A network proxy library to intercept and mock response from OkHttp

Getting started

In your root build.gradle:

allprojects {
    repositories {
        // Other configurations ...
        jcenter()
    }
}

In your app/build.gradle:

dependencies {
  debugImplementation 'com.github.nongdenchet:networkproxy:0.7.0'
  releaseImplementation 'com.github.nongdenchet:networkproxy-no-op:0.7.0'
}

Since OkHttp now requires Android 5.0+ (API level 21+) and Java 8+, we need to add:

android {
  // other configuration...
  defaultConfig {
    // other configuration...
    minSdkVersion 21
  }

  // other configuration...
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

Add the Interceptor to your OkHttp builder:

new OkHttpClient.Builder()
  // other configuration...
  .addInterceptor(NetworkProxy.interceptor())
  // other configuration...
  .build();

Using with desktop app

  • In your Application class:
public class ExampleApplication extends Application {

  @Override public void onCreate() {
    super.onCreate();
    NetworkProxy.init(this, 9000); // 9000 is the port that is later use to connect from Desktop app
    // Normal app init code...
  }
}
  • Connect your device with adb and run adb forward tcp:8000 tcp:9000 to connect port 8000 of your computer and port 9000 of your device
  • We provide a client desktop app to use and interact with pending response

Using without desktop app

  • In your Application class:
public class ExampleApplication extends Application {

  @Override public void onCreate() {
    super.onCreate();
    NetworkProxy.init(this);
    // Normal app init code...
  }
}
  • To mock data from a pending response
adb shell "am broadcast -a com.rain.networkproxy.INSTRUCTION -n [YOUR_APP_PACKAGE]/com.rain.networkproxy.NPReceiver \
    --es data '{"id": "0", "status": 200}' \
    --es body '"'{"id": 1, "title": "hello"}'"'"

"id": "0" is the pending response id. You can get it through the UI or from Logcat (Put NetworkProxy as filter to see the logs)
