La file d'attente est vérifié toutes les 5 secondes et émet une activité de début de la fenêtre s'il y a un élément comme suit


SMSPopup.msg = main.msgs.get(0);

Y at-il une raison que vous utilisez un popupWindow et pas un toast ou un dialogue? – Falmarri

Toast ne suffirait pas. Quelle est la différence entre le dialogue/popup – RenegadeAndy

D'autres articles ont souligné le problème de la tentative de faire apparaître trop tôt. Cependant, je pense aussi que vous devriez vraiment pas faire cela:

public static String msg;

SMSPopup.msg = main.msgs.get(0);

Ce n'est pas la bonne façon de transmettre des données à un autre Activity. Vous devez régler les données en tant que Extra sur le Intent, comme ceci:

Intent testActivityIntent = new Intent(context.getApplicationContext(), com.andy.tabletsms.work.SMSPopup.class); 
testActivityIntent.putExtra("com.andy.tabletsms.message", main.msgs.get(0)); 
testActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
context.startActivity(testActivityIntent);

Vous pouvez alors récupérer le message dans votre cible Activity:

private String msg; 
... 
Intent intent = getIntent(); 
if (intent != null){ 
    Bundle bundle = intent.getExtras(); 
    if (bundle != null){ 
     msg = bundle.getString("com.andy.tabletsms.message"); 
    } 
}

Vous affichez votre pop-up trop tôt, il ne peut être affiché après est montré la fenêtre de l'activité. Vous pouvez simplement poster un Runnable pour afficher le popup.

Oh right !!!! SO au lieu de commencer une nouvelle activité - il suffit d'utiliser le contexte du gestionnaire d'alarme et afficher à l'aide d'un runnable? Des exemples exécutables ?! – RenegadeAndy

Pouvez-vous montrer un exemple de ceci? – RenegadeAndy

Il semble que vous ne pouvez pas afficher un alertdialog etc d'un récepteur de diffusion - il doit commencer une nouvelle activité .... – RenegadeAndy
