Frodo is an android library inspired by Jake Wharton's Hugo, mainly used for logging RxJava Observables and Subscribers outputs on the logcat. It generates and weaves code based on annotations only on debug versions of the application where the plugin is applied, for instance, it is safe to persist any Frodo annotation in the codebase.

• @RxLogObservable: Annotated methods which return rx.Observables will print the following information on android logcat when emitting items:

    @RxLogObservable
    public Observable<List<MyDummyClass>> list() {
        return Observable.just(buildDummyList());
    }

@RxLogSubscriber
public class MySubscriberBackpressure extends Subscriber<Integer> {

    @Override
    public void onStart() {
        request(40);
    }

    @Override
    public void onNext(Integer value) {
        //empty
    }

    @Override
    public void onError(Throwable throwable) {
        //empty
    }

    @Override
    public void onCompleted() {
        if (!isUnsubscribed()) {
            unsubscribe();
        }
    }
}

buildscript {
  repositories {
    jcenter()
  }
  dependencies {
    classpath "com.fernandocejas.frodo:frodo-plugin:${latest_version}"
  }
}

apply plugin: 'com.android.application'
apply plugin: 'com.fernandocejas.frodo

Debugging RxJava on Android

Aspect Oriented Programming in Android

Presentation AOP + Frodo

1 - Multi module setup (application + android library) will not log annotated methods/classes from Android Library Module but will do it on Android Application Module. The reason behind this, is that the Android Gradle Plugin will build all Android Libraries as release versions, for instance, Frodo is not able to weave any code on the annotated methods/classes (Remember that only weaves in debug versions). There is a workaround for forcing debug versions of your Android Libraries (just be careful in case this is forgotten and you end up shipping a version of your app with RxJava Logging enabled) by adding this line in your build.gradle file:

android {
  defaultPublishConfig "debug"
}

Here are some useful Gradle commands for executing and installing the library:

• ./install_frodo.sh - One time execution command for installing frodo library and dependencies.
• ./gradlew installFrodoApi - Installs Frodo Api dependencies.
• ./gradlew installFrodoRuntime - Installs Frodo Runtime dependencies.
• ./gradlew installFrodoPlugin - Installs Frodo gradle plugin.
• ./gradlew installFrodoAndroidSample - Build and installs everything plus android application sample.
• ./gradlew runUnitTests - Run unit tests.
