Permission request flow in Android Kotlin - Build, Publish & Deploy

Build & Publish - Permission request flow

Performance Impact

Requesting permissions itself has minimal impact on frame rate or memory. However, improper handling can cause UI freezes if requests block the main thread. Frequent or repeated permission dialogs annoy users and may cause app abandonment, indirectly affecting perceived performance.

Battery usage is unaffected by permission requests, but granted permissions may enable features that consume more battery (e.g., location updates).

Optimization Tips

• Request permissions only when needed, not at app start, to avoid blocking UI.
• Use asynchronous callbacks to handle user responses without freezing the UI thread.
• Explain clearly why permissions are needed before requesting, reducing repeated denials.
• Cache granted permissions state to avoid unnecessary requests.
• Test on various Android versions to handle permission model differences smoothly.

App Size and Startup Time Impact

Permission request flow code adds negligible size to the app bundle. It mainly involves system dialogs and callbacks managed by Android OS.

Requesting permissions at startup can delay app readiness and increase perceived startup time. Request permissions contextually to keep startup fast.

iOS vs Android Differences

Android uses runtime permission requests starting from Android 6.0 (API 23). Permissions are requested individually or in groups, and users can deny or grant them anytime.

iOS also requires runtime permission requests but uses different APIs and permission types. iOS permissions are requested via system dialogs triggered by specific APIs (e.g., location, camera).

Android requires explicit permission checks and requests in code, while iOS permissions are often requested implicitly when accessing protected resources.

Store Review Guidelines

• Google Play: Must declare all requested permissions in the manifest. Avoid requesting unnecessary permissions. Provide clear user-facing explanations for sensitive permissions.
• Apple App Store: Provide usage descriptions in Info.plist for each permission. Explain why the app needs access to sensitive data.
• Both stores reject apps that request permissions without clear purpose or misuse sensitive permissions.
• Follow principle of least privilege: request only permissions essential for app functionality.

Self-Check Question

Your app takes 5 seconds to load this screen. What's likely wrong?

• Requesting multiple permissions at app start blocking UI thread.
• Not handling permission callbacks asynchronously, causing UI freeze.
• Requesting permissions repeatedly without caching granted state.
• Showing permission dialogs without user context, causing delays.

Key Result

Request permissions only when needed and handle user responses asynchronously to maintain smooth UI and fast startup. Declare permissions clearly for store compliance.
