WatchTower - Observe OKHttp API Calls With Request And Response Details Right In Your Browser!

Download

Add the dependencies to your project:

debugImplementation 'com.snakyapps.watchtower:interceptor-okhttp:2.0.2'
releaseImplementation 'com.snakyapps.watchtower:interceptor-okhttp-no-op:2.0.2' // no-op dependency for non-debug build variants

Setup

Add the interceptor to your OKHttp Client

        val retrofit = Retrofit.Builder()
                        .client(
                            OkHttpClient.Builder()
                            .addInterceptor(WatchTowerInterceptor())
                            .build()
                        )
                        // ...
                .build()

        WatchTower.start(WebWatchTowerObserver(port = 8085)) // in Application class

(Optional for Android) Add the Android artifact

You can add the following artifact to see the requests right in your notification area. You can collect from a Flow<Notification> and notify the notification manager.

debugImplementation 'com.snakyapps.watchtower:android:2.0.2'
releaseImplementation 'com.snakyapps.watchtower:android-no-op:2.0.2' // no-op dependency for non-debug build variants

   someScope.launch {
                WatchTowerAndroid.notificationFlow(application, serverPort).collect {
                    notification ->
                    (getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager).notify(999991, notification.build())
                }
            }

To turn off notifications, you can cancel the coroutine Job (e.g. launch).

Features

• Track and observe all API calls made through OKHttp's client
• GET, POST, PUT, DELETE, PATCH methods
• Query parameters, request and response body and headers
• Response success and failure status, size, date and latency
• Adjustable port for the server and the websocket server
• API call history, even If no browsers were open
• Search in the URLs of all requests
• Fully responsive UI
• Fully extensible

Observing the events using your browser Connect the device that is running the app to the same network that you want to observe the data. If you are on a WiFi, both devices should be connected to the same WiFi so they can communicate with each other. After running your application, you can navigate to http://yourip:8085/ and view the network calls. If you don't know what yourip is, It will be printed out to the console with the message of WatchTower started, listening on ... when Watchtower.start() is called.

Observing emulator events in your computers browser If your running WatchTower in an emulator you need to forward both server and websocket ports from the emulator to your local computer. For example if WatchTower is running on port 8085 you would need to run:

adb forward tcp:8085 tcp:8085
adb forward tcp:5003 tcp:5003

The forward of port 5003 is used for the websocket connection.
