Enable log with obfuscation in Android using proguard

Question

I'm using proguard tool for obfuscation in Android. After making the release (export as signed APK), I can not see the Logs in LogCat. is there any specific flags than control this.

Thanks.

Edit 3: I use separate class for managing Logs, called LogUtil

Edit 2: Android Version android:minSdkVersion="14" android:targetSdkVersion="17"

Edit 1:

Proguard file :

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
-keepclassmembers class com.mvapps.booko.ui.activity.bookactivity.ReaderController.AndroidBridge {
  public *;
}


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

# Optimizations: If you don't want to optimize, use the
# proguard-android.txt configuration file instead of this one, which
# turns off the optimization flags.  Adding optimization introduces
# certain risks, since for example not all optimizations performed by
# ProGuard works on all versions of Dalvik.  The following flags turn
# off various optimizations known to have issues, but the list may not
# be complete or up to date. (The "arithmetic" optimization can be
# used if you are only targeting Android 2.0 or later.)  Make sure you
# test thoroughly if you go this route.


-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*,!code/allocation/variable
-optimizationpasses 5
-allowaccessmodification
-dontpreverify
-dontwarn
-ignorewarnings 


# The remainder of this file is identical to the non-optimized version
# of the Proguard configuration file (except that the other file has
# flags to turn off optimization).

Answer 1

The problem was in the separate class I use for logging, the developer of the class made this condition

if(DEBUG &&  BuildConfig.DEBUG)
{
    // log code here
}

Thanks for your efforts and sorry for that.

Answer 2

Please check your ProGuard configuration file for something to the effect of:

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

If this is present, please try removing it or adjusting it to suit.

Edit: If that doesn't work, please try removing all the optimisations starting from -optimizations...

-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*,!code/allocation/variable
-optimizationpasses 5
-allowaccessmodification
-dontpreverify
-dontwarn
-ignorewarnings

When I'm debugging my ProGuard files I often remove several lines or keep a wide range of classes until what I want works, then restore the file as needed.
