Open Spotify using Activity Starter

[Ab]

So, I saw a thread about a question for spotify activity but it didn't get fully replied because someone just put a tutorial to the app inventor 2 instead. 

So, I had an app and I wanted to trigger spotify through the app. So I did it via the activity starter. 

When the screen initialized or the button was pressed:

set ActivityStarter1.Action to "android.intent.action.VIEW"

set ActivityStarter1.ActivityPackage to "com.spotify.music"

set ActivitiyStarter1.ActivityClass to "com.spotify.music.MainActivity"

call ActivityStarter1.StartActivity
