Trouble with the SelectFile library (Android mode)

When running the SelectFile library example I get a Fatal Exception error. Can someone explain me why? Thanks.

import select.files.*;

SelectLibrary files;

void setup() { size(320, 240);

files = new SelectLibrary(this);

files.selectInput("Select a file to process:", "fileSelected"); // files.selectFolder("Select a folder to process:", "fileSelected"); // files.selectOutput("Save the file please:", "fileSelected"); }

void fileSelected(File selection) { if (selection == null) { println("Nothing was selected."); } else { println("User selected " + selection.getAbsolutePath()); } }
