Android Question write a text file on server

It the server is running a http server then you can upload the image to the http-server which saves it on disc. HTTP Server with php-capabilities for example.
Or a Servier running a FTP. Upload it with ftp .

You are not providing enough informations. It fully depends on the server implementation.

sorry, you are right
It's my server .. I can do what I need ..
something like samba or nfs, so that it is seen as a cell phone memory does not exist?

There is a SMB library but it does not work with the newest SMB Protocol.

There is no Network-attached-storage in Android.

Best is to use FTP or such....
