I AM USING THIS CLASS LIKE BELOW.THERE IS BUTTON AND WHENEVER I CLICK THE BUTTON IT SHOULD START FTP UPLOAD PROCESS IN BACKGROUND BUT I GET "PROGRAM HAS STOPPED UNFORTUNATELY" ERROR.
Assume that The ftp address and username password pathfile sections are true and I get the internet and network permissions already by the way ...
button1.setOnClickListener(new OnClickListener()
{
public void onClick(View arg0)
{
new Asenkron().execute("ftpaddress","username","pass","pathfileon telephone");
}
});
And here is the logcat for you to analyse the potential error and help me ...

By the way I changed the relevant code like that ;
instead of
catch (Exception e)
{
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
}
I replaced with this code
catch (Exception e)
{
HATA=e.toString();
}
And I added the code to button
textview1.setText(HATA);
So I can see the error on the textview and it is writing that
"Android java.net.UnknownHostException: Host is unresolved"
But i know that the ftp server is correct and I check the ftp server from the AndFTP application.
With the same address login and pass information ftp server is working.So the problem is in my code I think.Any help will be too much appreciated.Anyone who can help me I can give teamviewer to analyse what is the problem ...
