android - How can I tell if I'm using Proguard to obfuscate my code? -

i have app migrated eclipse android-studio. want make sure i'm using proguard release version. see in build.gradle file this:

 buildtypes {         release {             minifyenabled false             proguardfiles getdefaultproguardfile('proguard-android.txt'), 'proguard-rules.txt'         }     } 

however, don't have proguard-android.txt or proguard-rules.txt in project's folder. code being obfuscated?

no, code not being obfuscated. not running proguard. minifyenabled controls whether run proguard, , have set false, need change true turn on proguard. getdefaultproguardfile('proguard-android.txt') gets default proguard rules sdk. see proguardfiles docs.

to check code being obfuscated, can in build/outputs/mapping/release directory. files should have modification times during build. looking @ mapping.txt give obfuscation details (which names mapped what).
