App not appearing in app drawer

[Killy]

Hi
I’m fairly new to design so I need a little help. I’ve just created my app, and it installs but after installing I can’t find it in my app drawer. When I look for it in my apps list in settings, I find it but can’t open it, I only see uninstall and for stop is inaccessible.
What can I do to fix this?

In your app manifest make sure that the first or main activity (MainActivity) of your app is shown on your launcher by adding an intent filter with the action Main and a category as a launcher activity.
so it should look like this.

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