Proguard Warnings

[Nolanus]

When creating a release apk of an app that uses RxBolts, the following proguard warnings appear:

Warning: rx.bolts.TaskObservable: can't find referenced class java.lang.invoke.MethodHandles$Lookup
Warning: rx.bolts.TaskObservable: can't find referenced class java.lang.invoke.MethodHandles
Warning: rx.bolts.TaskObservable$$Lambda$1: can't find referenced class java.lang.invoke.LambdaForm$Hidden

Hi @yongjhih,

I'm very much facing this same issue when trying to use ProGuard on the latest rxParse:

    compile 'io.reactivex:rxandroid:1.2.1'
    compile 'io.reactivex:rxjava:1.2.0'
    compile 'com.infstory:rxparse:2.0.2'

The build throws this warning:

Warning:rx.bolts.TaskObservable: can't find referenced class java.lang.invoke.MethodHandles$Lookup
Warning:rx.bolts.TaskObservable: can't find referenced class java.lang.invoke.MethodHandles

I'm currently using these ProGuard rules for RxJava:

-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;
}

I'm not sure why your ProGuard config doesn't work but a quick search shows this StackOverflow question, maybe this is the problem?

Sorry, I mistook adding proguard file:

I can confirm this is the correct rule. I did add this into the main proguard file shortly after asking this question and it works perfectly. If you add this into the library, I can just use this instead.

Thanks a gain for your prompt reply.

Sorry @yongjhih, I think you need to update RxParse to reference this commit as I don't use RxBolts directly and with version 2.0.2 of RxParse, this error still show up.

@vxhviet, I've updated RxParse to 2.0.3 you can try.
