Installation

1. Add CN1FileChooser.cn1lib to your project's lib directory and refresh your cn1libs.
2. If deploying to iOS, you'll need to make sure that your App ID includes iCloud support. (Currently it should not be associated with any iCloud containers).

Code Sample:

if (FileChooser.isAvailable()) {
    FileChooser.showOpenDialog(".xls, .csv, text/plain", e2-> {
        String file = (String)e2.getSource();
        if (file == null) {
            hi.add("No file was selected");
            hi.revalidate();
        } else {
           String extension = null;
           if (file.lastIndexOf(".") > 0) {
               extension = file.substring(file.lastIndexOf(".")+1);
           }
           if ("txt".equals(extension)) {
               FileSystemStorage fs = FileSystemStorage.getInstance();
               try {
                   InputStream fis = fs.openInputStream(file);
                   hi.addComponent(new SpanLabel(Util.readToString(fis)));
               } catch (Exception ex) {
                   Log.e(ex);
               }
           } else {
               hi.add("Selected file "+file);
           }
        }
        hi.revalidate();
    });
}
