Is there any course about Android "administration"? I mean there are plenty of content on Linux/Windows administration (not programming): partitions, file systems, bootloaders, boot sequence, kernels, init(ialization), processes, shells, users, configuration, application installation and execution, logging, security, etc. How all of the components fit together, what interacts with what, and so on. When I first got my phone was looking for an Android course which would explain all the above concepts (and more, like what is launcher, how notifications work, what other APIs there are, location, camera, microphone, etc.). But didn't find anything, only found courses/books about application development in Java/Kotlin. I have no interest in Android programming, just want to know how it works.
