Conclusion
Quiz Maker is an easy to use Android application for making creative trivia games with textual, image and audio content. Users are enabled to create multiple quiz categories that can be password protected or not and set with options such as shuffle questions and answers. Data is available for transporting between Android devices in various file formats but this application needs a unique file format in order to make data much more transportable. It can be realized with Java serialization and that has yet to be researched and designed. Printable quiz like TXT and PDF document format content might be applied for school tests and that content can be used for a more interactive education. Students can be additionally prepared for exams and achieve increased knowledge.
