QrDPC

A small Android app that reads a QR code encoding Android Managed Configuration (App Restrictions) values and pushes them to a target app — no more clicking through a DPC's UI by hand.

Motivation

Testing an app that reads its configuration from Android Managed Configuration (Intune App Restrictions, or the equivalent RestrictionsManager values pushed by any EMM/DPC) usually means opening a DPC app such as TestDPC, navigating to its "Managed configurations" screen, and manually re-entering values every time they need to change. There's no simple adb command for this, and the TestDPC UI is easy to get wrong (unsaved edits are lost if you navigate away before hitting the outer save button).

QrDPC removes that friction: encode the restrictions bundle you want as a QR code, scan it with this app, and it applies the values directly — repeatable, shareable, and scriptable (any QR code generator can produce the input).

Status

QR scanning (CameraX + ML Kit Barcode Scanning) and applying the decoded restrictions bundle via the delegated DevicePolicyManager.setApplicationRestrictions call are implemented. A companion web-based QR config generator builds the QR codes QrDPC scans — fully offline, no server involved.

Requirements

• Android 8.0 (API 26) or later.
• The active Device Policy Controller must delegate the APP_RESTRICTIONS scope to this app's package (io.github.fcastell.qrdpc) for the target app you want to configure — QrDPC does not act as its own DPC. See docs/installation.md for a full setup guide, including installing TestDPC and granting this delegation.

Building

./gradlew :app:installDebug

See docs/ for installing on a device and setting up a DPC to delegate to QrDPC.

Development setup

This repo uses lefthook to auto-format staged Kotlin files before each commit. After cloning, install it once (e.g. brew install lefthook on macOS) and wire up the git hooks:

lefthook install
