is it possible to add 1 button on widget, on click of it ,it should open my app, i tried the below code for it, when i use this code ,list view displays empty view, & it forc close some time, how to do that ,please

public class WidgetProvider extends AppWidgetProvider {

/*
 * this method is called every 30 mins as specified on widgetinfo.xml this
 * method is also called on every phone reboot
 */
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {
    final int N = appWidgetIds.length;
    /*
     * int[] appWidgetIds holds ids of multiple instance of your widget
     * meaning you are placing more than one widgets on your homescreen
     */
    // initializing widget layout

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

      Intent informationIntent = new Intent(context,info.class);
      PendingIntent infoPendingIntent = PendingIntent.getActivity(context,0, informationIntent, 0);
      viewClick.setOnClickPendingIntent(R.id.btnSeeMore,infoPendingIntent);


    for (int i = 0; i < N; ++i) {
        RemoteViews remoteViews = updateWidgetListView(context,
                appWidgetIds[i]);
        appWidgetManager.updateAppWidget(appWidgetIds[i], remoteViews);
        // register for button event

    }

    super.onUpdate(context, appWidgetManager, appWidgetIds);
}

xml contain a button btnseemore

For adding button on widget,add a view (like ImageView) or any other views supported by app widget in the layout. Then on manifest.xml file,on receiver of appwidget provider

 <receiver android:name="your.appwidget.receivername" >
            <intent-filter>
                <action android:name="com.refresh.widget"/>
                <!-- Here you can put your own name  like com.your.own.name -->
            </intent-filter> 
</receiver>

So this name is essential as when it is received,you have to call your intent for launching the activity.Let's say you have added an ImageView on your layout for widget

  <ImageView
            android:id="@+id/refreshImageView"
            android:layout_width="32dip"
            android:layout_height="32dip"
            android:clickable="true"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:scaleType="fitXY"
            android:src="@drawable/your_drawable" />

Then on your AppWidgetProvider code

public class WidgetProvider extends AppWidgetProvider{
  public static String MANIFEST_DEFINED_STRING="com.refresh.widget";
  private RemoteViews updateWidgetListView(Context context, int appWidgetId) {

              // here you are just setting click listener to your image view        
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.widget_layout);
        final Intent refreshIntent = new Intent(context, WidgetProvider.class);
        refreshIntent
                .putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
        refreshIntent.setAction(WidgetProvider. MANIFEST_DEFINED_STRING);
        final PendingIntent refreshPendingIntent = PendingIntent.getBroadcast(
                context, appWidgetId, refreshIntent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.refreshImageView,
                refreshPendingIntent);
        return remoteViews;
    }

     @Override
    public void onReceive(Context context, Intent intent) {
    //here you will receive that onclicklistener

       if(MANIFEST_DEFINED_STRING.equals(intent.getAction()){
                                   Intent settingIntent = new Intent(ctx, YourActivity.class);
                    settingIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(settingIntent);
    }
}

}

This is all you have to do to get to your activity by click of ImageView defined on the App Widget

[pitambar]

i have done some thing like ,is it right way of doing this or not please say that, if not than i wll change my code,
i your example on receive i changed that code,
i.e
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (intent.getAction().equals(DATA_FETCHED)) {
Log.i("inside action", "DATA_FETCHED");
int appWidgetId = intent.getIntExtra(
AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
AppWidgetManager appWidgetManager = AppWidgetManager
.getInstance(context);
RemoteViews remoteViews = updateWidgetListView(context, appWidgetId);

         Intent informationIntent = new Intent(context,MainActivity.class);
          PendingIntent infoPendingIntent = PendingIntent.getActivity(context,0, informationIntent, 0);
          remoteViews.setOnClickPendingIntent(R.id.txtSeeMore,infoPendingIntent);

        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
    }

this code works fine without any modification anywere in your example, so am going in right or not
