What is the difference between -keep and -keepclassmembers in ProGuard?

Question

I read through http://proguard.sourceforge.net/index.html#manual/usage.html but cannot get their differences.

I tested with 2 different options and decompiled the outcome. Both seems to produce the same result.

-keep class * implements android.os.Parcelable {
    *;
}

-keepclassmembers class * implements android.os.Parcelable {
    *;
}

The first (-keep) will keep classes and class members that implement android.os.Parcelable from being removed or renamed.

The latter (-keepclassmembers) will keep class members only of classes that implement android.os.Parcelable from being removed or renamed.

Can you please clarify "from been removed or renamed"? – TWiStErRob Apr 25 '15 at 18:55

Shrinking and Obfuscating are among Proguard's Core functions. **Shrinking (Remove)** and **Obfuscating (Rename)**. – user1592811 Apr 28 '15 at 10:23
