+# Android WalletKit Demo
+
+Demo app for TON WalletKit SDK.
+
+## Setup
+
+Build SDK first:
+
+```bash
+cd ../TONWalletKit-Android
+./gradlew buildAndCopyWebviewToDemo
+```
+
+Then open this project in Android Studio and run.
+
+## Features
+
+- Wallet creation and import
+- TON Connect integration
+- Transaction signing
+- Balance display and auto-refresh
+
+## Engine Selection
+
+Edit `WalletKitDemoApp.kt`:
+
+```kotlin
+val defaultEngineKind = WalletKitEngineKind.WEBVIEW // Recommended
+```
+
+For QuickJS: use full variant and uncomment OkHttp in `app/build.gradle.kts`.
+
+## Structure
+
+- `ui/` - Compose screens
+- `viewmodel/` - State management
+- `storage/` - Secure wallet storage
+- `libs/bridge-release.aar` - SDK (copied by build task)

+# Android WalletKit
+
+TON blockchain wallet SDK for Android.
+
+## Structure
+
+- `TONWalletKit-Android/` - SDK library
+- `AndroidDemo/` - Demo app
+- `js/` - TypeScript source for bridge
+
+## Quick Start
+
+```bash
+# 1. Build JavaScript bundles
+pnpm install
+pnpm run build:all
+
+# 2. Build SDK and copy to demo
+cd TONWalletKit-Android
+./gradlew buildAndCopyWebviewToDemo
+
+# 3. Run demo
+cd ../AndroidDemo
+./gradlew installDebug
+```
+
+## Build Variants
+
+- **webview** (1.2MB): WebView only, no native libs
+- **full** (4.3MB): WebView + QuickJS with native libs
+
+Use webview for production.
+
+## Development
+
+Use Android Studio run configurations:
+- "Build WebView & Copy to Demo" - default workflow
+- "Build Full & Copy to Demo" - test QuickJS variant

+# TON WalletKit Android SDK
+
+Android library for TON blockchain wallet integration.
+
+## Variants
+
+- **webview**: 1.2MB, WebView only (recommended)
+- **full**: 4.3MB, WebView + QuickJS (deprecated, 2x slower)
+
+## QuickJS Source (Reference Only)
+
+QuickJS source removed from repo. If needed locally:
+```bash
+cd bridge/src/main/cpp/third_party/
+git clone https://github.com/bellard/quickjs-ng.git
+```
+
+## Building
+
+```bash
+./gradlew assembleWebviewRelease
+./gradlew assembleFullRelease
+
+# Build and copy to demo app
+./gradlew buildAndCopyWebviewToDemo
+```
+
+## Integration
+
+Copy AAR to your `app/libs/` and add:
+
+```kotlin
+dependencies {
+ implementation(files("libs/bridge-release.aar"))
+ implementation("androidx.webkit:webkit:1.12.1")
+ implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.6.3")
+ // For full variant only:
+ // implementation("com.squareup.okhttp3:okhttp:4.12.0")
+}
+```
+
+## Usage
+
+```kotlin
+val walletKit = WalletKitEngineFactory.create(
+ context = applicationContext,
+ kind = WalletKitEngineKind.WEBVIEW
+)
+```
+
+## Structure
+
+- `src/main/` - Common code, WebView engine
+- `src/full/` - QuickJS-specific code
+- `src/main/cpp/` - Native libraries
