 To enable **Mock Locations**, *Developer Mode* in Android must be enabled. It is best to google the [most recent procedure for this](https://www.google.com/search?q=how+to+allow+mock+location+on+android) but the following procedure should work:
 
 1) Open Android settings ![alt text](<img/MockLocation/SparkFun RTK Mock Location - Settings.png>)

 2) Open *About phone*

 3) Scroll to the bottom and click on *Build number* five or more times. The device will prompt as more taps are required.
 
 Once Developer Mode is enabled:

 2) Open *System*

 4) Scroll all the way to the bottom of a very long list of developer options. 
 5) Select the app to use for Mock Location. This is usually Lefebure or GNSS Master but can be tailored as needed.

 While we recommend [SW Maps for Android](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/gis_software_android/#sw-maps), there are a variety of 3rd party apps available for GIS and surveying for [Android](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/gis_software_android/), [iOS](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/gis_software_ios/), and [Windows](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/gis_software_windows/). We will cover a few examples below that should give you an idea of how to get the incoming NMEA data into the software of your choice.
 
+## AcrGIS Field Maps

+[ArcGIS Field Maps](https://play.google.com/store/apps/details?id=com.esri.fieldmaps&hl=en_US) by Esri is a popular GIS app. Unfortunately it does not have a built in NTRIP Client to allow high precision corrections down to the RTK device. To enable high-precision, a [mock location](connecting_bluetooth.md/#enable-mock-location) and an intermediary app such as [GNSS Master](gis_software_android.md/#gnss-master) or [Lefebure](gis_software_android.md/#lefebure) is needed.
+
+Once a [mock location](connecting_bluetooth.md/#enable-mock-location) provider is setup, open Field Maps.

+Field Maps will use the device's internal location as its default location provider. With GNSS Master or Lefebure providing the connection and corrections to the RTK device, and a mock location to the phone, Field Maps will have a super precise GNSS location and data collection can begin.
