Changed package name doesn't work properly

Question

After I have been developing for quite some time m android application, I decided to change the package name. What I did was:

1. renamed the package tag in manifest

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   package="la.lala.lalala">
   

2. refactored the packages in the project treeview in AS

3. An successfully built the project. Now when I am trying to run in on my device I get this error

   Starting: Intent { act=android.intent.action.MAIN cat=
   [android.intent.category.LAUNCHER]
   cmp=**old.app.package_name**/**new.app.package_name**.controllers.ui.SplashActivity }
   Error type 3
   Error: Activity class    
   {**old.app.package_name**/**new.app.package_name**.controllers.ui.SplashActivity} does not exist.
   

In case you didn't understand the problem is that instead of running

new.app.package_name.controllers.ui.SplashActivity

it is trying to run

old.app.package_name/new.app.package_name.controllers.ui.SplashActivity

I cannot understand why since I did refactored it properly. I have also tried to restart and invalidate caches but this didn't work either.

Ok I fixed it after some googling and some tinkering with it. Thanks to this thread, I checked my build.gradle files. Found out that i was importing

apply plugin: 'android-library' 

which was deprecated, replaced it with

apply plugin: 'com.android.library'

and it worked correctly :)
