ajouter ici plus de code, cela ne suffit pas. – Sajmon
Essayez de définir Intent.ACTION_VIEW au lieu de null –
Dans 'doInBackground()' lUriStr est créé comme NULL et n'est jamais assigné par une valeur correcte, votre doInBackground() renvoie NULL dans tous les cas, onPoseExecute() est toujours exécuté avec un paramètre NULL pResult et donc déclencher 'throw new RuntimeException (" Url NULL invalide. ");' vous avez défini. – yorkw
