Agents will allow human programmers to get what they've been begging for decades now: proper requirements and flexible, logical, tooling.

this has been my sort of big tent alignment with AI people. If I'm getting good CLI tooling that _actually works_ (or fixes to existing ones that have been busted forever) then I'm pretty happy.

Things that make systems more understandable to the LLMs ... usually make things more understandable for humans as well. Usually.

The biggest issue I've found is that vibed up tooling tends to be pretty bad at having the right kind of "sense" for what makes good CLI UX. So you still have awkward argument structures or naming. Better than nothing though

Any textbooks or resources on getting better at naming things?

The Programmers Brain book was my go to

I've been thinking the same thing lately. It's sorta frustrating that it required bots to force tech companies to make clean simple cli driven development workflows.
qingcharles [3 hidden]5 mins ago
It's wild that it took AI to get half the companies on the planet to actually add reasonably priced APIs to their products so I don't have to puppeteer every damn thing with a flakey harness.

...and once this goal is finally reached the programmer will breathe a sigh of relief and then promptly be fired since now the machine can do the job as well as they could.

The tooling in 2026 is so easy you can do almost anything without AI very very quickly.

The install command shown for Windows is 404.

`curl -fsSL https://dl.google.com/android/cli/latest/windows_x86_64/inst... | bash`

The URL shown for individual OSs work, but the script errors for me.

`curl.exe -fsSL https://dl.google.com/android/cli/latest/windows_x86_64/inst... -o "%TEMP%\i.cmd" && "%TEMP%\i.cmd"`

I manually downloaded the exe, but it say socket error. vibe coding is going strong!

Wow. Thanks for this update. It streamlined a lot of tasks.

Apart from this, next step will be to add suport for building android apps on the android phones itself. No desktop needed.Building on the laptop with agents and installing the build in the phone and testing doea not seem AI native. If everything can run on my android phone, development cycle will speed up.

you already could! just install Termux, npm install your favourite agent harness (pi for one has explicit Termux support, but its AGENTS.md works just fine with Claude Code for example - https://github.com/badlogic/pi-mono/blob/main/packages/codin...), and say you want an android app. It problem solves for a bit, then spits out an apk out to your Downloads folder.
smalltorch [3 hidden]5 mins ago
You actually can right now on termux.
rvillberg [3 hidden]5 mins ago
This is a good step forward, but keep in mind the claimed gains are about "project and environment setup", not the tasks you deal with on a daily basis in an existing project.
anabis [3 hidden]5 mins ago
Taking screenshots, optionally with component borders highlighted, and operating the UI with element names like "button1" instead of tap 200,30 looks useful. If I could get it to work.
whstl [3 hidden]5 mins ago
I wish the same thing existed for Apple.

Everything I do for macOS/iOS is already without Xcode but it's a pain in the ass to keep up with changes, and there are things I haven't figured out yet (like AUv3).

>Google collects usage data for the Android CLI, such as commands, sub-commands, and flags used. This data does not include custom parameters or identifiable information. This information helps improve the tool and is collected in accordance with Google's Privacy Policy.

No thanks, is there no env variable for this? Doesn't Google have enough data already?

gowld [3 hidden]5 mins ago
Android CLI can write a tool that wraps android-cli and automatically passes the flag based on an env variable.

How would Google have enough data about a brand new product without collecting that data?

panzi [3 hidden]5 mins ago
`alias android-cli='android-cli --no-metrics'`
SJMG [3 hidden]5 mins ago
Uh do aliases load in non-interactive shells?
tredre3 [3 hidden]5 mins ago
> How would Google have enough data about a brand new product without collecting that data?

They wouldn't. But on the other hand, they probably have a large amount of in-house Android app developers on whom they can conduct such metrics collection. I wouldn't expect outsiders to have vastly different workflows, because when you get out of the happy path with Android all you get is pain.

jadar [3 hidden]5 mins ago
This is great. We also need a tool to expose source jars to agents so they don’t need to compress. There’s a lot of Compose overloads that Claude just guesses at. I built something internally but it needs polish and Claude really struggled with the deep Gradle integration.
antirez [3 hidden]5 mins ago
Let's see if even mid/big companies with tons of resources, with AI and the right tooling will continue to write webview-apps or, even worse, use some kind of multi target wrapper.
mridulmalpani [3 hidden]5 mins ago
How can I use this official android skill with Claude code?

Is there any step by step process or guidance on it?

cbhl [3 hidden]5 mins ago
Looks like the docs start here: https://developer.android.com/tools/agents/android-skills#us...

There's a link to a repo or you can use the CLI tool to init the skills

> Your agents perform best when they have a lightweight, programmatic interface to interact with the Android SDK and development environment.

F you google. Me too. Why didn't we get a sane way to build android apps before you had to please chatbots?

bitpush [3 hidden]5 mins ago
Damned if you do. Damned if you dont.
stavros [3 hidden]5 mins ago
Damned if you don't, damned if you do fifteen years later for an entirely different reason.

Catching up to Flutter.
firemelt [3 hidden]5 mins ago
flutter have this already?
diego_sandoval [3 hidden]5 mins ago
AFAIK, Flutter has had a good, capable CLI since the beggining. You've never needed to install Android Studio to use Flutter.
winrid [3 hidden]5 mins ago
I meant in terms of development speed with agents.
OutOfHere [3 hidden]5 mins ago
But can I publish an app without having to share my ID? I want an ecosystem that doesn't require it.
binkHN [3 hidden]5 mins ago
It's not just your ID; it's your address, phone number, and the list goes on.
Flavius [3 hidden]5 mins ago
Absolutely not. That would be crazy.
nout [3 hidden]5 mins ago
Zapstore or Obtanium...
Evidlo [3 hidden]5 mins ago
Now please let us install the apps just as easily
stronglikedan [3 hidden]5 mins ago
downloading an APK and opening it is already about as easy as it gets. the only thing easier would be for someone else to do it for you
throwaway81523 [3 hidden]5 mins ago
You're forgetting the installation ("sideloading", what everyone else calls installation) restrictions they are about to deploy. It will be a significant hassle to install anything without Google's approval. Many F-droid apps are showing warning notices about this upcoming change.
stavros [3 hidden]5 mins ago
"This APK cannot be scanned and its safety cannot be verified. Learn more/go back" and "learn more" has a link that looks like nothing but is actually a button to actually install the app.

I can think of some easier things, for example popping up a dialog, pressing "install" and having my all actually be installed after that.

What does this have to do with the Android CLI?

AnimalMuppet [3 hidden]5 mins ago
Since rafram is not the only one confused, yes, you really do.
rvz [3 hidden]5 mins ago
It isn't that hard to understand:

> Just wait until there are entire classes of vulnerabilities related to LLM usage

This is a valid concern.

There are going to be a new class of vulnerabilities which an LLM is involved which are going to be discovered and it will make it possible to cause catastrophic damage to a company; very easily.

This won't be surprising since we have companies building casual remote code execution tools for "agents" waiting to be hijacked.

AnimalMuppet [3 hidden]5 mins ago
I understand that. What about that relates specifically to the Android CLI? That was rafram's question, and mine, and as far as I can tell still hasn't been answered.

I mean, I guess if you're going to say "don't use LLMs", then you also don't want to let agents use the Android CLI, but it seems like raising an awfully general concern in a discussion about a very specific article.

vlapec [3 hidden]5 mins ago
That probably depends on how good 2026-era LLMs already are. But I hope you’re right, and that pre-AI devs will still make a real difference.
agentifysh [3 hidden]5 mins ago
Flutter CLI is what we really need but this is a welcome addition.
bartekpacia [3 hidden]5 mins ago
It exists already. Wdym?
