It seems to be such a common refrain in science news: “Einstein proved right again”. At once comforting yet disappointing, a violation of Einstein’s theory would mean the potential for new physics and a new understanding of our reality. Einstein always seems to be right.
Companies, too, are born of challenges — often personal ones. The same goes for inventions, art projects, and social movements. In every area of life, there’s a connection between challenges and creativity.
Picasso 3 is the clear winner here as it’s only 36.2kb after R8 processes it. Coil is only 94.6kb which is significantly smaller than Glide (222.2kb) and Fresco without native code (244.1kb).
Whatever content I consumed, be it books, research papers, podcasts, videos, or articles, I was always mindful about them. I didn’t just skim through for the sake of completing them but paid attention to the content and tried to imbibe the values. The critical point here isn’t to try and remember every single thing you read. The point is to take note of the ones that stand out and make conscious efforts to include them in your life.Image loading libraries make it simple to fetch, decode, and display images. On Android, it’s very likely you’ll need to use one as the Android SDK mostly only exposes low-level APIs like BitmapFactory and ImageDecoder to load images. These APIs accept an InputStream or a Uri however threading, memory and disk caching, request management, memory management, opening/closing any resources, and other low-level concerns are left up to the developer to handle. The lack of high-level, simple APIs to load images makes it especially tough to load images from the network, which is a large reason why developers use open source image loading libraries.As we approach Election Day, Elemental is bringing you a progressive body scan for stress relief (also known as progressive muscle relaxation therapy; read more about the science behind it here).

Picasso (2 or 3) clearly came out ahead in the benchmark. It’s the smallest library and it also ran the image decode benchmarks the fastest. However, this benchmark doesn’t capture everything you should consider when choosing an image loading library. For instance, this benchmark doesn’t track memory allocation. Unlike the other libraries, Picasso doesn’t resize images exactly when it decodes them into memory; this will allocate larger than necessary bitmaps. Also, Picasso is missing some features that the other libraries support such as animated GIF support, direct memory cache access, custom transitions, and bitmap pooling.Each of the 4 main image loading libraries on Android (Coil, Fresco, Glide, and Picasso) has different design considerations and features. However, what if we wanted to compare their image decoding speed? The first thing to note is all the image loading libraries use the same low-level APIs to fetch and decode images. Every library uses BitmapFactory to decode image data. Likewise, every library uses OkHttp or HttpUrlConnection (though you should really use OkHttp) for its networking. Furthermore, each library uses the same Android SDK APIs to read image data from a Uri or File. The takeaway is that any performance differences between these libraries is largely due to the amount of overhead a library introduces by wrapping those API calls in a nice, high-level API.Again, I’m biased, but I believe Coil offers the best balance of performance, size, and features while being the only image loading library to integrate with Kotlin and Coroutines. Coil came second in the benchmarks and supports most of the features Glide supports as well as some it doesn’t (direct memory cache access, interceptors, event listeners). Also, Coil is designed with Jetpack Compose in mind and will have first party support for it once it is API-stable.
As expected, the control variant out performs all the image loading libraries. Picasso 2 and 3 both perform very well — especially for the file benchmark. Glide and Coil perform similarly on the network benchmark, however Coil is slightly faster at loading an image from a file. Fresco is the slowest, though it’s possible it’s not optimized for this benchmark. Typically, you don’t access the bitmap directly with Fresco and instead render an image directly with a SimpleDraweeView. This benchmark misses any optimizations inside of SimpleDraweeView.Express.js is now the standard in the Node.js world.

With superb cameras, a lighting fast chip that outclasses the competition, and a display that should be the most durable in a smartphone yet, the iPhone 12 Pro and 12 Pro Max should be the phones of phones. However, it isn’t.
Late last month I started getting emails from students in my media psychology classes. Had I seen The Social Dilemma, the new Netflix documentary on social media? And if so, what did I think?
Lastly, I wanted to compare the code size of each library inside the benchmarking APKs — not including transitive dependencies. This was measured using Android Studio’s APK analyzer. Note that “Fresco (Native)” includes at minimum 168.5kb of native code, which was added to its size.
These results were measured on a Pixel 1 running Android 10. The benchmarks use the AndroidX benchmarking library which runs the device in sustained performance mode, calls a function many times, and prints the median execution duration. The benchmarking code is available here and the raw results are available here. To reduce confounding variables, all libraries are using OkHttp for their networking. Also, I included a control variant in the benchmarks that manually opens an InputStream from the network/file Uri and decodes it directly using BitmapFactory.decodeStream. This variant should always perform best as it has no overhead. The versions of the libraries benchmarked are Coil (1.0.0), Glide (4.10.0), Fresco (2.3.0), Picasso 2 (2.8), and Picasso 3 (2832bcd). Lastly, it’s important to note that I wrote most of Coil and am not impartial.
Now, let’s take a look at the benchmarks after each library is run through Google’s R8 code optimizer. As release builds are typically built with R8 enabled, this should offer a better view of the library’s performance in production.
