RxJava，Jack＆amp; Jill Java 8 Support and Proguard

我禁用了Jack＆amp; Jill来自我的gradle文件并为lambda支持添加了复古lambda插件。问题解决了！

proguard-rules.pro 应包含以下RxJava规则：

-dontwarn sun.misc.**

-keepclassmembers class rx.internal.util.unsafe.*ArrayQueue*Field* {
   long producerIndex;
   long consumerIndex;
}

-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef {
    rx.internal.util.atomic.LinkedQueueNode producerNode;
}

-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueConsumerNodeRef {
    rx.internal.util.atomic.LinkedQueueNode consumerNode;
}

问题

我正在使用Observable's fromCallable函数来生成测试数据。代码运行良好没有proguard ，但当我激活proguard 时，Subscription's onNext函数不会调用。

可观察的电话

public void loadNearbyUserEvents() {
    Log.w(TAG, "loadNearbyUserEvents");
    try {
        getMvpView().showProgress();

        Subscription subscription = dataManager.getEventImplementer().getNearbyUsersEvents()
                .observeOn(AndroidSchedulers.mainThread())
                .subscribeOn(Schedulers.io())
                .subscribe(getSubscriber());

        subscriptions.add(subscription);

        Log.w(TAG, "aaaa");

    } catch (Exception e) {
        e.printStackTrace();
        getMvpView().showError(e.getMessage());
        getMvpView().hideProgress();
    }
}

private Subscriber<List<Event>> getSubscriber() {
    return new Subscriber<List<Event>>() {
        @Override
        public void onCompleted() {
            Log.w(TAG, "onCompleted");
        }

        @Override
        public void onError(Throwable e) {
            Log.w(TAG, "onError");
            e.printStackTrace();
        }

        @Override
        public void onNext(List<Event> events) {
            Log.w(TAG, "size of list : " + events.size());
            getMvpView().hideProgress();

            if (events.size() == 0) {
                getMvpView().showEmpty();
                return;
            }

            getMvpView().showEvents(events);
        }
    };
}

EventImplementer的getNearbyUserEvents

@Override
public Observable<List<Event>> getNearbyUsersEvents() {
    return Observable.fromCallable(() -> EventProducer.produce(20));
}

以上代码在没有proguard的情况下运行良好。

    # Add project specific ProGuard rules here.

我的代码出了什么问题？为什么只有onCompleted函数可以工作，但onNext和onError函数不会调用？

注意：当我使用Observable.just(() -> EventProducer.produce(20))功能时，它正常工作。

嘿，使用RxJava我使用这个规则

# rxjava
-keep class rx.schedulers.Schedulers {
    public static <methods>;
}
-keep class rx.schedulers.ImmediateScheduler {
    public <methods>;
}
-keep class rx.schedulers.TestScheduler {
    public <methods>;
}
-keep class rx.schedulers.Schedulers {
    public static ** test();
}

-keepclassmembers class rx.internal.util.unsafe.*ArrayQueue*Field* {
   long producerIndex;
   long consumerIndex;
}

-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef {
    rx.internal.util.atomic.LinkedQueueNode producerNode;
}

-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueConsumerNodeRef {
    rx.internal.util.atomic.LinkedQueueNode consumerNode;
}

也许会有所帮助。
