[android-developers] Newbie: Widget onUpdate called only on creation

[Eduardo Yáñez Parareda]

Hello, I'm developing my first widget so I've following Google
tutorials, but I don't get it works as I expect, it only calls
onUpdate when the widget is installed, but it isn't called again...

<code>
public class TestWidgetProvider extends AppWidgetProvider {
    // Log tag
    private static final String TAG = "TestWidgetProvider";

    public void onUpdate(Context context, AppWidgetManager
appWidgetManager, int[] widgetIds) {
        Log.d(TAG, "onUpdate");
        final int N = widgetIds.length;

        // Por cada widget asociado al provider
        for (int i = 0; i < N; i++) {
            int widgetId = widgetIds[i];
            updateWidget(context, appWidgetManager, widgetId);
        }
    }

    static void updateWidget(Context context, AppWidgetManager
appWidgetManager, int widgetId) {
        // Obtenemos las vistas del widget
        RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.gpro_widget_layout);

        // Actualizamos el texto del widget
        long time = System.currentTimeMillis();
        String text = String.format("Hora: %d ms.", time);
        views.setTextViewText(R.id.text, text);

        // Actualizar el widget
        appWidgetManager.updateAppWidget(widgetId, views);
    }
}
</code>
