A first Pithos app for phones. It runs the browser app in a WebView and answers the page's own files from the APK under the gateway's origin, so the page stays the same-origin client it was designed as and the files are still encrypted and decrypted in the page. What the phone adds: "Save to Pithos" in other apps' share menus (the files wait in a bar until a folder is open), downloads written to the Downloads folder, the system file picker for uploads, and outside links opened in the phone's browser. The browser app learns the two hooks (window.PithosAndroid) and says plainly when a browser is too old to sign in, instead of a bare "NotSupportedError".

# Builds Pithos for Android with the bare Android SDK: no Gradle, no AGP.
|
|
# Toolchain: JDK 8 + build-tools 30.0.3 + platform android-30.
|
|
# The page is Pithos/web, copied into the APK's assets at build time.
|
|
# Usage: powershell -File build.ps1 -> build\pithos-debug.apk (debug key)
|
|
# powershell -File build.ps1 -Release -> build\pithos-v<version>.apk (release key)
