Edit and sync features

This sample demonstrates how to synchronize offline edits with a feature service.

How to use the sample

1. Pan and zoom into the desired area, making sure the area you want to take offline is within the current extent of the MapView.
2. Tap on the Generate Geodatabase button. This will call generateGeodatabase(), which will return a GenerateGeodatabaseJob.
3. Once the job completes successfully, a GeodatabaseFeatureTable and a FeatureLayer are created from the resulting Geodatabase. The FeatureLayer is then added to the ArcGISMap.
4. Once the FeatureLayer generated from the local Geodatabase is displayed, a Feature can be selected by tapping on it. The selected Feature can be moved to a new location by tapping anywhere on the map.
5. Once a successful edit has been made to the FeatureLayer, the Sync Geodatabase button is enabled. This button synchronizes local edits made to the local GeoDatabase with the remote feature service using syncGeodatabase() which generates SyncGeodatbaseParameters and passes them to a SyncGeodatabaseJob.
6. Once the job successfully completes, the local edits are synchronized with the feature service.

Provision your device

1. Download the data from ArcGIS Online.
2. Extract the contents of the downloaded zip file to disk.
3. Create an ArcGIS/samples/MapPackage folder on your device. You can use the Android Debug Bridge (adb) tool found in /platform-tools.
4. Open up a command prompt and execute the adb shell command to start a remote shell on your target device.
5. Navigate to your sdcard directory, e.g. cd /sdcard/.
6. Create the ArcGIS/samples/TileCache directory, mkdir ArcGIS/samples/TileCache.
7. You should now have the following directory on your target device, /sdcard/ArcGIS/samples/TileCache. We will copy the contents of the downloaded data into this directory. Note: Directory may be slightly different on your device.
8. Exit the shell with the, exit command.
9. While still in your command prompt, navigate to the folder where you extracted the contents of the data from step 1 and execute the following command:
   • adb push SanFrancisco.tpk /sdcard/ArcGIS/samples/TileCache
