Question

in my android app, I have a button that leads to an activity which in some cases, does not launch because of an if statement.

What happens, is I kill the activity with .finish(); on the onCreate, so nothing happens when the user taps the button.

But I would like to display an alert, a Toast, to the user on the current activity. Not sure if this is really clear, but here’s what should basically happen:

• User is on homepage
• User click button to go to next activity
• Nothing happens because the activity is killed with the .finish(); on the onCreate.
• Here, a toast notification should be displayed on the homepage after the user clicked the button

Here’s my code so far :

try {
        this.storeMarkerList = new StoreMarkerList(this.mapView);
        StoreList list = (StoreList)getBaseApplication().getSessionParameter("selected.storelist", null);
        if (list == null || list.size() == 0){
            Toast.makeText(???, "No stores", 5000);
            this.finish();  
        }
        else {

(…)

Try this:

Toast.makeText(getApplicationContext(), "No stores", 5000).show();
