Default Activity Not Found Error Android Studio

I am having trouble launching my app since it gives me the Default Activity not Found error. I have read other threads and have tried adding/changing the position of the following code:

<intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name = "android.intent.category.LAUNCHER" />
</intent-filter>

but it still does not work. I have also tried 

File -> Invalidate Caches / Restart...

and still does not work. Below is my Android Manifest.xml file. I would like to start my app with the activity named ".Main2Activity". Also note that for some reason my .xml files in Design mode appear with a black background and weirdly different. 

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

Have you tried this: https://stackoverflow.com/a/22028681/1101730.

Add these lines to the build.gradle file inside the android { ... } block:

android { ... sourceSets { main.java.srcDirs += 'src/main/' } }

After editing the file, click Tools > Android > Sync Project with Gradle Files.

Last thing I can think of is to click on Run > Edit configuration and make sure that your activity is selected to be the launching activity.

<activity>
        android:name=".MapsActivity"
        android:label="@string/title_activity_maps" />

check, You must have error in xml for that. It'll be :

<activity
        android:name=".MapsActivity"
        android:label="@string/title_activity_maps" />

isn't it?
