Android how to remove logging?

Question

Android

Log.* - does not make sense in the release version, only slightly loads the system. To get rid of the logs, I saw this check: if (BuildConfig.DEBUG) {} . Maybe my question is stupid, but is there a way to automatically remove the call to all logs in the project? (After all, doing the check also takes some time, even nanoseconds)

Answer 1

Use proguard/r8.
In the proguard-rules.pro file write the following:

-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String, int);
    public static int println(...);
    public static int v(...);
    public static int i(...);
    public static int w(...);
    public static int d(...);
    public static int e(...);
    public static int wtf(...);
}

Details here in the section Removing logging code

Answer 2

if (BuildConfig.DEBUG) {} the compiler will remove this code itself, there will be no check
