Getting “Default activity not found” even though setting correct intent filters

I'm trying to change my default activity in Android Studio. I have added the MAIN and LAUNCHER intent tags to VrMainActivity, removed the MAIN and LAUNCHER tags from MainActivity and still get a "Default Activity not found" error. I have also invalidated cache/restarted. Also no errors in the Merged Manifest section of the editor, totally stuck on what the problem is.

Here's my manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.thanics.andrew.halocontrol">

<uses-permission android:name="android.permission.INTERNET" />

you need to use <category android:name="android.intent.category.LAUNCHER" /> to make any
activity as launcher .

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

Just replace <category android:name="com.google.intent.category.LAUNCHER" /> to <category android:name="android.intent.category.LAUNCHER" /> inside your Manifest.

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

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

try to add this line:

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


in the <intent-filter> tag

<intent-filter>
