Zoom to an array of geometries

jonataspovoas

I I've been creating an app for android using the Arcgis Runtime SDK for Android 100.0. In it, I have an activity that receives an array of points, and I need to zoom the map so this all geometries in the array are shown at the it.

I know that there's a method setExtent(geometry) that zoom to any geometry, but I need to set my Extent to an array of them.
