To generate a heatmap for Mobile projects, you simple need to choose a date range. Smartlook will then create a gallery for all the fragments of the application within that date range.
NOTE: A gallery will contain all the heatmaps for every fragment in your application
You can also pause any recording and press Build heatmap button to generate a heatmap for this particular screen/fragment.
TIP: Take a look at our documentation regarding Recording navigation in regard to heatmaps.
