One Tap Recorder: what it solved and how

An Android screen recorder you start from a home-screen widget: 4K at 60 FPS, device audio and microphone, no accounts, no ads, no network access.

The thinking

One decision worth defending

01
Problem
Android can record the screen, but getting there means Quick Settings, finding the tile, choosing the audio source and confirming, every time.
02
Decision
Put the recorder on the home screen as a resizable widget, and step down through 4K/60, 4K/30, 1080p/60 and 1080p/30 instead of failing when the encoder cannot keep up.
03
Why it holds
Every tap you remove is a recording that gets made. A fixed fallback order means a recording always starts, at the best quality the phone can hold.

What it includes

Three responsive widget layouts (1x1, 2x1 and 2x2) that change as you resize them
Device audio and microphone mixed into one AAC track in real time
A Quick Settings tile and an optional double-press Volume Up shortcut
A persistent notification with a Stop action, and the MP4 saved to the gallery
No accounts, no ads, no analytics and no network access

If you are building something similar

Design the fallback before the failure. A slightly worse recording beats no recording, and the user should not have to configure that.
