Optimization

R8 and ProGuard rules are bundled into this module. R8 is a replacement for ProGuard in Android ecosystem, it is enabled by default since Android gradle plugin 3.4.0 (3.3.0-beta also had it enabled). For best results it is recommended to use a recent version of R8, which produces a smaller binary.

When optimizations are enabled with R8 version 1.6.0 or later the following debugging features are permanently turned off to reduce the size of the resulting binary:

Debugging mode
Stacktrace recovery
The internal assertions in the library are also permanently removed.

You can examine the corresponding rules in this coroutines.pro file.
