Fresco 2.1.0 comes with tons of improvements, including a Java-only Fresco version.

Highlights

• A Java-only Fresco version. See below for Gradle setup. Note: If you display animated GIFs, you can use animated-gif-lite instead of animated-gif for Java-only GIF support.
• SoLoader is now optional again. We've worked on a new NativeLoader interface to load native code on Android. Now, with Fresco 2.1.0 all the changes are available for people to use, see below for the Gradle setup. If you want to employ a custom native loading mechanism, just implement a NativeLoaderDelegate and call NativeLoader.init(yourDelegate) before Fresco is initialized.
• New ProducerListener2 and RequestListener2. They give you significantly more flexibility since they allow you to access more image information.
• The possibility to pass down the UI component ID (e.g. Drawee ID / Vito ID) through the whole image pipeline, which, in combination with listeners above, can for example be used for debugging or logging.
• A new memory type for encoded images and byte buffers: Ashmem. Now you can either use Java memory, native memory or Ashmem.
• Faster circular native rounding.
• Improved concurrency handling for deferred releasing - and much more.
• You can look at the full changelog here.

Java-Fresco Gradle setup:

implementation('com.facebook.fresco:fresco:2.1.0') {
    exclude group: 'com.facebook.soloader', module: 'soloader'
    exclude group: 'com.facebook.fresco', module: 'soloader'
    exclude group: 'com.facebook.fresco', module: 'nativeimagefilters'
    exclude group: 'com.facebook.fresco', module: 'nativeimagetranscoder'
    exclude group: 'com.facebook.fresco', module: 'memory-type-native'
    exclude group: 'com.facebook.fresco', module: 'imagepipeline-native'
}

Custom SoLoader Gradle setup:

implementation('com.facebook.fresco:fresco:2.1.0') {     
      exclude group: 'com.facebook.soloader', module: 'soloader'
      exclude group: 'com.facebook.fresco', module: 'soloader'    
 }

Breaking Dependency Change

We bumped the major version since Fresco is now using AndroidX support libraries. If you are still using the previous support library, please use version 1.13.0 until you've migrated to AndroidX.

New Flipper Images Plugin

We've open sourced our Flipper images plugin, which makes it easy for you to debug images within your application. Take a look at the Flipper documentation here: https://fbflipper.com/docs/features/images-plugin.html It also allows you to track unclosed CloseableReferences if you're using the image pipeline directly.

Fixes and Improvements

Highlights:

• Added explicit color management (51efaa75f410a390566f72596099c35d85a42216). See #2323 for more information.
• Added API to get the size of the disk cache.
• Fix scaling up image with RoundingParams.
• Prevent Fresco from crashing for certain invalid GIFs.
• Added local content URI support for fetching encoded images.
• Added CloseableReference leak tracking. You can hook up your own listener to track unclosed references.
• Video thumbnails: generate video thumbnail from content provider when we cannot get file path.
• Updated the Showcase sample app to enable the Flipper images plugin and started using Kotlin.
• Display Image URI in Fresco's debug overlay.
• Improved image origin listener accuracy.
• Added caller context verification to the ImagePipeline. You can now check whether proper image attribution (caller context) is set.

Thanks to the following for their pull requests which are included in this release: @otopba, @lpy and @kexuejin

• Added leak tracking for CloseableRefererences. You can hook up your custom leak handler for unclosed CloseableReferences which is triggered when a reference is GCed without being explicitly closed.
• You can also use the new Flipper images plugin (https://github.com/facebook/flipper) to track these leaks.

• Open sourced our Fresco Flipper plugin.
• Updated target SDK to 28.
• Replaced gnustl_static with c++_static.
• Updated various dependencies.

Version 1.8.1 is a bug-fix release following the main 1.8.0 release. In particular, it addresses the following issues:

• Fresco's SoLoader configuration no longer crashes with certain pro-guard configurations (issue: #2039)
• In previous versions WebP image might fail to load in certain configurations (commit: https://github.com/facebook/fresco/commit/06fe3719a3a3c659438b6c25a8008945e67156a0)
