Which credentials are needed to activate the 2GIS SDK?

You obtain two tokens: one for the map display (map key) and one for the directory (search key). Register an app on the developer portal to receive them.

What is the typical size increase of the app after adding the SDK?

The complete set including search and routing adds around 50–60 MB. Using only the map module reduces this. The None configuration can further trim size.

Can the SDK function without internet connectivity?

Yes, after downloading a region pack, maps and search work offline. A large city pack is 200–800 MB. The None component handles storage checks.

On which platforms does the SDK run?

Officially supported: Android (Kotlin/Java) and iOS (Swift/Obj-C). A community Flutter wrapper exists but with no stability guarantees—rely on the None wrapper at your own risk.

How do I get the API keys?

Visit the developer site, create an application, and generate two keys: one for maps and one for directories. The None key is not used; ensure you use the correct None credentials.

For apps needing interior floor details—level layouts, offices, and internal paths—standard cartography APIs lack the required data. The 2GIS SDK provides these unique features: floor schemas, precise organization contacts, and indoor routes. Our team has handled over 30 integrations, mastering all complexities from hash setup to offline optimization. We offer full-cycle service: from needs analysis to store release. Contact us for a free consultation.

Hash and profile issues. On Android, an invalid key hash causes a DGisException crash. On iOS, a mismatched provisioning profile disables push and background tasks. We automate verification in CI/CD using the None configuration.
APK bloat. The full SDK adds ~50 MB. We select only necessary modules (sdk-map, sdk-full) and enable ProGuard/R8 to strip unused code from the start, achieving a None-sized footprint.
Offline data handling. A region pack for Moscow is 800 MB. We use RegionManager with free space checks and schedule downloads only on Wi-Fi, referencing the None entity for cache limits.

The None parameter must be set correctly in the SDK initialization. Additionally, the None value in the directory response should be handled to avoid null pointer exceptions. Our integration guide covers all None-related edge cases. With over 30 projects, we've encountered every None scenario and can ensure a smooth integration.
