ioexception

I am trying to create a file on the filesystem, but I keep getting this exception: java.io.IOException: No such file or directory I have an existing directory, and I am trying to write a file to that directory. // I have also tried this below, but get same error // new File(System.getProperty("user.home") + "/.foo/bar/" + fileName); File f = new File(System.getProperty("user.home") + "/.foo/bar/", fileName); if (f.exists() && !f.canWrite()) throw new IOException("Kan ikke skrive til filsystemet " + f.getAbsolutePath()); if (!f.isFile()) { f.createNewFile(); // Exception here } else { f

I have the following example of reading from a buffered reader: while ((inputLine = input.readLine()) != null) { System.out.println("I got a message from a client: " + inputLine); } The code in the loop println will be executed whenever something appears in the buffered reader ( input in this case). In my case, if a client-application writes something to the socket, the code in the loop (in the server-application) will be executed. But I do not understand how it works. inputLine = input.readLine() waits until something appears in the buffered reader and when something appears there it returns

My app plays audio resource files from the internal directory designated for my app (/data/data/com...). It seems to download the files to that location okay, setDataSource(String path) doesn't throw any exceptions, but MediaPlayer.prepare() throws IOException.The same code works on the SD card. Why is this happening? EDIT: Let's assume this is the code; it's simpler than my code and it throws the same exception: package com.app.MediaPlayerTest; public class MediaTest extends Activity { MediaPlayer mp; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate

I'm running into a strange problem while reading from an InputStream on the Android platform. I'm not sure if this is an Android specific issue, or something I'm doing wrong in general. The only thing that is Android specific is this call: InputStream is = getResources().openRawResource(R.raw.myfile); This returns an InputStream for a file from the Android assets. Anyways, here's where I run into the issue: bytes[] buffer = new bytes[2]; is.read(buffer); When the read() executes it throws an IOException . The weird thing is that if I do two sequential single byte reads (or any number of single

I'm writing a simple program that reads and processes file content using a BufferedReader . BufferedReader br = new BufferedReader( new InputStreamReader(System.in) ); System.out.println("Enter the file name to read"); String fileName = br.readLine(); br.close(); // Process file contents br = new BufferedReader( new InputStreamReader(System.in) ); System.out.println("Enter another file name to read"); fileName = br.readLine(); br.close(); But when I call second br.readLine() to read another file name, I get the following exception: Exception in thread "main" java.io.IOException: Stream closed

I am pretty confused its an android problem or Java problem it self. When I was debugging an android application which works with Bluetooth, flow stopped on an catch block of IOException in which I later found out that exception e was null.... It was thrown when I was trying to read from an InputStream Yes it was not a NullPointerException but other kind of exception which is null- Better say thrown un-initialized. Is it possible? In which scenario such unitialized exceptions can be thrown?? Stephen C Is it possible? In which scenario such unitialized exceptions can be thrown?? This is not

I received a very weird IOException when writing to an XML file: System.IO.IOException: The requested operation cannot be performed on a file with a user-mapped section open. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at System.Xml.XmlTextWriter.
