"ArcGIS Runtime SDK for Android Development note"-off-line integration technology: Offline vector data synchronization

1. Preface

In the previous article, we realized the editing operation of offline elements, this article mainly introduces the synchronization function of the offline data in the last part of the online integration technology, through the data upload, server-side versioning management, to achieve the entire process of data production management.

2.3, the realization of offline geo-database synchronization basic ideas:

1. Get the. geodatabase File storage Path
2. Get featureserviceinfo Service parameter information according to Featureservice service
3. Synchronize offline geodatabases based on featureserviceinfo information
4. Feedback synchronization results in the UI thread
