Hi, folks
I'm now using Ftp Server v1.0.4 in my Android app, generally speaking, it's
working fine on Android 2.1 but I've found that some of my users may face a
configuration related error, here's the stack trace:
Uncaught handler: thread main exiting due to uncaught exception
java.lang.RuntimeException: Unable to start service

Seems it's a binding error, but I don't know where I am wrong, below is
code fragment I used in my app to configure the ftp server:
String user = settings.getFtpUserName();
String pass = settings.getFtpPassword();
SimpleAuth myAuth = new SimpleAuth();
List<Authority> auth_list = new ArrayList<Authority>();
auth_list.add(myAuth);
super.onStart(intent, startId);
// Create User
userFactory.setName(user);
userFactory.setPassword(pass);
userFactory.setHomeDirectory(root);
userFactory.setEnabled(true);
userFactory.setAuthorities(auth_list);
// Setup the User Mgr
userMgrFactory.setAdminName(user);
serverFactory.setUserManager(userMgrFactory.createUserManager());
// Get User Mgr
UserManager userMgr = serverFactory.getUserManager();
try {
userMgr.save(userFactory.createUser());
} catch (FtpException e) {
Log.v("FE", "Can not create user: " + e.toString());
this.stopSelf();
}
// Set Port
factory.setPort(settings.getFtpPort());
// Set Passive Ports
dataConnFactory.setPassivePorts("4000-4199");
factory.setDataConnectionConfiguration(dataConnFactory.createDataConnectionConfiguration());
// Replace with default listener
serverFactory.addListener("default", factory.createListener());
// Create Server
ftpServer = serverFactory.createServer();
// Start Service
try {
ftpServer.start();
} catch (FtpException e) {
Log.v("FE", "Can not start ftp server: " + e.toString());
this.stopSelf();
}
Could someone please help me to see where I am wrong? Thank you!
Alex
