Migrating to Capturix GPS SDK: Best Practices and TroubleshootingMigrating to a new GPS SDK can be a high-impact project: it affects app stability, battery consumption, privacy, and user experience. This guide covers practical planning, step-by-step migration tasks, performance and privacy considerations, and troubleshooting techniques specific to migrating to the Capturix GPS SDK. It’s written for mobile engineers, product managers, and dev leads tasked with planning and executing the transition.
Why migrate to Capturix GPS SDK?
- Better accuracy and smoothing algorithms — improved location filtering and multi-sensor fusion.
- Lower battery impact — power-optimized positioning and adaptive sampling.
- Enterprise features — geofencing, activity recognition, and configurable location policies.
- Cross-platform support — consistent APIs for Android and iOS.
- Advanced diagnostics — built-in logging, telemetry, and debugging tools.
Pre-migration planning
-
Stakeholder alignment
- Identify engineering owners, product owners, QA, security, and analytics teams.
- Define success criteria: accuracy targets, battery budgets, crash-free percentage, and rollout milestones.
-
Inventory current usage
- Catalog where the current GPS SDK is used: foreground tracking, background tracking, geofences, location-based notifications, maps, analytics, and third-party integrations.
- Note required OS versions and any native libraries currently in use.
-
Assess permissions and privacy flows
- List current permission prompts and rationale texts (Android fine/coarse location; iOS WhenInUse/Always).
- Confirm compliance needs (GDPR, CCPA, internal privacy rules).
-
Prepare a rollback strategy
- Keep the old SDK in a branch or feature toggle.
- Plan staged rollouts and instrumentation to measure regressions quickly.
-
Create a test matrix
- Devices (low-end to flagship), OS versions, battery states, network conditions.
- Scenarios: stationary, walking, driving, intermittent GPS, indoor/outdoor transitions.
Integration checklist — Android
-
Add SDK dependency
- Choose the Capturix AAR/maven coordinate and add to Gradle.
- Verify minSdkVersion and any required manifest entries.
-
Update AndroidManifest
- Add required services/receivers and metadata entries.
- Include required permissions:
- ACCESS_FINE_LOCATION
- ACCESS_COARSE_LOCATION (if used)
- ACCESS_BACKGROUND_LOCATION (Android 10+ if background tracking)
- FOREGROUND_SERVICE (if using foreground service)
- Add privacy-related metadata used by Capturix (if specified).
-
Initialize the SDK
- Initialize in Application.onCreate with API key/config object.
- Use environment flags (dev/test/prod) and enable diagnostic logging in non-prod only.
-
Implement permission flows
- Use runtime permission prompts for location. Follow platform best practices: explain Why before request, and only request background permission after the user accepts foreground permission.
- Detect OS-specific behaviors (Android 11+ approximate location toggle) and handle gracefully.
-
Configure location strategies
- Choose appropriate mode: high-accuracy continuous, balanced, or opportunistic/power-saving.
- Set sampling intervals, distance thresholds, and motion detection settings to match your app’s UX and battery targets.
-
Foreground service for background tracking
- Implement a foreground service when you need persistent background tracking; provide a clear notification and user controls to stop tracking.
-
Telemetry and logging
- Enable SDK diagnostics for test builds; forward SDK logs to your internal logging pipeline.
- Ensure logs don’t contain PII and follow privacy rules.
Integration checklist — iOS
-
Add SDK
- Install via CocoaPods, SPM, or manual framework integration. Ensure bitcode and architectures are correct.
-
Info.plist updates
- NSLocationWhenInUseUsageDescription and/or NSLocationAlwaysAndWhenInUseUsageDescription.
- Include any Capturix-specific keys or configuration.
-
Initialize the SDK
- Initialize at app launch with your API key and environment.
- Configure delegate callbacks for location updates, errors, geofence events.
-
Permission flows
- Request WhenInUse first; request Always only when a user-visible need exists and after WhenInUse granted.
- Handle App Tracking Transparency or other privacy prompts separately as needed.
-
Background modes
- Enable “Location updates” background mode only if necessary. Provide a clear explanation in App Store review notes for Always permission.
-
Power & accuracy tuning
- Choose desiredAccuracy and activityType appropriately (e.g., .fitness for pedestrian, .automotiveNavigation for driving).
- Use pausesLocationUpdatesAutomatically where appropriate.
-
Crash and telemetry handling
- Enable SDK diagnostics in test builds; integrate with your crash reporting while filtering sensitive data.
Feature parity and API mapping
- Map all current SDK calls to Capturix equivalents: start/stop tracking, request single location, geofence creation, geofence callbacks, activity detection, map utilities, and diagnostic APIs.
- Identify any missing feature and plan workarounds or feature requests.
- Example mapping table (replace with your app’s actual APIs):
Existing feature | Current SDK call | Capturix SDK call |
---|---|---|
Start background tracking | startTracking() | Capturix.startBackgroundTracking(config) |
Single location request | getCurrentLocation() | Capturix.requestCurrentLocation(completion) |
Create geofence | addGeofence(id, lat, lon, r) | Capturix.geofencing.add(id, region) |
Testing strategy
-
Unit & integration tests
- Abstract location provider behind an interface to allow dependency injection and mocking.
- Write tests for permission flows, SDK initialization, and error handling.
-
Instrumented device tests
- Run manual and automated tests across devices and OS versions.
- Use mock location and assisted GNSS tools where supported to simulate scenarios.
-
Field tests
- Real-world drives, walks, and indoor/outdoor transitions.
- Battery profiling during extended sessions (2–24 hours) for background tracking.
-
A/B and staged rollouts
- Canary release to small subset, monitor metrics (crashes, battery, accuracy).
- Expand gradually while monitoring.
-
Monitoring and KPIs
- Track location accuracy distribution, fix rate, battery drain, crash rate, and permission acceptance rate.
- Instrument key events from Capturix (SDK-start, SDK-stop, significant errors, GNSS state changes).
Performance & battery optimization tips
- Use activity detection to reduce sampling when the user is stationary.
- Prefer significant-change or passive providers for low-priority background tasks.
- Batch location uploads and avoid high-frequency network calls.
- Adjust GPS hot-start strategies; keep a cached last-known location for quick responses.
- Test with Doze and app standby states on Android; account for iOS suspend behavior.
Privacy & compliance best practices
- Only request the minimal level of location permission necessary.
- Provide clear in-app explanations for why location is needed and how it benefits the user.
- Minimize retention of raw location data; aggregate or downsample where possible.
- Encrypt location data in transit and at rest according to your security policy.
- Add a clear opt-out path and controls in settings.
Common migration issues and troubleshooting
1. SDK won’t initialize or API key rejected
- Verify API key and environment (dev/prod) values.
- Check for required manifest/Info.plist metadata.
- Inspect initialization errors in SDK logs and ensure network connectivity to Capturix endpoints.
2. No location updates (foreground)
- Ensure runtime permissions are granted.
- Verify platform settings: Android location services enabled; iOS location authorization status.
- Confirm desiredAccuracy/mode is not overly restrictive.
- Test with high-accuracy mode and known-good GPS conditions.
3. No background updates
- Android: confirm ACCESS_BACKGROUND_LOCATION and foreground service are implemented and notification visible.
- iOS: ensure Always permission or “location” background mode is enabled and App Store justification provided.
- Check battery optimizations / manufacturer-specific process kill rules (OEM settings on Android).
4. Poor accuracy or noisy traces
- Tune smoothing and filtering parameters in Capturix config.
- Use sensor fusion or fused location if available.
- Increase GPS time-to-first-fix allowances and enable A-GNSS assistance if supported.
5. High battery drain after migration
- Compare sampling rates and location priorities between old SDK and Capturix.
- Use lower-frequency modes for background tasks; enable batching.
- Profile wake locks and background services; ensure the foreground notification is being used correctly.
6. Geofence events unreliable
- Check geofence radius and device manufacturer optimizations.
- Verify geofence registration persistence across restarts and reboots.
- Use larger radii or server-side verification where appropriate.
7. Crashes or native errors
- Collect native crash logs and map them to Capturix SDK versions.
- Verify that native libraries and architectures match supported targets.
- Try disabling advanced features to isolate the cause, then reintroduce them.
Troubleshooting workflow
- Reproduce reliably and collect logs
- Enable SDK debug logs in staging and capture full logs; include device model, OS, and SDK version.
- Isolate variables
- Test with a minimal app that only initializes Capturix and requests a location to determine whether app code or SDK interaction causes the issue.
- Check device & OS quirks
- Validate against OEM battery-saving modes, privacy toggles, and location permission UI differences.
- Reach out to Capturix support
- Provide logs, reproduction steps, and device/OS details. Include timestamps and SDK version.
- Apply fixes and regressions tests
- Patch, run the test matrix, and stage rollout.

Appendix — Useful patterns & code snippets
Note: Replace these conceptual snippets with the exact Capturix SDK calls from the SDK documentation.
Android (pseudo-Kotlin)
class App : Application() { override fun onCreate() { super.onCreate() val cfg = CapturixConfig(apiKey = "YOUR_KEY", env = Env.PROD) Capturix.init(this, cfg) } } // Starting background tracking Capturix.startBackgroundTracking(TrackingConfig(mode = TrackingMode.BALANCED, intervalMs = 15000))
iOS (pseudo-Swift)
import CapturixSDK @main class AppDelegate: UIResponder, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { let cfg = CapturixConfig(apiKey: "YOUR_KEY", environment: .production) Capturix.initialize(config: cfg) return true } } // Request single location Capturix.requestCurrentLocation { result in switch result { case .success(let loc): print("Location: (loc.coordinate)") case .failure(let err): print("Error: (err)") } }
Final recommendations
- Start small: migrate a single flow (e.g., background tracking for one user cohort) before full replacement.
- Invest in telemetry and monitoring tailored to location performance and battery metrics.
- Keep a rollback path and staged rollout to reduce user impact.
- Work closely with Capturix support for SDK-specific tuning and undocumented platform nuances.
If you share specifics about your current SDK, target platforms, and primary use cases (real-time tracking, passive analytics, geofencing), I can produce a tailored migration checklist and configuration suggestions.
