[Mohamed Alouane]

I just updated to Android O and this error occured :

I Am using rxlocation:1.0.3 and RxJava 2

i also have this problem..

[Johan Reitan]

It seems to be a problem with the new Android Gradle plugin 3.0.0 clashing with Retrolambda. Updating the plugin and removing Retrolambda from the library solves the problem.

[Patrick Löwenstein]

Please use Android Studio 2.3.3 for testing with Android O. When Android Studio 3.0.0 stable is released, I'll update the library to remove Retrolambda, since the Android Gradle plugin then can consume Java 8 libraries.

[Mohamed Alouane]

Thank for the reply Patrick , I wonder if we can have 2 branches : stable and preview?
Thanks.

[Patrick Löwenstein]

There are no plans to support preview versions of Android Studio. Usually, preview versions don't make problems though. The problem here are changes to the way Java 8 stuff is supported in Android Studio in the future.

[stefan-zobel]

This is probably caused by a bug in the Gradle Java 8 language feature desugaring that is tracked in https://issuetracker.google.com/issues/62456849

desugar seems to blindly rename the synthetic methods in a class file if their name starts with lambda$ (appending the owner class name) regardless of whether a reference to that method already exists in the bytecode (and that reference doesn't get renamed too!).

When the code path hits such a reference at runtime the obvious result is a NoSuchMethodError because a method with that name doesn't exist anymore.

is updated now to android studio 3 stable

[Patrick Löwenstein]

Removed Retrolambda in v1.0.4.
