OK, here is what I propose doing now. I would just like to know if it is robust or advisable:
I have a string named "root" that is initialized by my main activity as: root=getFilesDir().getAbsolutePath(); And I have a string called "currentFolder" that holds the current directory. It is initially equal to root, but it can change if the user changes to a subdirectory. When I want to access a document file I use: File f = new File(currentFolder, simpleFileName); To change the current folder I use: currentFolder = dirFile.getParent(); //..to navigate up the folder tree, or currentFolder = dirFile.getPath(); //..to navigate down the folder tree. where dirFile is a file representing a directory. Now for the "risky" part: I propose to save "relativeCurrentFolder" defined as: relativeCurrentFolder = currentFolder.substring(root.length()); This works based on the assumption that root should always be a prefix of currentFolder. Then when the app initializes, I can reconstruct currentFolder as: currentFolder = root + relativeCurrentFolder; That way, if the platform does change in a way that changes root, then currentFolder will always be properly reconstituted when the app starts up again. Does this seem risky or robust? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
