Add visibility of proguard rules to README or wiki please

Are there examples of proguard rules that will work with minifyEnabled set to true? I’m currently getting:

 java.lang.NoSuchMethodError: No virtual method doOnSubscribe(Lrx/functions/Action0;)Lrx/Observable

@jaredsburrows You’re right, thanks for noticing. Seems like a dumb copy-paste error… Anyway, the proper settings should be:

-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;
}

On my code base (and yours too apparently), BaseLinkedQueueProducerNodeRef and BaseLinkedQueueConsumerNodeRef classes altogether were stripped away by Proguard anyway so that no problem arose. For anyone whose code ended up BaseLinkedQueue though, it would have probably thrown at runtime.

@artem-zinnatullin Oh yes, forgot to add that - only switching Unsafe off on these problematic device - OS combinations.

@eranpolo Thanks the extra info. I’m still trying to get my hands on an affected device to get to the bottom of this.

Edit: for reference, our current naive workaround for the Samsung-issue:

if (Build.VERSION.SDK_INT == Build.VERSION_CODES.LOLLIPOP && "samsung".equalsIgnoreCase(Build.MANUFACTURER)) {
    System.setProperty("rx.unsafe-disable", "True");
}
