HorizonOS Floating WebView Overlay

@Herculesz

Hi, this is a low-level Android reverse-engineering problem more than a standard app build, and the rooted HorizonOS setup makes it feasible to inspect how the stock overlay is actually being admitted by the system. The real engineering risk is not the WebView itself; it is reproducing the trust boundary around the private overlay path without introducing crashes, permission faults, or package verification failures. I usually structure work like this in two phases: first decompile and trace the stock overlay APK to map services, permissions, bind points, and any signature or package-name assumptions; then re-implement the minimum viable overlay path with a clean URL injection mechanism and repeatable install flow. The Android/Gradle deliverable is straightforward once the acceptance path is understood. The closest prior work here is Custom Feature Development & Integration, where I stepped into an existing system, performed a code walkthrough, isolated implementation constraints, and delivered documented changes cleanly. Python Bug Localization Using Transformer Models is also relevant on the investigation side because it reflects how I approach opaque behavior systematically. I recommend separating discovery, admission checks, and overlay rendering so failures are isolated early. If useful, I can sketch the verification surface and likely failure points before build-out. Thanks, Hercules

Hi I can deliver a safe, compliant HUD overlay for HorizonOS that uses a WebView in an always-on-top window. The app will load a URL specified at runtime and present it without back, forward or refresh controls. I will implement it using public Android APIs to ensure reliability and easy installation on your device. The overlay will stay above all apps, be resizable to match the stock HUD position, and use a simple config mechanism to set the target URL (local file or intent extra). Deliverables: full source with Gradle/Android Studio build instructions; a signed APK; a short write-up detailing the public API surface, how the window behaves, and any verification considerations. I will not exploit private APIs or bypass signature checks, focusing instead on a robust, maintainable solution that mirrors the HUD visuals while staying within platform rules. If you want runtime URL changes, I can add a minimal settings page or ADB toggle. Best, Justin

@techsty2014

I can help with this, We will reverse engineer the stock overlay APK, identify the private library calls and signature checks, then build a new APK that replicates the floating WebView HUD on your rooted HorizonOS device. Since USERDEBUG is active, we will hook into the system compositor layer directly. We will patch signature verification at the PackageManager level rather than resigning the framework. A couple of quick things to confirm: 1) Which HorizonOS version is running on the device? 2) Do you need the overlay to be resizable, or is a fixed position acceptable? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Send me a message and we can go over the details.

@aprkdream

Hi, I understand that you need a developer to replicate the floating overlay functionality on HorizonOS, similar to Meta's system-level "floating overlay". I'll break down the task into manageable chunks and provide a clear approach. To start, I'll analyze the stock overlay APK, which is unencrypted and easily decompilable. Using this, I'll identify the required libraries, services, and signature checks necessary for the new APK to be accepted by the system. Next, I'll re-implement the floating interface using the same libraries and services, ensuring that the new APK meets the system's requirements. This will involve bypassing or mimicking the necessary pack checks to maintain compatibility. My background in Android app development, including expertise in Java, Kotlin, and Mobile Development, positions me well for this task. I've also worked on similar reverse engineering projects in the past, which will aid in identifying the necessary libraries and services. The outcome of this project will be an independent app that displays a WebView on top of any screen, loading any URL specified at runtime without back, forward, or refresh controls. To confirm, I have a few questions: What is the expected behavior for the floating overlay when the user navigates to a new URL? Are there any specific security requirements or restrictions for the WebView? I'm confident that I can deliver a reliable and efficient solution for this project. I'll provide regular updates and ensure that the work is completed to the highest standards.

@serviceaxisgroup

Hi, I can help with replicating Meta-style system floating WebView HUD on HorizonOS, so your URL loads instantly above all activities without navigation chrome. I’ll decompile the stock overlay APK, map the required services/libraries/signature checks, then reimplement the same floating behavior in a standalone Java app using a simple runtime-configured URL (intent extra or settings). To reduce risk, I’ll keep changes minimal, add logging, and verify installation/launch on-device step-by-step with a short technical write-up. Which HorizonOS version/build are you on, and do you prefer URL control via intent extra or a tiny in-app settings page? If you share the device build and overlay APK, we can start right away.

@haseebs74

Hi, HorizonOS floating WebView overlay by reverse engineering the stock overlay APK and reimplementing the private API calls on a rooted USERDEBUG device. Low-level Android work and private API tinkering is exactly what I enjoy. Here is my approach. Decompile the stock overlay APK using jadx to map the private API calls, required libraries, services, and any signature or package verification checks. Reimplement the floating overlay using the same system libraries so the new APK is accepted without modification. On a rooted USERDEBUG build, signature verification can be bypassed via Magisk modules or by patching the relevant verification call in the system, whichever is cleaner for your specific HorizonOS version. The WebView will load any URL set via a config file or intent extra, display with no navigation chrome, and stay on top of all activities at a fixed or resizable position matching the stock HUD behaviour. Deliverables: full Android Studio source code with Gradle build instructions, signed installable APK, and a technical write-up explaining every private API call used and how verification was handled. Acceptance: overlay on top of all activities, loads any URL instantly, no navigation chrome, no crashes or permission errors. Timeline: 7 to 12 days. Share the stock overlay APK and your HorizonOS version and I will assess the verification mechanism before confirming the final price.
