Assign one app to the Android accessibility button or shortcut
About this app
Accessibility Button Launcher lets you assign one installed app to the Android accessibility button or accessibility shortcut that is already built into Android.
Because it uses the operating system's built-in accessibility trigger, the integration stays simple and low-friction. You use the same system control Android already provides instead of a custom overlay, floating tool, or extra launcher layer.
When the accessibility trigger is used, the app launches only the app you selected. This keeps the experience direct and lightweight while working with the platform behavior that Android already supports. If the saved app is no longer available, the app explains what needs to be fixed instead of failing silently.
What it does: - Assigns one launchable app to the accessibility button or shortcut - Leverages Android's built-in accessibility button for a native-feeling integration - Guides you through the initial setup - Helps recover when the accessibility service is disabled after an app update - Includes background-protection guidance for devices that aggressively stop accessibility services
Privacy and permissions: - No analytics, advertising, or crash reporting - No cloud sync and no network data collection - Settings are stored only on your device - The accessibility service is used only to respond to the accessibility button or shortcut
The app is open source and built for people who want a simple, focused way to launch one app from the system accessibility trigger.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.pedronveloso.a11ybutton is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for Accessibility Button Launcher, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Accessibility Button Launcher, and a listing is removed when the evidence for it stops holding up.
