Image in Widget

I am trying to set image in image view in widget layout in onUpdate, but image is not updating

 @Override
     public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) 
     {
         Log.i(TAG, "onUpdate called");
         for (int appWidgetId : appWidgetIds) 
         {
             Bitmap bitmap=ImageUtils.getBitmap(context, appWidgetId);
             RemoteViews remoteView = new RemoteViews(context.getPackageName(), R.layout.widget);

             remoteView.setImageViewBitmap(R.id.imgView,bitmap);
             appWidgetManager.updateAppWidget(appWidgetId, remoteView);
         }
     }

xml layout for widget

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imgView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/ic_launcher" />

</LinearLayout>

Manifest file

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.demo.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
         <activity
             android:name=".WidgetConfig"
             android:label="@string/app_name" >
             <intent-filter>
                  <action
                    android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
