If you're working with a map containing an editable layer, you can add new features to the map by taking the following steps:
For an example of the editing workflow of the app, open any of the Collection Sample maps. They are publically available through the Map Hub's gallery panel when connected to ArcGIS Online and contain editable layers.
The Select a feature type page displays, showing the types of features available for collection for each of the editable layers in the map.
The Edit pivot displays, providing access to the attributes, location, and attachments of the new feature.
You are taken to the map to collect the location of the feature. The app bar and hint text are for editing, and tapping the map places points or vertices for the feature being edited.
Collecting a new point feature
You must provide a single point for the geometry.
Collecting a new polyline feature
You must provide a minimum of two points for the geometry.
Collecting a new polygon feature
You must provide a minimum of three points for the geometry.
You are returned to the Edit pivot's location panel. The address of your geometry is added. You can tap edit if you need to make changes to your geometry.
The Choose Picture pivot of the device displays.
You'll see your added image as an attachment. The icon in the upper right corner of the image indicates that the attachment is waiting to be uploaded.
You are returned to the map, and your new feature is added.
