Answer 1

You could use the following proguard-rule in order to ignore all Debug and Verbose Logs in a release:

# ignore all Debug and Verbose Logs in a release
-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
}

So you dont have to "disable" all your Logs manually - they get just obfuscated.

In order to apply this proguard rule you have to use the optimization function of proguard by modifying your gradle file:

buildTypes {
    release {
        shrinkResources false
        minifyEnabled true
        zipAlignEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),
                'proguard-rules.pro'
        signingConfig signingConfigs.config
        proguardFile '/<your-custom-file>/app/proguard-rules.pro'
        debuggable false
    }
}

Also have a look in the proguard manual: https://www.guardsquare.com/en/proguard/manual/usage

For my project I was able to get rid of the debug messages with the following.

1. First I went to the proguard-rules.pro file that should be near your build.gradle file. In that file I added:

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

2. Then I went to the build.gradle file and added:

   buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } }

you can do the hard way and use remplace " Ctr + shift + r " and remplace all the "log." by " // " to put in comment all the log request.
