The AOSP build process is fairly well understood by now: sync the source code, add device-specific drivers and kernel, and build the target image. I had built AOSP before to debug certain issues, but official support for Pixel 3 XL only goes up to Android 12. Recently, while working on Chromium development, I needed to test WebView on a newer platform, so I used LineageOS 21 for the build instead. ...
In Android dependency management, it’s common to configure multiple remote repositories like jcenter, jitpack, google(), and more. Some large projects, such as “Zuiyou”, depend on over 10 repositories. This becomes a significant problem during initial project setup, dependency changes, or network issues — troubleshooting builds becomes a nightmare. I had noticed this issue long ago but kept putting off addressing it. This post documents the Nexus setup process. Installing and Configuring Nexus Prerequisite: JDK 8+. ...

While building a project, I discovered the shrinkResources attribute, which removes unused resources from the APK. Here is how to configure it and what to watch out for. ...
I had long wanted to write a tree view demo. Previously, I used TreeViewList (a ListView wrapper) or ExpandableListView for multi-level menus. Eventually I realized there is no need for custom views – just use RecyclerView and manage the data flattening yourself. The core idea: recursively flatten a nested data structure into a linear list, then use notifyItemRangeInserted / notifyItemRangeRemoved to handle expand and collapse. ...
