libjpeg-turbo
SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface. -

Zipkin
Distributed tracing system to gather timing data
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data. If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration. Some interesting data will be summarized for you, such as the percentage of time spent in a service, and whether or not operations failed. The Zipkin UI also presents a Dependency diagram showing how many traced requests went through each application. This can be helpful for identifying aggregate behavior including error paths or calls to deprecated services. Applications need to be “instrumented” to report trace data to Zipkin. -

Fresco
An Android library for managing images and the memory they use
Fresco’s image pipeline will load images from the network, local storage, or local resources. To save data and CPU, it has three levels of cache; two in memory and another in internal storage. Fresco’s Drawee shows a placeholder for you until the image has loaded and then automatically shows the image when it arrives. When the image goes off-screen, it automatically releases its memory. A decompressed image - an Android Bitmap - takes up a lot of memory. This leads to more frequent runs of the Java garbage collector. This slows apps down. The problem is especially bad without the improvements to the garbage collector made in Android 5.0. On Android 4.x and lower, Fresco puts images in a special region of Android memory. It also makes sure that images are automatically released from memory when they’re no longer shown on screen. This lets your application run faster - and suffer fewer crashes. -

uCrop
Image cropping library for Android
We develop lots of different Android apps at Yalantis, and our experience shows that almost every application we deal with needs image cropping functionality. Image cropping can be used for various purposes, from ordinary adjustment of user profile images to more complex features that involve aspect ratio cropping and flexible image transformations. Since we want to provide all our customers with the best set of tools for image editing functionality, we decided to create uCrop, an image cropping library for Android. You might be wondering why we couldn’t just use one of the existing solutions for image cropping for Android. After all, you can find lots of them on Github and on the Android Arsenal. But here is the thing, none of these solutions could satisfy our requirements. Let’s take a quick look at the most popular open-source image cropping libraries and explain why they don’t quite fit the bill. -

AmazonMSK AWS Identity Access Management
Use AWS Identity and (IAM) to connect to Amazon Managed Streaming
The Amazon MSK Library for AWS Identity and Access Management enables developers to use AWS Identity and Access Management (IAM) to connect to their Amazon Managed Streaming for Apache Kafka (Amazon MSK) clusters. It allows JVM-based Apache Kafka clients to use AWS IAM for authentication and authorization against Amazon MSK clusters that have AWS IAM enabled as an authentication mechanism. This library provides a new Simple Authentication and Security Layer (SASL) mechanism called AWS_MSK_IAM. This new SASL mechanism can be used by Kafka clients to authenticate against Amazon MSK clusters using AWS IAM. After you've downloaded the code from GitHub, you can build it using Gradle. An uber jar containing the library and all its relocated dependencies except the kafka client and slf4j-api can also be built. At runtime, the uber jar expects to find the kafka client library and the sl4j-api library on the classpath. -

Lottie
Render After Effects animations natively on Mobile, Web & React Native
Lottie is a wonderful library for Android, iOS, Web, and Windows that works by parsing Adobe After Effects animations that have been exported as json with Bodymovin, and then rendering these natively on mobile and on the web! Now you can have beautiful animations without engineers having to recreate everything by hand. Building animations by hand is time consuming, and other animation alternatives like Gifs and Png sequences don’t offer the same flexibility and varied features that Lottie offers. With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever. Take a look at the many beautiful animation possibilities available to you on http://airbnb.io/lottie/ -

Picasso
A powerful image downloading and caching library for Android
Images add much-needed context and visual flair to Android applications. Picasso allows for hassle-free image loading in your application—often in one line of code! Many common pitfalls of image loading on Android are handled automatically by Picasso: Handling ImageView recycling and download cancelation in an adapter. Complex image transformations with minimal memory use. Automatic memory and disk caching. Adapter re-use is automatically detected and the previous download canceled. Transform images to better fit into layouts and to reduce memory size. You can also specify custom transformations for more advanced effects. Picasso supports both download and error placeholders as optional features. Resources, assets, files, content providers are all supported as image sources. For development you can enable the display of a colored ribbon which indicates the image source.
