Create a hidden AAR library in Android

Question

I created the aar library in Android studio. I see the code when I import it in another project. I don't want this. What should I do to prevent it from appearing? Do I need to edit it during compilation or in the code?

Follow the steps mentioned below

1. Copy library.pro file to your library project from this location:

   ...\android-sdk\tools\proguard\examples

2. Comment these lines when building from Android Studio, it should be probably kept/updated when building from the command line:

   -injars  in.jar
   -outjars out.jar
   -libraryjars  /lib/rt.jar

3. Update your library project build.gradle file to use library.pro:

   release {
     minifyEnabled true
     proguardFiles getDefaultProguardFile('proguard-android.txt'), 'library.pro'
   }

4. Sync and build the project and it should generate an obfuscated AAR file now.
