Walkthrough

We will define here all we need to know to deal with a multithreading environment like Android. It is crucial to understand what a thread is and what problems can occur while dealing with one. That is why we are focusing on the Java framework for a while, because every Android developer should know those notions, and then we will focus on how that platform is defined in Android and integrated with more objects. This provides multiple ways to separate execution at all levels, from the multithreading inside an application to the communication between different processes, defining a particular language to reach the target.
