Obfuscation not working with proguard

Question

I am using various other libraries. But I have added their proguard configuration from their respository documentation I am not able to obfuscate my code and its inner variable using proguard. Even I am not able to obfuscate package names. I am still able to see logs on my android logcat. My app is running without any crash. I am confused whether minification was applied or not.

This is my app level gradle

   defaultConfig {
    resConfigs "en"
    applicationId "com.xxx.xxx"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 49
    multiDexEnabled true
    versionName "1.4.2-debug"
}
buildTypes {
    debug {
        minifyEnabled true
        debuggable true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    release {
        minifyEnabled true
        debuggable true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.config
    }
}
dexOptions {
    javaMaxHeapSize "4g"
}

And this is my proguard rules file.

Answer 1

I am not able to obfuscate my code and its inner variable using proguard :

your application seems not obfuscate because your progaurd rules are too broad and they are preventing most of your code from getting minified and obfuscated. for example following line:

-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider

I am still able to see logs on my android logcat :

you must remove debuggable true from release buildType of your gradle to prevent see logs in logcat.

Answer 2

I was having the line

-dontobfuscate 

in my proguard file which was blocking the obfuscation
