     * Android L (lollipop, API 21) introduced a new problem when trying to invoke implicit intent,

     * "java.lang.IllegalArgumentException: Service Intent must be explicit"

     *

     * If you are using an implicit intent, and know only 1 target would answer this intent,

     * This method will help you turn the implicit intent into the explicit form.

     *

     * Inspired from SO answer: http://stackoverflow.com/a/26318757/1446466

     * @param context

     * @param implicitIntent - The original implicit intent

     * @return Explicit Intent created from the implicit original intent
