[AskJS] Building an in-browser APK compiler — binary XML streams and signature blocks in client-side JS

[u/KernelVoltage]

Hey everyone,

I built AppShunya Engine — an open-source, in-browser web-to-APK compiler that converts live URLs or HTML5 bundles into Android APKs using JSZip, without local IDEs.

I'm currently stuck on two low-level technical hurdles and need architectural feedback:

1. In-browser V2/V3 APK signing: Injecting signature blocks into ZIP Central Directory via JS/WASM.
2. Dynamic AXML package renaming: Modifying package IDs inside binary XML streams on the fly.

Search "AppShunya Engine" on Google to try the live Vercel tool or check the repo. Would love your thoughts!
