如何配置我的 proguard-project.txt 文件以仅删除日志

Question

这是我现在在 proguard-project.txt 中使用的代码

# 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{*;}
-keep public class * extends android.app.Application{*;}
-keep public class * extends android.app.Activity{*;}
-keep public class * extends android.app.MapActivity{*;}
-keep public class * extends android.app.PreferenceActivity{*;}
-keep public class * extends android.view.View{*;}
-keep public class * extends android.widget.BaseAdapter{*;}
-keep public class * extends android.app.Service{*;}
-keep public class * extends android.content.BroadcastReceiver{*;}
-keep public class * implements android.view.View.OnTouchListener{*;}
-keep public class * implements android.view.View.OnClickListener{*;}
-keep public class * extends com.readystatesoftware.mapviewballoons.BalloonItemizedOverlay<OverlayItem>{*;}

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class com.actionbarsherlock.** { *; }
-keep interface com.actionbarsherlock.** { *; }

-libraryjars libs/android-support-v4.jar
-libraryjars libs/apache-mime4j-0.6.jar
-libraryjars libs/httpmime-4.0.1.jar
-libraryjars libs/libGoogleAnalyticsV2.jar

-assumenosideeffects class android.util.Log {*;}

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembers 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.**
-dontwarn org.apache.**

但是日志仍然出现在 logcat 中。

所以，我只想知道代码必须是什么，以便只删除日志。不需要其他优化。

谢谢

ProGuard 配置文件分为几个部分（从 Android SDK r20 开始），在 project.properties 中指定：

  proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

如果没有禁用优化，则只能删除日志记录，这需要不同的全局配置文件：

  proguard.config=${sdk.dir}/tools/proguard/proguard-android-optimize.txt:proguard-project.txt

文件 proguard-project.txt 只需要包含项目特定的配置。您的文件似乎包含太多内容，但这些是删除日志记录的设置：

-assumenosideeffects 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(...);
}

类似的问题和答案：

• Removing Log call using proguard
• Removing unused strings during ProGuard optimisation
• Removing logging with ProGuard doesn't remove the strings being logged

如果您在 Android Studio 上遇到此问题，则必须将 Eric 的解决方案应用于您的 build.grade 文件（在应用级别）。替换：

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

与：

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
