+The `Sources/SwiftAndroid/Documentation.docc` directory contains a DocC documentation catalog for Swift on Android. To build and preview it locally:
+
+```shell
+swift package generate-documentation --target SwiftAndroid --transform-for-static-hosting --output-path docs
+python3 -m http.server 8000 --directory docs
+```
+

+# Building for Android
+
+Cross-compile Swift code and package it into Android applications
+
+## Overview
+
+Swift on Android uses cross-compilation: you build on a macOS or Linux host, and the compiler produces native ARM or x86_64 binaries targeting Android.
+
+```shell
+$ swift build --swift-sdk aarch64-unknown-linux-android28
+```
+
+## Conditional compilation
+
+Use `#if os(Android)` to conditionalize code for Android:
+
+```swift
+#if os(Android)
+import Android
+#elseif canImport(Darwin)
+import Darwin
+#endif
+```
+
+## Foundation
+
+Foundation networking types require a separate import on non-Apple platforms:
+
+```swift
+import Foundation
+#if canImport(FoundationNetworking)
+import FoundationNetworking
+#endif
+```
+
+## JNI integration
+
+Export Swift functions for JNI using `@_cdecl`:
+
+```swift
+@_cdecl("Java_com_example_MyClass_hello")
+func hello(env: UnsafeMutablePointer<JNIEnv>, thisObj: jobject) -> jstring {
+    return env.pointee.pointee.NewStringUTF(env, "Hello from Swift")!
+}
+```

+# Getting Started
+
+Install the Swift toolchain, Android NDK, and Swift SDK for Android
+
+## Overview
+
+Development requires three components:
+
+1. **Swift Toolchain** -- install with [swiftly](https://github.com/swiftlang/swiftly): `swiftly install latest`
+2. **Android NDK** -- download from [developer.android.com](https://developer.android.com/ndk/downloads) (r27d+ recommended)
+3. **Swift SDK for Android** -- install with `swift sdk install` (see [swift.org](https://www.swift.org/documentation/articles/swift-sdk-for-android-getting-started.html))
+
+## Hello World
+
+```shell
+$ swift package init --type executable
+$ swift build --swift-sdk aarch64-unknown-linux-android28
+$ adb push .build/aarch64-unknown-linux-android28/debug/HelloWorld /data/local/tmp/
+$ adb shell /data/local/tmp/HelloWorld
+Hello, world!
+```
+
+## Target triples
+
+| Architecture | Triple |
+|---|---|
+| ARM64 | `aarch64-unknown-linux-android28` |
+| ARM32 | `armv7-unknown-linux-androideabi28` |
+| x86_64 | `x86_64-unknown-linux-android28` |

+# Integration
+
+Integrate Swift builds with Android tooling and frameworks
+
+## Gradle
+
+Add a custom Gradle task to invoke `swift build` and copy the resulting `.so` into `jniLibs/`:
+
+```kotlin
+tasks.register<Exec>("buildSwiftLibrary") {
+    workingDir = file("${rootDir}/swift")
+    commandLine("swift", "build",
+        "--swift-sdk", "aarch64-unknown-linux-android28",
+        "-c", "release", "--static-swift-stdlib")
+}
+```
+
+## Swift Package Manager
+
+```shell
+$ swift build --swift-sdk aarch64-unknown-linux-android28
+```

+# Porting Swift Packages to Android
+
+Adapt existing Swift packages to build and run on Android
+
+## Overview
+
+Many Swift packages build for Android with minimal changes. The typical process is: attempt a build, fix platform-specific code with conditional compilation, then test on a device.
+
+## Good candidates
+
+- Business logic, algorithms, data structures
+- Networking and API clients
+- Parsers, formatters, encoders/decoders
+- SQLite and other database access
+
+## Conditional imports
+
+```swift
+#if canImport(Darwin)
+import Darwin
+#elseif canImport(Android)
+import Android
+#elseif canImport(Glibc)
+import Glibc
+#endif
+```
