Estoy tratando de averiguar cómo puedo implementar este código en mi código fuente existente. Actualmente tengo alguna fuente que muestra una vista de lista de todas las aplicaciones instaladas y al hacer clic, se enviará la intención a la aplicación. Necesito ayuda sobre cómo extraer el icono y agregarlo a la vista de lista.

Cualquier ayuda, edición de código fuente, enlaces, etc. me ayudaría a resolver esto.

Gracias
