Cachelio

Cachelio by NullMargin is an Android browser that helps you find videos while you browse, download them for offline use, and watch them privately on your device.

What you can do

• Browse the web in a built-in browser with a local start page (Baidu, Bing, and Google)
• Detect videos automatically as pages play or load media
• Download for offline use — regular video files and HLS/M3U8 streams, with resume if a download is interrupted
• Manage your library in Files — search, sort, share, and group downloads
• Watch in the app with an in-app player and optional auto-play next

Privacy design

Cachelio keeps your private library under your control on this device.

• Hide media in Files so it stays out of the normal library view
• Privacy password (optional) protects Privacy settings and unlocking the current session
• On-device only — your password verifier is stored only on this device. There is no cloud account, password reset, or recovery. If you forget it, you must clear the app data
• Session unlock — lasts for the current app session only and locks again when the app process restarts. While unlocked, hidden files are shown, and bookmarks added while unlocked are only visible until you unlock again. Bookmark toolbar actions stay available when locked; only private bookmark entries are hidden

Get the app

Official releases are published on GitHub Releases as cachelio-<tag>.apk (for example cachelio-v2.0.3.apk).

For development builds, install the latest debug APK from the GitHub Actions artifact cachelio-debug-apk-<branch> (workflow: Cachelio Debug APK). Pushes to any branch build that branch.

Cachelio uses package id com.holeintimes.vbrowser, so it installs as an update over previous VBrowser builds and keeps your existing downloads and settings.

For developers

Requires JDK 17+, Android SDK (compileSdk 35), and an environment that can run Android aapt2 (typically x86_64 Linux, macOS, or Windows via Android Studio).

echo "sdk.dir=$HOME/Android/Sdk" > local.properties
./gradlew :app:assembleDebug
./gradlew :app:installDebug

Or open the project in Android Studio (Ladybug+) and sync.

CI: .github/workflows/cachelio-debug-apk.yml builds assembleDebug on push (any branch), PR, and workflow_dispatch, and uploads cachelio-debug-apk-<branch>. .github/workflows/cachelio-release-apk.yml builds a signed assembleRelease APK and attaches it when a GitHub Release is published.
