i have setup proguard library, I've tried to remove -keep but still not working. are there another setup to make obfuscate code ?

Your proguard rules are wrong I guess , you wrote `-keep public class * extends android.app.Activity` I think that means proguard won't touch any classes which extend Activity — Manohar, Apr 04 '18 at 07:33
I've tried to delete -keep public class * extends android.app.Activity but still not obfuscate, and when running my app error — M. Johnson, Apr 04 '18 at 07:45
you are `-keep`'ing a lot of classes. Probably you have decompiled classes, which you set to be kept. — Vladyslav Matviienko, Apr 04 '18 at 08:08

it seems you are not enable progurad enable it by add this to your app build.gradle

buildTypes {
        release {
            debuggable false
            minifyEnabled true
            shrinkResources true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
    }

I've tried like your answer, and decompile in http://www.javadecompilers.com/apk but still not working – M. Johnson Apr 04 '18 at 08:04
are you trying build apk in debug mode?please get release mode see this link https://stackoverflow.com/questions/19619753/how-to-build-a-release-apk-in-android-studio – Ahmad Nemati Apr 04 '18 at 08:07
can you remove all progurad-rules.pro content and test it again?maybe your rules effect it – Ahmad Nemati Apr 04 '18 at 08:14
i try remove proguard except library proguard but still not working, because if i remove library proguard, can't generate apk, have error – M. Johnson Apr 04 '18 at 08:19
thanks @ahmad, after i try again working, the problem proguard of library, i remove all `-keep` but `dontwarn lib` not removed, but have another problem, app crash when running after proguard library `removed` – M. Johnson Apr 05 '18 at 04:01
so now you find what is problem i suggest you to use this link https://github.com/yongjhih/android-proguards for add exactly proguard rules that you need – Ahmad Nemati Apr 05 '18 at 05:07
