I have to protect my app by enabling Proguard obfuscation in Android Studio. I have searched for the process of how to apply it but i did not get any clear solution. When i try it, i always get an error. So can anyone tell me the clear steps to apply it in my app?
I am doing this by the following steps:
-keepclassmembers class com.dom925.xxxx
Error:Execution failed for task ':app:packageRelease'.
Unable to compute hash of D:\Android\Pojectname\app\build\intermediates\classes-proguard\release\classes.jar
I figured out the problem:
Open up the proguard-rules.pro for your project and add this to the bottom:
-dontwarn java.nio.file.Files -dontwarn java.nio.file.Path -dontwarn java.nio.file.OpenOption -dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
Basically how I solved it was this I tried to run my app in 'release' mode and got a bunch of errors similar to this guy here: https://github.com/square/okio/issues/144
I pretty much followed what he said and fixed it.
Hope this can help others with generating their APK's!
