I've a need to remove all logging from my release App type. I've tried configure proguard to do it for me. My configuration mostly match the one provided in here: proguard doesn't remove logs .
I've changed proguard-android.txt
to proguard-android-optimize.txt
but with no luck. After going through Proguard manual and checking output of :
-whyareyoukeeping class android.util.Log {
public static boolean isLoggable(java.lang.String, int);
public static int v(...);
public static int i(...);
public static int w(...);
public static int d(...);
public static int e(...);
public static int wtf(...);
}
learned that this couldn't be removed because of:

android.util.Log
is a library class.
android.util.Log: boolean isLoggable(java.lang.String,int)
is a library method.

is a library method.

android.util.Log: int d(java.lang.String,java.lang.String)
is a library method.

android.util.Log: int wtf(java.lang.String,java.lang.String)
is a library method.

is a library method.
android.util.Log: int wtf(java.lang.String,java.lang.String,java.lang.Throwable)
is a library method.
What could be reason for that? Maybe some other Proguard option? Is there any other option to enforce logs removal?
With help of Guardsquare support I've been able to find out problem. One of libraries has -dontoptimize in its ProGuard config file. Helpful to narrow down this issue is option -printconfiguration [filename]
