当我不使用 proguard/R8 时，为什么 com.google.android.play.core 中的 class 名称会被混淆/缩小？

Question

I have the following code in my app:

val reviewMan = ReviewManagerFactory.create(this)
Log.d(Plog.LOG_TAG, "created Google Play Review Manager: "+reviewMan.toString())

But the message that shows up in the console when I run it is:

created Google Play Review Manager: com.google.android.play.core.review.c@131b84b

This is an unobfuscated debug build (the build type's definition in build.gradle contains minifyEnabled false ) so why doesn't the message say, "created Google Play Review Manager: com.google.android.play.core.review.ReviewManager@131b84b"?

Answer 1

The reason for the class name c in the Google Play library is that the library itself has been minified before it is distributed through Maven.

The aar can be found here , and the classes.jar inside of it already has the minified names.
