android - Start activity by clicking on widget

Question

I newbie at programming Android and I try to do a widget which has be able get some data from ISP about my account. There are a lot of unknown things how to do it, but I have did a few things - I've got a widget with configure activity, where user should type login and password. Widget stores the data in SharedPerferences, and when it's time to update widget I use a Service to start an AsyncTask to getting it from ISP an account data. Now I want to do start an activity by click on widget. I've tried all advice which I found on this site and widget can't start activity. My widget based on another widget which placed here https://github.com/Arturus/MetrikaWidget. I dont understand what and where I should change to start activity by clicking on my widget. Thanks.

UPDATE: My update function, where I suggest I should place PendingIntent

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds)
{
    Log.d(TAG, "onUpdate");

    for (int appWidgetId : appWidgetIds)
    {
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }

    /* An updateAppWidget functions looks like as:

    Intent intent = new Intent(context, UpdateWidgetService.class);
    intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
    context.startService(intent);
    */

    Intent intent = new Intent(context, DetailedStatActivity.class);
    PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent, 0);

    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.layout);

    views.setOnClickPendingIntent(R.id.layout, pendingIntent);

    ComponentName componentName = new ComponentName(context.getPackageName(), WidgetProvider.class.getName());

    appWidgetManager.updateAppWidget(componentName, views);
}

Use this snippet in onUpdate() method of your widget AppWidgetProvider class:

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widgetlayout);
    Intent configIntent = new Intent(context, Activity.class);

    PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);

    remoteViews.setOnClickPendingIntent(R.id.widget, configPendingIntent);
    appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}     

Here widgetlayout is name of your widget layout and R.id.widget is it's parent layout id.

Edit:
Now,I see your code that you added to your question.You would to do:

PendingIntent.getActivity(context, 0, configIntent, 0);

(that start's activity) instead of

PendingIntent.getService(...);

that attempt to starts service.Good luck.
