WatchTower - Observe OKHttp API Calls With Request And Response Details Right In Your Browser!
Add the dependencies to your project:
debugImplementation 'com.snakyapps.watchtower:interceptor-okhttp:1.1.0' releaseImplementation 'com.snakyapps.watchtower:interceptor-okhttp-no-op:1.1.0' // no-op dependency for non-debug build variants
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
Note: you should call
watchTower.shutDown() whenever your application/activity is terminating, which shuts down WatchTower-related services. If you're using it on Android, It's best to start and shut down the WatchTower inside an Android service (using
onDestroy of an Android Service)
- 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.
