Obfuscation in Android Studio

by
  • Basic Obfuscation

To obfuscate code in Android studio just go to your build.gradle file in your Android Studio project:

enter image description here

Change the minifyEnabled property from false to true

This is a basic Obfuscation.

After generating the apk you can see the obfuscation result by decompiling the apk with any software. This page could help you:

In the obfuscation result you will see classes with name: a,b,c….

And the obfuscation variables and methods will have also names like aa,c,ac…

  • Normal obfuscation:

To obfuscate the code in a more complex form you could go to your root directory app and create a .pro file. For example in the following picture I have created the file: proguard-rules-new.pro. In the same directory you should see a file called proguard-rules.pro

Now add the file you have created to the build.gradle file

enter image description here

And edit the .pro file you have create with your own custom proguard rules
