Having done the user interface part of the app, we will now turn to a native API and implement the sound recording and playback logic using the suitable Android Java classes, MediaRecorder and MediaPlayer.

Technically, both Python and Java are object-oriented, and it may even appear at first glance that these languages are rather similar. The utilization of OOP principles, however, differs radically. In comparison to Python, many Java APIs suffer from (or enjoy immensely, depending on who you ask) over-architecting and general overuse of the object-oriented paradigm.
