APKLife

APKLife Native (Variant B: Offline Flask-in-APK) — EN

This variant runs Flask inside APK (Chaquopy) and opens WebView on http://127.0.0.1:5000.

Requirements

• Android Studio
• JDK 17
• Android SDK + build tools
• Internet access for initial Gradle/Chaquopy dependency download

Build debug APK

Linux/macOS

cd android_native
./gradlew :app:assembleDebug

Windows (CMD/PowerShell)

cd android_native
gradlew.bat :app:assembleDebug

Output APK

• android_native/app/build/outputs/apk/debug/app-debug.apk

Runtime flow

1. MainActivity starts Chaquopy Python runtime.
2. Calls android_entry.start_server().
3. Flask runs in background thread on 127.0.0.1:5000.
4. WebView loads local URL after readiness check.

Notes

• First build can be slow due to dependency downloads.
• Python app files are synced before build by Gradle task.
