  • Cancel asynchronous request
  • Debug logging / convert to cUrl call
  • Deserialization into POJO / POKO
  • Requests as coroutines
  • API Routing

24) coil

  • Fast: Coil performs a number of optimizations including memory and disk caching, downsampling the image in memory, re-using bitmaps, automatically pausing/cancelling requests, and more.
  • Lightweight: Coil adds ~2000 methods to your APK (for apps that already use OkHttp and Coroutines), which is comparable to Picasso and significantly less than Glide and Fresco.
  • Easy to use: Coil’s API leverages Kotlin’s language features for simplicity and minimal boilerplate.
