When building an Android application, it is easy to think of the platform as a collection of APIs: Activity, ViewModel, CameraManager, LocationManager, and so on.
But behind every API call is a layered system that manages application execution, memory, security, processes, and hardware communication.
Understanding these layers helps Android developers make better decisions about performance, debugging, permissions, and device compatibility.
You call
startActivity(). You never think about what happens underneath. That's the point of Android's architecture, but understanding the layers below your code is what separates developers who can only write features from developers who can debug ANRs, optimize cold starts, and reason about why a camera API behaves differently on a Pixel versus a Samsung device.
