This is my first project in Android Studio, and the code of my apps are not obfuscated.
Im using this configuration in build.gradle file:
I'm using the Build > Generate Signed APK... with the Run Proguard checked. And, when I have tested using the Apk_OneClick.v4.2, my code is completly easy to read:
Please, help-me. :(
Here is Some of Most Common Proguard Rules that you need to add in proguard-rules.pro file in Android Sutdio.
ButterKnife
-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }
-keepclasseswithmembernames class * {
@butterknife.* <fields>;
}
-keepclasseswithmembernames class * {
@butterknife.* <methods>;
}
Retrofit
-dontwarn retrofit.**
-keep class retrofit.** { *; }
-keepattributes Signature
-keepattributes Exceptions
OkHttp3
-keepattributes Signature
-keepattributes *Annotation*
-keep class okhttp3.** { *; }
-keep interface okhttp3.** { *; }
-dontwarn okhttp3.**
-keep class sun.misc.Unsafe { *; }
-dontwarn java.nio.file.*
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
Gson
-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.stream.** { *; }
Code obfuscation
-keepclassmembers class com.yourname.models** { <fields>; }
The other answers here are great references on using proguard. However, I haven't seen an issue discussed that I ran into that was a mind bender. After you generate a signed release .apk, it's put in the /release folder in your app but my app had an apk that wasn't in the /release folder. Hence, I spent hours decompiling the wrong apk wondering why my proguard changes were having no affect. Hope this helps someone!
Enable ProGuard
android {
buildTypes {
release {
minifyEnabled true
proguardFiles 'proguard-rules.pro'
}
}
}
