Android WiFi Captive Portal

@gotucat

Hi, I reviewed the project and the main requirement is a small Android app that detects a captive portal on Wi-Fi and redirects the user to a designated URL. For Android App Development, I will implement this in Kotlin, using WiFiManager and network callbacks to detect the captive portal, then open the specified URL in a WebView or external browser. The deliverables will include a signed APK for testing, a full Android Studio project with clean, well-commented code, and a short README explaining build steps and where to change the redirect URL. Let’s discuss here now.

Hello, I will build the Android captive portal app using Kotlin with NetworkCallback and ConnectivityManager.ACTION_CAPTIVE_PORTAL_SIGN_IN to detect portal events, then redirect to your specified URL in a WebView. You get a signed APK, clean Android Studio project, and a README with the redirect URL config location. On a similar network utility app, using ConnectivityManager callbacks instead of polling kept detection reliable across Android 10 through 15. Questions: 1) Should the redirect open in an embedded WebView or the default browser? 2) What is the minimum Android version you need to support? Share the target redirect URL and I will have a testable APK within two days. Ready to start whenever you are. Kamran

Your captive-portal hand-off is exactly the kind of narrow, reliability-critical Wi-Fi work I enjoy. I'd build it in Kotlin using ConnectivityManager with a NetworkRequest scoped to TRANSPORT_WIFI, then register a NetworkCallback and watch onCapabilitiesChanged for NET_CAPABILITY_CAPTIVE_PORTAL alongside the VALIDATED flag — that's the standard, forward-compatible way to confirm a portal is present without brittle URL pinging. The moment one is detected on a freshly joined network, I route the user to your redirect URL, either in an in-app WebView or via an Intent to their default browser (your call). WifiManager covers SSID/state where it's needed. You'll get a signed APK for testing, the full Android Studio project with clean commented code, and a short README with build steps and the single constant to change for the redirect URL. I'll ship the first build quickly so you can test across versions, then tighten detection from your feedback — Android 11+ changed how portals are signaled, so real-device tuning genuinely matters here. One question: should the app catch portals passively in the background on any network join, or only fire while it's open? That choice drives the foreground-service and permission strategy on Android 13/14. Muhammad Saad

Hi, I can build this lightweight Android app in Kotlin using WiFiManager, ConnectivityManager, and NetworkCallback APIs to detect Wi-Fi connections and captive portal status reliably across modern Android versions. Once a captive portal is detected, the app will immediately open your configured URL in either a WebView or the default browser. I will keep the code clean, focused, and compatible with current Android permission and background execution requirements. You will receive a signed APK, the complete Android Studio project, commented source code, and a README showing how to build the app and update the redirect URL. I can also refine the detection flow based on your testing across different Android versions. Best, Justin

@denisSolution

Hi, I can build a lightweight Android app that catches captive-portal events and redirects users to the specified URL, staying compatible with newer Android releases by relying on WiFiManager and network callbacks. I did something similar for a hotel Wi-Fi solution where the detection had to work across Android 10-13, but the first version missed some edge cases with aggressive network policies. I'd approach this using Kotlin and the standard Android APIs because it keeps the app lean and future-proof, avoiding any vendor-specific hacks. The biggest improvement will come from careful testing on multiple Android versions to catch false positives. I'll keep the code clean, well-commented, and provide a build that’s easy to test and tweak before finalizing. The goal is a reliable captive-portal redirect that just works without complicating the user experience. If this fits your needs, I can start right now. Thanks, Denis.

Hi. To build this cleanly, I’ll use Android Studio with Kotlin, WiFiManager, ConnectivityManager, and network callbacks to detect Wi‑Fi joins and captive-portal state reliably on modern Android versions. I’ll route the user to your target URL through a WebView or external browser based on the flow you prefer, while keeping the hand-off fast and consistent. I’ll structure the app so the redirect URL is easy to change, and I’ll add the right manifest permissions and lifecycle handling to keep detection stable across releases. As a Senior Android Developer, I have mastered Kotlin, Java, Android networking APIs, and captive-portal handling, and have strong experience in Android utility apps, connectivity workflows, and release-ready APK delivery. I am sure I can deliver high-quality results within a short timeline for this small build. Let’s get in touch and discuss more. Thanks.

Hey, We will build your Android captive portal detector using ConnectivityManager's NetworkCallback with NET_CAPABILITY_CAPTIVE_PORTAL. This is more reliable than polling and works across Android 7+. For the redirect, we will register the callback at boot and on network change, then launch the target URL instantly in a WebView with JavaScript enabled for portal compatibility. A couple of quick things to confirm: 1) What is the minimum Android version you need to support? 2) Should the redirect URL be configurable from a settings screen or hardcoded? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Ready to start whenever you are. Faizan

@securetechs

Hi, is this meant to hook into Android's native captive portal detection (NetworkCallback + CAPTIVE_PORTAL capability) or do you want your own WebView screen popping up the moment the device joins the network? Either way the core challenge is the same: Android tries to auto-handle captive portals itself, so the app needs to listen for the network state change via ConnectivityManager, detect when internet access is blocked, then take over and load the portal page (or your own login screen) before the OS swallows it. I'd build this in Kotlin using NetworkCallback for the WiFi join event, a WebView (or custom UI if you want branding) for the login step, and proper session/cookie handling so it doesn't loop. Plan: first I'll test the detection logic against a couple different WiFi setups to confirm the trigger fires reliably, then build the core flow (detect join -> show portal -> confirm connected), then package a test APK for you to try on your own network before final handoff. Do you already have a captive portal server/backend running, or does the app need to include that piece too? Regards, Imtiaz, SecureTechs
