# 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](../../docs/debugging.md#debug-mode)
|
||
|
|
* [Stacktrace recovery](../../docs/debugging.md#stacktrace-recovery)
|
||
|
|
* The internal assertions in the library are also permanently removed.
|
||
|
|
|
||
|
|
You can examine the corresponding rules in this
|
||
|
|
[`coroutines.pro`](resources/META-INF/com.android.tools/r8-from-1.6.0/coroutines.pro) file.
