Hi,

I just used your tutorial and it perfectly works but I have a question:

is it possible to resize the list or lunch it in a little Layout because I would add some buttons...

Its maybe simple but its my first application.

Thanks

A little Up ^^

Do you miss .this.deleteFile(String) is an abstract method. I used but android state error. I'm going to 'raise level' your version. I want to make it(Browser of you) be able to copy,paste,move,delete...I think this is rather "difficult" because class File don't support much, but I 'll try. Thanks for tutorial, you're great . If you know much about File class in android. Please reply me fast :wink:

I m also working on this actually. And i am very new in this field. Can u help to find out how to make my browser able to cut, copy,paste,show file or folder details and create new folders ? If u provide any tutorial on any site plz also help me by providing that. I have an university project on this. So this is very urgent to me. Thanks in advance. My yahoo mail id: rasam_hossain@yahoo.com

can any one help as android development is new for me..??
thank u..

Hi great tutorials! Is there a way to lock the user to a home directory? I created a directory called My Webs and I got the liat to load the files and subdirectories in My Webs, but using the upOneLevel button the user can navigate to the filesystem root. This is what I've tried.

Code: Select all


private String rootdir = Environment.getExternalStorageDirectory() + "/My Webs";
protected void onListItemClick(ListView l, View v, int position, long id) {
                ...
                if (selectedFileString.equals(getString(R.string.up_one_level)) && currentDirectory.getAbsoluteFile().toString()!=rootdir) {
                        this.upOneLevel();
                }
}
