The topic of this final paper is android applications development. Considering that android application development requires a sufficient level of knowledge of Java programming language, this final paper will cover its basis as well. Besides Java, XML programming language will also be used. Software used for development is Android Studio. Coverage of Java synthax, as well as functions and groups will be explained in the theoretical part of this final paper. After covering theoretical basis, there will be a set of educational and fully functional applications which will show how to apply theoretical knowledge. This final paper is meant to be used as a manual for developers while developing applications for Android platforms. To avoid any unnecessary confusion and eventual mistakes, most of the terms and functions will be written in its original english form, because coding synthax uses english as a base language for the programming languages. When a specific term is encountered for the first time, there will be an explanation of it.
