I’ve noticed when I try to send larger files (1MB+), it doesnt successfully write all the bytes before closing (Ex: tried sending 5mb, and it only sent 902 bytes). Is there a way to have the code wait for the stream to finish writing before closing the stream? Below is the code and the stack trace. Essentially the send message method is called when a file is a

We are running a file sending app on a client server. The app convert files to ByteArray and send it to a web service.At the beginning, we don’t have the right to change C:/ Drive. The app comes an error message: “Could not find a part of the path C:/temp/[hash code name].tmp”Then we asked the administrator to give us a full control of it, and I manually created the temp folder, then it works.The next day, when we restart the app, it no long sends file, instead it gives us this message. “Could n

I was unable to find something similar to my application so I thought I would ask a new question. I am new to developing android (and java in general) but have some prior programming experience in C and Visual Basic. I am using a JPEG TTL Camera (Link Sprite LS Y201) and taking a picture to send from a TCP server to an android client device. On the client side, I am using an Async task to continuously get the data from the socket. So far, I have been able to get some bytes and store them in an
