/**

 * of a URI into NDEF.<p>
 * The uri parameter will be normalized with
 * {@link Uri#normalizeScheme} to set the scheme to lower case to
 * follow Android best practices for intent filtering.
 * However the unchecked exception
 * {@link IllegalArgumentException} may be thrown if the uri
 * parameter has serious problems, for example if it is empty, so always
