I'm writing a simple app to copy a file to a share on my local Windows network, but am getting the errors below when executing the code. I'm using the JCIFS libraries, and SmbFileOutputStream.
java.lang.RuntimeException: An error occured while executing doInBackground()

The target share and folder have full control permissions set for Everyone (it's on a Windows 2008 server). I have also tried a shared folder on a Windows 7 workstation but got the same error. The code, and permissions in my Android manifest, is below. I have enabled these permissions for the app: ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE, INTERNET
class CopySMBFile extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected String doInBackground(String... f_url) {
try {
String fileContent = "This is a test file";
try{
String user = "myusername:mypassword";
System.out.println("User: " + user);
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(user);
String path = "smb://192.168.1.4/k/temp/fileName.txt";
System.out.println("Path: " +path);
SmbFile sFile = new SmbFile(path, auth);
SmbFileOutputStream sfos = new SmbFileOutputStream(sFile);
sfos.write(fileContent.getBytes());
System.out.println("Finished attempt to write file");
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
Log.e("Connected", e.getMessage());

return null;

Any ideas for how to fix (or further diagnose) this?
Move your <uses-permission> elements to be peers of <application>, not children of <application>.
