A Restaurant In Your Own Home

Step #6: Show a Random Restaurant

Finally, we need to add some smarts that will actually display a random

restaurant in the app widget. To do this, we will override the onUpdate()

method in our AppWidget class and have it do the database I/O to find a

random restaurant.

With that in mind, add the following onUpdate() implementation to

AppWidget:

@Override

public void onUpdate(Context ctxt,

AppWidgetManager mgr,

int[] appWidgetIds) {

ComponentName me=new ComponentName(ctxt, AppWidget.class);

RemoteViews updateViews=new RemoteViews("apt.tutorial",

R.layout.widget);

RestaurantHelper helper=new RestaurantHelper(ctxt);

try {

Cursor c=helper
