Creation - geographical determination and sharing notes - data
This diploma thesis was developed within the framework of the Advanced Information Systems (MSc) Advanced Informatics Systems, specifically in the context of the software development course for mobile devices under the guidance of Professor Alepis. The dissertation was developed in Android Studio and has as its main theme the creation of notes, the geographic topology of the recording of each note geographically as well as the sharing of each note to an individual or several individuals. In closing, I want to thank Mr. Alepis for introducing and deepening the concepts and the Android software as well as those who helped me selflessly for the knowledge they have given me on this subject.
