How about reusing someone else's class so you write less code?

Third party developers can use OI File Manager through simple intents to present an "Open file", "Save file", or "Select folder" activity.

The file manager features PICK_FILE and PICK_DIRECTORY intents:

Intent intent = new Intent("org.openintents.action.PICK_FILE"); startActivityForResult(intent, 1);

You can provide a pre-selected file or folder by setting data through setData() to a file URI, like "file:///sdcard/notepad.csv". The picked file URI can be obtained in onActivityResult() through getData().
