Kommute

Kommute is an Android library to observe your apps network traffic while debugging.

About

Kommute lets you observe the network traffic of your app for debugging purposes. It shows all connections from your OkHttp calls and displays various information like headers, request and response bodies.

Kommute uses Androids Bubble Api to show the network traffic in a hovering bubble, which makes it easily accessible while navigating through your app. The network traffic can be observed as long as the app lives, even while it is in the background.

Download

Kommute is a debug tool. It comes with a no-op version, which should be used in release builds. See maven-central tag at the top for latest version.

dependencies {
    debugImplementation 'com.sebastianneubauer:kommute:latest-version'
    releaseImplementation 'com.sebastianneubauer:kommute-no-op:latest-version'
}

How to use

Add Kommutes Interceptor to your OkHttp instance.

val kommuteInterceptor = Kommute.getInstance().getInterceptor()

val httpClient = OkHttpClient.Builder()
        .addInterceptor(kommuteInterceptor)
        .build()

Get the Kommute instance and call start to show its notification. For example in your apps onCreate method. Make sure your app has notifications enabled on Android 13+.

Kommute.getInstance().start(context)

Click the expand icon on the notification to open Kommutes Bubble.

The consumer app needs to enable coreLibraryDesugaring. More info here.

Images and Gifs

Like regular API calls, Kommute can show calls to image and gif links and display the returned image/gif. To enable this behaviour, your image loading library needs to use the same OkHttpClient you use for networking. The following example shows the setup with Coil.

Get your pre-built OkHttpClient, which has Kommutes Interceptor applied and remove its cache. Then add it to your ImageLoader. See DiskCache and Custom OkHttpClient for more info.

val okHttpClient = getOkHttpClient().newBuilder().cache(null).build()

ImageLoader.Builder(context)
        .okHttpClient(okHttpClient) //add your OkHttpClient
        .components {               //add support for gifs
            if (SDK_INT >= 28) {
                add(ImageDecoderDecoder.Factory())
            } else {
                add(GifDecoder.Factory())
            }
        }
        .build()

After providing the Imageloader through the ImageLoadingFactory, it is ready to use with Coils ImageRequest or AsyncImage.

Note: If your ImageLoader uses a cache, subsequent requests to the same image might not be shown in Kommute.
