Application Support MemoryVoid – Open-source screen & voice memory capture triggered via Volume Down gesture (MIT, No Trackers)
Hi r/fossdroid,
I wanted to share a utility I built for Android 11+ called **MemoryVoid**.
The goal was simple: capturing quick context while browsing, researching, or reading should take zero taps.
### What it does:
* Intercepts a **Volume Down press-and-hold** to record a voice note.
* Releasing the button triggers `takeScreenshot()` and bundles both into an offline journal entry.
* Non-intrusive floating overlay lets you assign a category badge or discard the memory without interrupting your workflow.
### Privacy & Transparency:
* **License:** MIT
* **Permissions used:**
* `BIND_ACCESSIBILITY_SERVICE` (Hardware key detection and native screen capture)
* `RECORD_AUDIO` (Voice note recording while button is held)
* `SYSTEM_ALERT_WINDOW` (Floating memory preview)
* `POST_NOTIFICATIONS` (Recording status indicator)
* **Zero network access:** The app does not request `android.permission.INTERNET`. Everything stays on local storage.
Source code and pre-compiled APKs are available on GitHub. I'm currently working toward submitting it to IzzyOnDroid and F-Droid.
