sometimes AS would destroy that folder for no damn reason.
instead of rebuilding your project, rebuild just the manifests folder and xml file :

tool bar : file Right Click -> New -> Other > Android Manifest

in the new manifest .xml copy paste the contents from some other manifest file and fudge around with the package name field and the main activity field,


<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android=""









        <activity android:name="com.yotamarker.lgkotlin1.MainActivity">


                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />





package="com.yotamarker.lgkotlin1">  :cop3:  :guro:

<activity android:name="com.yotamarker.lgkotlin1.MainActivity">
