Runs in its own process and with its own instance of the Android Runtime System loads the library module for that hardware component.įor devices running Android version 5.0 (API level 21) or higher, each app When a framework API makes a call to access device hardware, the Android Modules, each of which implements an interface for a specific type of hardwareĬomponent, such as the camera or Bluetooth module. Hardware abstraction layer (HAL) provides standard interfaces that exposeĭevice hardware capabilities to the higher-level Java API framework. Security features and lets device manufacturers develop hardware Using a Linux kernel lets Android take advantage of key Underlying functionalities such as threading and low-level memory management. The Android Runtime (ART) relies on the Linux kernel for The foundation of the Android platform is the Linux kernel. So i’m excited to see if I can put C4 to use as I have those levels thought out in my head but on top of that, I just want a clean and well usable app that shows all these diagrams and levels in an understandable way.Android is an open source, Linux-based software stack created for a wideĪrray of devices and form factors. Those 3 first ones would give a lot of info to anybody unfamiliar with our software landscape or tech stack.īut it would be super easy and intuitive to use if you could easily zoom in and out of the parts of the whole system and you’d have a lot of additional related links and info also available. And then in the third level you’d see what components do for example the BE app consist of, possibly listing its ip and server locations etc as well.Īnd i guess the fourth level would be code level components but at this moment, this would not give the most benefits even so i’m not yet concerned about that. I’m a rather new architect as well and haven’t yet tried to put C4 to practice, but i have been thinking that we need different levels of system diagrams where on the first/highest level you can see all systems and lines between them representing data movement (integrations) between them.Īnd then i’d want to click on a specific system/app box and i zoom in into that app’s overview diagram (be/fe/db etc containers) and either at this stage or in the next detailed view i want to also show additional information in tech stack description, links to our gitlab repo and confluence page etc. otherwise you're going to end up in the same situation in the future again. If you do gown that route, my recommendation would be to define the abstractions that you want to use and have these agreed with your team. LikeC4, Ilograph, etc) sounds appealing, but in many cases it's just papering over the cracks, and not solving the root problems of teams not being precise about how they think about, describe, and talk about their codebases. Having an arbitrary number of levels of abstraction (e.g. These discussions push teams to be more precise with their language, which is ultimately what we need to do as an industry if we're ever going to move towards something more akin to an engineering-based discipline. One of the big themes from the talk is this: the value of the C4 model isn't the fancy hierarchical diagrams, it's the limited set of abstractions that force teams to have discussions such as, "is X a container or a component?".
