# Filechooser for [Codename One](https://www.codenameone.com)

Supported Platforms:

* Javascript

* iOS

* Android

* Simulator (JavaSE)

## Installation

For instructions on installing cn1libs, see https://www.codenameone.com/blog/automatically-install-update-distribute-cn1libs-extensions.html[this tutorial].

### Alternate Maven Installation

If your project uses Maven, the above installation instructions will still work, but you can alternately simply add the Maven dependency to your common/pom.xml file:

```xml

  com.codenameone

  filechooser-lib

  1.0

  pom

```

**IMPORTANT:** If deploying to iOS, you'll need to make sure that your App ID includes iCloud support, and you must associate with at least one iCloud container.  [See iOS setup instructions here](https://github.com/shannah/cn1-filechooser/wiki/iOS-Setup)

## 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();

    });

}
