Presently, Network Browser should be able to connect to most Microsoft Windows or Linux and Mac OSX smb samba network shared folders. You need to know the IP address of the network server you are trying to connect to. You can connect as guest, or supply your username and password.
You can also open files that you find on your network. Tapping on a file will open it in the default editor on your Android system. Currently saving and uploading is not supported, but if there is interest in the project I can certainly work to add these features.
For some reason, there is an issue with the smb library that makes connection and loading times take forever if the username or password contains an @ symbol. I do not yet know how to fix this issue, but for the sake of usability, you will have like 500 times faster performance if you can make a username and password on your server that does not have an @ symbol.
Network Browser is for you guys, so if there is any interest in this project, I will add any features that you want or request. With time and effort this could be a fully functional network file manager and Windows Networking app, but if there is no interest in the project then I will not put the time into it. Just let me know!
