bytearray

问题 I'm trying to prepend the byte array of a sound object to a captured microphone sound byte array. It works, but the extracted sound object get pichted down and doubled in length. I guess this is because the byte array of the sound object is in stereo, while the mic byte array is in mono. I have this: sound.extract(myByteArray, extract); myByteArray now contains the stereo data. How can I turn this to mono (I'm new to ByteArrays). UPDATE: Here's a working solution: existingByte.position = 0;

问题 I'm passing a drawable to bitmap which then gets turned into a bytearray and back again. This however causes an error with onReceive.

问题 i need to write a php web service to output file to a Windows client application. I have two choice Byte Array and Streaming. Which one is better and easy to implement in PHP? Thanks for your assistance. 回答1: How about just.... $file = 'some_file.exe'; $_size = filesize($_file); header('Content-Type: binary/octet-stream'); header('Content-Length: '.$_size); header('Content-Disposition: attachment; filename="' . basename($file) .

问题 I was writing a program to convert a String fed IP-Address to IP-Address by utilising the method InetAddress.getByAddress(byte[] addr) . So, what I did was input IP-from the user in the form of String. Parsed it and splitted the IP on . using String.split("\\.") . Then, I started converting that String array into byte array where I am right now stuck on. Please help me to get rid of this situation. Any workaround OR alternate way of accessing this will be heartly appreciated... The code goes

问题 Our web application has a feature which uses Flash (AS3) to take photos using the user's web cam, then passes the resulting byte array to PHP where it is reconstructed and saved on the server. However, we need to be able to take this web application offline, and we have chosen Gears to do so. The user takes the app offline, performs his tasks, then when he's reconnected to the server, we "sync" the data back with our central database. We don't have PHP to interact with Flash anymore, but we

问题 I have captured video and I get a URI of that video. How to load the content pointed to by that URI into byte[] structure? 回答1: Have a look at ByteArrayOutputStream, FileInputStream, and File(URI uri). Code example: ByteArrayOutputStream baos = new ByteArrayOutputStream(); FileInputStream fis = new FileInputStream(new File(yourUri)); byte[] buf = new byte[1024]; int n; while (-1 != (n = fis.read(buf))) baos.write(buf, 0, n); byte[] videoBytes = baos.toByteArray(); 回答2: I realize this question
