Using FilePicker to Import Files

FilePicker opens the native picker and returns the selected items as FilePicker.DFile. After the user selects a file, you can import it into a writable JAVARuntime.File.

Basic flow

1. Open the picker with FilePicker.open(...).
2. Read the selected DFile from the onSuccess callback.
3. Create a destination file using Directories.internal().
4. Import the file with DFile.importTo(destination) or FilePicker.importFile(...).

Example

FilePicker.open(new FilePicker.Listener() {
    public void onSuccess(List<FilePicker.DFile> files) {
        if (files == null || files.isEmpty()) {
            return;
        }

        FilePicker.DFile selected = files.get(0);
        File destination = new File(Directories.internal() + "/imports/" + selected.getName());

        selected.importTo(destination);
    }

    public void onCancel() {
        Terminal.log("Picker cancelled");
    }

    public void onError(String error) {
        Terminal.log(error);
    }
});

Notes

• Directories.internal() returns project/internal in the editor and the app data folder in the APK.
• Create the target folder first if needed.
• If you already have a DFile, you can call importTo(destination) directly.
