VertiGIS Studio Mobile apps can be configured to support a Mobile Map Package (MMPK). An MMPK is an offline-capable package that contains basemaps and features. Unlike a Tile Package (TPK) which only contains map tiles, an MMPK is a full geodatabase that allows you to perform search and identify operations even while offline. However, if you want to edit data offline, you must use Map Areas.

Within the MMPK, each map is represented by a Mobile Map file (.mmap), which is nearly identical in structure to a web map. Mobile Designer allows you to configure layers and fields for a single .mmap file within an MMPK.

To configure a field from an MMPK, you must first add the field to ArcGIS popup configuration when creating the MMPK. You can set whether the field is searchable either in ArcGIS Pro or in Mobile Designer.

For more information about MMPKs, see Esri's Share a Mobile Map Package.

To use MMPKs, ensure the Auto-clean extensions setting is disabled in App Info.

If two applications download MMPKs with the same filename, the most recent download overwrites the existing file on the device. This can prevent the original app from accessing its data and may lead to synchronization issues or incorrect update notifications in the Local Data Manager.
The Local Data Manager detects conflicts based on the file name stored on the device, not the ArcGIS Portal item ID. Even if MMPKs have different item IDs in ArcGIS Online or Enterprise, identical file names will still result in an overwrite.

Use unique filenames for all MMPKs published to your portal. Avoid generic names such as OfflineData.mmpk or FieldMap.mmpk. Instead, include a project-specific identifier or version number (for example, WaterUtility_North_V1.mmpk) to prevent conflicts and ensure reliable data management.

Use an MMPK
