How to config my proguard-project.txt file to remove just Logs

Question

This is the code i am using right now in the proguard-project.txt

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


        

Answer 1

The ProGuard configuration file is split into several parts (as of Android SDK r20), which are specified in project.properties:

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

You can only remove logging if optimization is not disabled, which requires a different global configuration file:

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

The file proguard-project.txt only needs to contain project-specific configuration. Your file seems to contain way too much, but these are the setttings to remove the logging:

-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(...);
}

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

If you're stuck with this on Android Studio, the solution of Eric must be applied to your build.grade file (at the app level). Replace:

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

with:

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