Version 1.0.0
Version 1.0.0
October 9, 2019
androidx.concurrent:concurrent-futures:1.0.0 is released. Version 1.0.0 contains these commits.
Important features of 1.0.0
androidx.concurrent:concurrent-futures:1.0.0 provides CallbackToFutureAdapterclass, a minimalistic utility that allows to wrap callback based code and return instances of ListenableFuture. It is useful for libraries that would like to expose asynchronous operations in their java APIs in a more elegant way than custom callbacks, but don’t do enough multithreading heavy-lifting to take a dependency on full guava or rx java due to library size concerns.
Version 1.0.0-rc01

androidx.concurrent:concurrent-futures:1.0.0-rc01 is released with no changes from 1.0.0-beta01. The commits included in this version can be found here.
Concurrent-ListenableFuture Version 1.0.0-beta01
May 30th, 2019
androidx.concurrent:concurrent-listenablefuture:1.0.0-beta01 and androidx.concurrent:concurrent-listenablefuture-callback:1.0.0-beta01 are released. The commits included in this version can be found here.
These libraries provide a standalone equivalent to Guava’s ListenableFuture interface and an adapter for converting callbacks.
The previously-released androidx.concurrent:concurrent-futures artifact, which provided a similar adapter and included the com.google.guava:listenablefuture artifact, may be problematic for developers using toolchains -- such as Android Gradle Plugin 3.4.0 -- with strict dependency resolution matching. Developers who do not rely on the full Guava library are advised to switch to androidx.concurrent:concurrent-listenablefuture-callback.
Version 1.0.0-beta01
May 7, 2019
