8. Cloud Debug Logs (recommended)
Enabled crash/error reporter into the app during build. Once enabled and rebuilt, the app reports its own crashes straight to this server over the internet from ANY Android phone it's installed on — no USB, no ADB, no network configuration, and no port forwarding required.
Choose either the lightweight Debugger Only App (log-analyzer.apk) to receive crashes & logs, or the Full Suite App (APKTOOL Studio) (apktool-studio-app.apk) with full features and mobile interface to build, decompile, edit, sign, and view logs on Android instead of web.
Scan QR code or tap button to download log-analyzer.apk for crash, exception, and log tracking.
Scan QR code or tap button to download apktool-studio-app.apk with complete mobile UI & features.
Reinstall the rebuilt APK or open the Debugger Only App / APKTOOL Studio App and tap Check for Update to receive the latest logging changes.
Open the Debugger Only App or APKTOOL Studio App on your Android device, tap Scan QR Code, and point your camera at the QR code below. Pairing connects your app to this server in seconds to stream crash reports, logs, and live network requests over the internet.
Camera unavailable? Copy this pairing code and paste it into the Connect screen inside the Debugger Only App or APKTOOL Studio App.
9. Developer Tools
HttpURLConnection, OkHttp, Retrofit, and WebView fetch()/XHR calls). If this stays empty, re-check the "Cloud Debug Logs" step to ensure hookable call sites were enabled before rebuilding.
Log.d/i/w/e/v calls captured by the injected DebugLog hooks, plus fatal crash reports) will stream here in realtime once the rebuilt app is installed and launched on a device.
Connect an Android device via USB (with USB debugging enabled) or wireless ADB to this server/PC, install the APK directly, and watch its logs in realtime.
On the phone: Settings > Developer options > Wireless debugging > turn it on, note the IP:port shown there (both devices must be on the same Wi-Fi/network). Some Android versions require pairing first with a pairing code - if connect is refused, use "Pair device with pairing code" on the phone and pair from a terminal first, then connect here.
