在我的应用程序中，我有很多行日志，例如 Log.i()、Log.e() 和 Log.d()。我通过我的应用程序广泛使用这些日志。

在我运行我的应用程序后，如果我将设备连接到 Eclipse，我可以看到数百行日志。我的问题是这种行为会降低应用程序速度吗？

更新

感谢弗兰克的建议。我将提议的代码添加到 proguard.cfg 中，然后导出新的 APK 文件。花了很多时间，但最终生成了新的 APK 文件。但是，当我在真实设备中对其进行测试时，我仍然可以看到日志。

这是我的 proguard.cfg：

# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
    native <methods>;
}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**

# Hesam - Remove all logs
-assumenosideeffects class android.util.Log {
    public static int v(...);
    public static int d(...);
    public static int i(...);
    public static int w(...);
    public static int e(...);
}

答案很明显，是的。

但是有一个解决方案，您可以要求 Proguard 删除您想要的任何级别的日志语句。像这样，您的用户不会受到他们无论如何都看不到的详细日志记录的影响。

将以下内容添加到您的 Proguard 配置中：

-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
    public static *** i(...);
    public static *** w(...);
    public static *** e(...);
    public static *** wtf(...);
    }

这将删除 LOG.d 和 LOG.v 语句，您可以随意扩展..
