Logs are not removed even after using proguard

Question

This is my proguard-project.txt

# 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.

My idea is to remove all the Logs even if obfuscation or any other optimization doesn't work.

The .apk file size in the bin folder is 1.82mb where as the one i get after Expoting is 1.42mb. So, i thought proguard did its job. But when i installed the .apk file on the Emulator and tested, all the Logs are still there.

Am i doing something wrong?

PS: The application crashes saying :

java.lang.RuntimeException: java.lang.NoSuchMethodException: a(Activity,int)

Hence i added these two lines in the proguard-project.txt:

• -keep public class com.myApp.mobileApp.**
• -keep public class com.myApp.mobileApp.** { *; }

Now it works, but the Logs are still showing up in the Logcat.

Thank You

Answer 1

you used: -dontoptimize

So proguard will NOT optimize the code, so log.x will NOT be removed(optimized)

Answer 2

You only keep the SherlockActivity class, not its inner classes.

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