Operating Systems of Mobile Devices (OSMZ)
Instructor : Michal Krumnikl
Writing applications in Java or C# is relatively easy, but there are special cases, where the generated code is not very efficient. The examples of most demanding applications are computationally intensive algorithms or peripheral and network communications. In order to achieve better results, we have to use C/C++ with the possibility to directly access the OS resources. We will introduce the development of applications running directly on operating system and not using any extensions of CLR or Java environments. Students will learn how to use Android native development platform, Linux API. Implementations will be done in C/C++ and Java.
