Introduction
Modern mobile apps often rely on access to sensitive device features—location, camera, microphone, contacts, and more. While these permissions are essential for delivering core functionality, managing them incorrectly can lead to app rejection, security vulnerabilities, or user mistrust.
If your app asks for too many permissions too soon—or fails to explain why—it risks being uninstalled. That’s why permission handling should be deliberate, transparent, and user-centric.

In this guide, you’ll learn how to handle permissions effectively in mobile apps, whether you’re building for Android, iOS, or using frameworks like React Native or Flutter. We’ll cover best practices, platform-specific guidelines, and how to design a better permission request experience.
Why Permission Management Matters
- User trust: Clear permission requests increase opt-in rates.
- App store compliance: Apple and Google have strict policies around sensitive permissions.
- Security and privacy: Apps should follow the principle of least privilege—only request what’s necessary.
- Functionality: Improper handling can break features or cause crashes.
Common Mobile App Permissions
Permission Type | Use Cases |
---|---|
Location | Navigation, local services, geotagging |
Camera | Photo capture, AR, scanning |
Microphone | Audio recording, voice input |
Contacts | Friend finder, communication apps |
Storage / Files | Downloading files, saving media |
Notifications | Alerts, engagement, reminders |
Bluetooth / Sensors | IoT devices, wearables, fitness apps |
Step 1: Request Only What You Need
Ask for permissions only when the user takes an action that requires them. Avoid requesting multiple permissions at app launch.
Example:
- Don’t ask for camera access until the user taps “Take Photo.”
- Request location only when accessing a map or nearby feature.
Step 2: Explain the “Why” Clearly
Use just-in-time permission prompts with clear, user-focused messaging.

Android:
Use a dialog before triggering the system permission request:
kotlinCopyEditAlertDialog.Builder(this)
.setTitle("Location Access Needed")
.setMessage("This feature helps you find nearby services.")
.setPositiveButton("Allow") { _, _ -> requestLocationPermission() }
.setNegativeButton("No Thanks", null)
.show()
iOS:
Add a purpose string in your app’s Info.plist
:
xmlCopyEdit<key>NSCameraUsageDescription</key>
<string>We need access to your camera so you can take profile photos.</string>
Failing to include these strings results in App Store rejection.
Step 3: Use Platform-Specific APIs Correctly
Android (Runtime Permissions)
Since Android 6.0 (API level 23), permissions are granted at runtime.
kotlinCopyEditActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.CAMERA), CAMERA_REQUEST_CODE)
Check permission before requesting:
kotlinCopyEditif (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
// Proceed
}
Handle results in:
kotlinCopyEditoverride fun onRequestPermissionsResult(...) { /* handle response */ }
iOS (Authorization Status)
Use appropriate frameworks:
swiftCopyEditswitch AVCaptureDevice.authorizationStatus(for: .video) {
case .authorized:
// Access granted
case .notDetermined:
AVCaptureDevice.requestAccess(for: .video) { granted in
// Handle result
}
case .denied, .restricted:
// Show guidance to change settings
}
Step 4: Gracefully Handle Denied or Revoked Permissions
Don’t assume the user granted access. Always check status and provide fallback UI or guidance.

Tips:
- If permission is denied, offer a clear message and instructions to update it in settings.
- Never crash or break critical flows if access is denied.
- Provide alternatives where possible (e.g., manual input instead of camera).
Step 5: Support Permission Revocation
Both Android and iOS allow users to change permissions at any time. Your app should adapt dynamically.
Android:
Check for permission every time a sensitive action is triggered.
iOS:
Listen to app state changes and re-check authorizations on resume.
Step 6: Respect App Store Guidelines
Both Apple and Google enforce strict rules on permission usage:
Apple (App Store Review Guidelines)
- Only request necessary permissions.
- Include a valid
NS*UsageDescription
for every sensitive permission. - Misuse can result in app rejection.
Google Play Policy
- You must declare and justify permissions in the Play Console.
- Sensitive permissions (e.g., SMS, Contacts) require a valid use case.
- Background location access requires additional review.
Step 7: Use Permission Handling Libraries
If you’re using frameworks like React Native or Flutter, libraries can simplify permission workflows.

React Native:
react-native-permissions
react-native-permission-handler
Flutter:
permission_handler
package
dartCopyEditPermission.camera.request();
These libraries handle platform differences and fallback handling.
Conclusion
Handling permissions in mobile apps isn’t just about functionality—it’s about building user trust and complying with evolving platform policies. By requesting permissions responsibly, explaining their use clearly, and designing fallbacks, you ensure a smoother user experience and fewer headaches during app reviews.
Remember: the best permission is the one users feel comfortable granting—because they understand its value.
