Why AOSP builds take forever (and what actually helps reduce the wait time)

I’ve spent a lot of time working with large AOSP trees (automotive + embedded), and one thing that keeps coming up is how much build time teams quietly accept as “normal.”

What surprised me most over time wasn’t just how long builds take but *why* they take that long.

In practice, it’s usually not the size of AOSP alone. A big chunk of the pain comes from:

* Rebuilding the same framework and native components again and again across branches and CI
* Dependency bottlenecks high in the tree that leave cores idle
* Optimizing local machines while ignoring redundancy across the team

I wrote a longer breakdown of where AOSP build time actually goes, what helps (and what doesn’t), and the trade-offs teams run into when they try to speed things up.

If you’re dealing with long AOSP or embedded Android builds, I’m genuinely curious:
**what’s been the biggest issue for you?**

Do you still own a physical scanner, or is your Android phone enough now?

I realised recently I haven’t touched a physical scanner in years - all my adult paperwork (contracts, receipts, uni/HR forms) goes through my phone now. On Android I’m using a small app called Scanium as my default: open it, scan the page on the desk, tweak the borders if needed and save a PDF I can email or drop into Drive. Curious how it looks for others: are you fully phone-only for scanning these days, and which Android scanner app ended up sticking for you long term? 🙃

Dev I built RendrFlow: A privacy first, 100% offline AI Upscaler that runs entirely on-device (No cloud uploads)

Hi r/Android,

I am the developer of RendrFlow.

I built this app because I was tired of "free" upscalers that force you to upload your personal photos to a cloud server or hit you with a paywall after 3 edits. I believed our modern smartphones (Snapdragon/Tensor/Exynos chips) were powerful enough to handle these tasks locally, so I created an app that does exactly that.

try it:

If you have old, low-resolution photos or blurry shots that you want to fix without sharing them with a third-party server, this app is for you.

working (The Tech):

RendrFlow utilizes TensorFlow Lite and Android NNAPI to run Super Resolution models directly on your device’s hardware.

\- 100% Offline: You can put your phone in Airplane mode and it works perfectly.

\- Privacy: No data mining, no accounts, and no uploads. Your photos stay yours.

\- Optimization: It utilizes TFLite delegates to accelerate processing on your GPU/CPU.

Main Features:

\- AI Super Resolution: Upscale up to 16x (Choice of "High" speed or "Ultra" detail).

\- Background Removal: Instantly create transparent PNGs.

\- Batch Tools: Queue multiple images to upscale or convert (JPEG/PNG/WEBP/PDF) while you do other things.

Device Support:

I’ve optimized it for modern Android devices. Since it relies on your hardware, results may be faster on flagship chips , but it is fully functional on mid-range devices too.

I’d love for you to give it a spin and let me know how the inference speed feels on your specific device model!

What app do you use daily?

What are some small apps or tools you genuinely use every day?

Not big social media apps like Instagram or TikTok — I’m more curious about simple utilities or tools that quietly stay on your phone and actually get used daily.
