AppMint integration guide

Everything a page inside a generated app can do - purchases, ads, push, sign-in, databases, the phone's own hardware - written as 358 numbered steps across 47 chapters. This is the same guide that ships inside the AppMint app, published here so you can read it on a laptop, link to a single step, and hand it to whatever you use to write code.

Start here

What the builders are, what an app costs to make, and how to give them something to build.

Free AI App Builder

Describe an app in plain words and get a real APK, with no key and no account.

AppMint AI (How Credits Work)

What one Mint buys, what a typical app costs to generate, and why editing is cheaper than creating.

AI App Studio (Bring Your Own Key)

Run the AI pipeline on your own OpenAI, Anthropic or OpenRouter key instead of Mints.

Writing HTML for your app

How a page inside the app differs from a page in a browser tab, and the rules that keep it working.

React & Framework Apps

Build settings, routing and asset paths for framework projects that have to run from a file:// origin.

App Icon & Splash Screen

Adaptive icons, the splash screen, and the sizes Android actually uses.

ZIP to APK

Upload a React, Vue or plain HTML project and have it bundled into an APK unchanged.

HTML to APK

Paste one self-contained HTML page, or upload the .html file, and get a signed APK - no AI round, no Mints.

JSX / React Runtime

Run raw JSX with no build step by loading React and Babel at runtime.

Making money

In-app purchases, subscriptions, ads and card payments inside a generated app.

Stripe Payments

Take card payments for physical goods and services, where Play billing is not required.

Banner, interstitial and rewarded ads, the consent rules, and the mistakes that stop ads serving.

Sell one-time unlocks and subscriptions from your own page, with live Play prices and offline entitlement checks.

Prebuilt wiring for payment gateways, WhatsApp, Maps and other third-party services.

Backend and accounts

Databases, sign-in and live chat, wired without running a server.

Supabase Backend (Connect It Once)

Connect a Postgres database, auth and storage once, and let the AI write against it.

Firebase Backend (Database + Accounts)

A hosted database and user accounts for an app with no server of its own.

Google Sign-In (Continue with Google)

A real "Continue with Google" button inside a generated app, and the SHA-1 that makes it work.

Tawk.to Live Chat

Put a staffed live-chat widget in the app without touching your website.

Notifications

Push from a server, and reminders scheduled on the device itself.

Local Notifications & Reminders

Schedule reminders on the device - no server, no internet, exact alarms included.

AppMint Push - Notify Your Users

Send a notification to every installed copy of your AppMint app from a web dashboard.

OneSignal Integration

Use OneSignal instead, for segments, scheduling and delivery reporting.

Device features

The JavaScript bridge: sensors, files, media, camera, biometrics and the rest of the phone.

JavaScript bridge API

Every native method a page can call inside a generated app - 152 of them, extracted from the runtime.

Lock the app to one screen for a shop counter, a museum or a demo unit.

Picture-in-Picture (PiP)

Float the video in a corner while the user does something else.

Sensors, Files & Background Jobs

Accelerometer, Bluetooth sensors, file access and work that keeps running when the app is closed.

Native Fullscreen Video

Media Notification Bridge

Lock-screen controls, artwork and the seek bar for audio your page is playing.

/llms.txt

The index: what this site is, and every documentation page with a one-line summary.

/docs/llms-full.txt

The entire guide - every chapter, every step - in one file.
