I'm wondering why my library always lost its documentation once it was built to AAR format. Also, Android Studio shrinks the code, i.e. the code before built always different with the code after built into AAR format, none originals. I want my library to has its own documentation and has the original code. You can see the different below:
Before built
After built into AAR format
Where is the documentation?! Also, you'll notice that the whole code are really shrunk and different.
So, how do I export AAR library with its documentation without shrink the code?
