App installed through android studio not shown in Launcher

Question

All of a sudden the app i'm working on doesn't show in the launcher. I can see it in Settings>Apps and it runs like a normal app when I start it from Android Studio.

So it sounds like I'm missing:

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

in the manifest. Nope they're there. What else can cause this? Does build gradle mess with this possibly?

This is my full manifest and build gradle file. Can anyone see something I'm missing?

You can actually have an intent filter with data android:host in the launcher activity. It just needs to be a separate filter to the one containing the launcher category. The following setup makes my activity both a launcher one and browsable in order to read input parameters:

<activity android:name=".MainActivity" android:label="@string/app_name_full">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="http"
                  android:host="www.giorgos.nl"
                  android:pathPrefix="/cv" />
            <data android:scheme="cv"
                  android:host="giorgos"/>
        </intent-filter>
</activity>
