Android Studio - Benutzerdefinierte Listview-Crashing

Question

So folgte vor kurzem dieses Anweisungen des Videos auf, wie benutzerdefinierte Listview zu machen: https://www.youtube.com/watch?v=D0or0X12FMM

Das Programm beim Start abstürzt, seine DOA und nichts Show, bevor es abstürzt.

It's not logging any errors to the console.

Hier ist mein Code für alle in Video gezeigten Teile + mainifest:

Ich habe das Gefühl, es ist ein Problem mit dem Manifest. Nur basierend auf anderen Posts. Danke im Voraus!

Gerade Goto:

Android Studio --> File --> Setting --> Build, execution, deploy --> Instant run.

und sofortigen Lauf deaktivieren.
