Better "unavailable" handling in PersonalID biometric config page #3265
Conversation
…g-on-debug-mode Disabled Firebase Performance monitoring in Debug mode
Translation changed for start registration string
…errors until relevant PIN/biometric button is pressed. Split the two error messages apart for better localization. Cleaned up a couple code warnings in biometric config page along the way.

📝 WalkthroughWalkthroughThis set of changes focuses on refining the error handling and messaging for PersonalID configuration flows, particularly around PIN and biometric security mechanisms. The build configuration is updated to hardcode certain Google service keys. Across multiple language resource files, a generic error message for unavailable security features is replaced with two explicit messages for PIN and biometric unavailability. In the Java code, the handling of activity results for PIN and biometric configuration is refactored, with the Sequence Diagram(s)sequenceDiagram

Learning: PR #3048 "Phase 4 Connect PR" introduces a substantial feature called "Connect" to the CommCare Android app, which includes messaging, job management, delivery tracking, payment processing, authentication flows, and learning modules. It follows a modern architecture using Navigation Components with three navigation graphs, segregated business logic in Manager classes, and proper database persistence.

Learning: In CommCareSetupActivity.java, the call to installFragment.showConnectErrorMessage() after fragment transactions is intentionally unguarded with null checks.

Learning: In the CommCare Android app, for non-critical convenience features like phone number auto-population, exceptions should be logged but fail silently when there's a manual fallback available. This approach prevents app crashes while maintaining the ability to debug issues through logs.

Learning: In the CommCare Android codebase, the navigation graph for Connect messaging (nav_graph_connect_messaging.xml) intentionally uses channel_id as the argument name in the connectMessageFragment, despite using channelId in other parts of the same navigation graph. This naming difference is by design in the refactored code.

Timestamp: 2025-01-21T18:19:05.799Z
Learning: In ConnectIdPasswordVerificationFragment, when creating a ConnectUserRecord, it's acceptable for payment information (paymentName and paymentPhone) to be empty strings if the server response doesn't include payment info in the CONNECT_PAYMENT_INFO field.

Timestamp: 2025-05-22T14:26:41.341Z
Learning: In SelectInstallModeFragment.java, the showConnectErrorMessage method intentionally omits null checks because it's called at a specific point in the startup flow where UI is guaranteed to be loaded. It's designed to crash if activity or view is null to make potential issues immediately visible rather than hiding them with defensive programming.

Learning: PR #3048 "Phase 4 Connect PR" introduces a substantial feature called "Connect" to the CommCare Android app, which includes messaging, job management, delivery tracking, payment processing, authentication flows, and learning modules. It follows a modern architecture using Navigation Components with three navigation graphs, segregated business logic in Manager classes, and proper database persistence.

Learning: In CommCareSetupActivity.java, the call to installFragment.showConnectErrorMessage() after fragment transactions is intentionally unguarded with null checks. This follows the app's design pattern where critical error paths prefer immediate crashes over silent failures, making potential issues immediately visible during development rather than hiding them with defensive programming.

Learning: In the CommCare Android app, for non-critical convenience features like phone number auto-population, exceptions should be logged but fail silently when there's a manual fallback available. This approach prevents app crashes while maintaining the ability to debug issues through logs.

30-30: LGTM! Method signature simplification supports improved error handling.The removal of the
Intent dataparameter fromhandleFinishedPinActivityis consistent with the PR's goal of streamlining PIN and biometric error handling. This simplification suggests the Intent data is no longer needed for processing activity results, which aligns with the improved error messaging approach.app/res/values-es/strings.xml (1)
444-445: Excellent localization improvement for PersonalID error handling.The separation of generic security error messages into specific PIN and biometric availability messages greatly improves user experience. The Spanish translations clearly communicate the issue and provide actionable guidance for users to resolve hardware unavailability problems or try alternative devices.
This change directly supports the PR's main objective of providing better error handling in the PersonalID biometric configuration page.
app/res/values-sw/strings.xml (1)
451-452: Granular error strings introduced – looks goodThe new PIN / biometric-specific messages follow existing naming conventions and match the pattern added in the default strings file, so they’ll resolve cleanly at runtime.
Please just double-check that:
- every call site in
PersonalIdBiometricConfigFragment/BiometricsHelpernow references
personalid_configuration_process_*_unavailable_message, and- the legacy generic key
personalid_configuration_process_failed_security_subtitleis no longer referenced (or kept intentionally).No other issues spotted.
app/res/values-pt/strings.xml (1)
451-452: New PIN & biometric unavailability strings added correctlyTranslation keys and wording are consistent with the default resources and other locales. Good separation for localization.
As with the Swahili file, please verify that:
• code paths now point to these new keys, and
• any obsolete reference to the old generic subtitle has been removed.Otherwise, all set.

607-608: LGTM! Improved error messaging for better user experience.The separation of generic security unavailability into specific PIN and biometric error messages enhances user clarity and supports better localization. Both messages provide actionable guidance and follow consistent naming conventions.

220-228: LGTM! Improved validation with centralized security type checking.The new
checkForValidSecurityTypemethod provides clear, centralized validation for security lock types. It properly handles both empty and invalid values using existing constants, which improves code maintainability and consistency.
230-232: LGTM! Simplified exception method signature.Removing the unused
Activityparameter makes the method more focused and cohesive. The method maintains its core functionality of throwing descriptive exceptions for invalid security types.
234-236: LGTM! Clean method for PIN-specific error messages.The method provides a straightforward way to retrieve the localized PIN hardware unavailability error message, supporting the improved error messaging approach introduced in this PR.
238-240: LGTM! Consistent biometric error message retrieval.The method mirrors the PIN error method structure, providing consistent API design for retrieving localized biometric hardware unavailability messages. This completes the improved error messaging approach.
app/src/org/commcare/fragments/personalId/PersonalIdBiometricConfigFragment.java (9)
65-68: LGTM: Proper validation integration.The addition of
BiometricsHelper.checkForValidSecurityType()call in onCreate aligns with the PR's objective to improve error handling. This validates the required lock type early in the fragment lifecycle, which is a good defensive programming practice.
129-131: Minor: Uninitialized variables could cause compilation issues.The variables
title,message, andfingerprintButtonare now declared without initialization, but all code paths in the subsequent if-else chain properly assign values to these variables, so this change is safe.
164-164: Improved visibility logic for UI separator.The simplified logic for showing the "or" separator now only depends on the presence of a PIN button, which makes the code more readable and maintainable.
187-199: Excellent refactoring: Switch statement improves readability.The refactoring from if-else chains to switch statements significantly improves code readability and maintainability. The dedicated handling for each
ConfigurationStatuscase makes the logic clearer.
202-207: Well-structured error handling method.The dedicated
showBiometricNotAvailableError()method properly:
- Retrieves the appropriate error message using
BiometricsHelper.getBiometricHardwareUnavailableError()- Reports analytics for failure tracking
- Logs the error for debugging
- Navigates to the appropriate error display
This aligns perfectly with the PR objective to show errors only when users interact with the buttons.
209-212: Good separation of concerns with authentication initiation.Extracting the biometric authentication logic into a dedicated method improves code organization and reusability. The method properly passes the required parameters including the PIN fallback flag.
218-230: Consistent refactoring for PIN button handling.The PIN button click handler follows the same improved pattern as the fingerprint handler, using a switch statement for better readability and maintainability.
233-238: Consistent error handling for PIN unavailability.The
showPinNotAvailableError()method mirrors the biometric error handling approach, ensuring consistent user experience and error reporting across both authentication methods.
244-244: handleFinishedPinActivity signature update verified and completeAll call sites have been updated to use the new two-parameter signature. No further changes are required.

There was a problem hiding this comment.
Security concern: Hardcoded API keys in source code.
Hardcoding sensitive configuration values like GOOGLE_SERVICES_API_KEY and FIREBASE_DATABASE_URL directly in the build script exposes them in the source code repository. This creates security risks as these credentials become visible to anyone with repository access.
Consider using environment variables or secure configuration management instead:
- //GOOGLE_SERVICES_API_KEY = project.properties['GOOGLE_SERVICES_API_KEY'] ?: ''
- GOOGLE_CLOUD_PROJECT_NUMBER = '768065119425L'
- //FIREBASE_DATABASE_URL = project.properties['FIREBASE_DATABASE_URL'] ?: ''
- GOOGLE_SERVICES_API_KEY='AIzaSyBV76f3obt9IgMDfvphWX8ZM91z8d7rK2w'
- FIREBASE_DATABASE_URL='https://commcare-a57e4.firebaseio.com'
+ GOOGLE_SERVICES_API_KEY = project.properties['GOOGLE_SERVICES_API_KEY'] ?: ''
+ GOOGLE_CLOUD_PROJECT_NUMBER = project.properties['GOOGLE_CLOUD_PROJECT_NUMBER'] ?: -1L
+ FIREBASE_DATABASE_URL = project.properties['FIREBASE_DATABASE_URL'] ?: ''📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In app/build.gradle around lines 192 to 204, the GOOGLE_SERVICES_API_KEY and
FIREBASE_DATABASE_URL are hardcoded, exposing sensitive credentials in the
source code. Remove these hardcoded values and instead retrieve them from
environment variables or secure project properties using syntax like
project.properties or System.getenv. Update the build script to fallback to
empty strings or defaults if these variables are not set, ensuring credentials
are not stored directly in the repository.

Product Description
When there is an issue with the user's biometric or PIN hardware being unavailable to the app, the user will see the error message when they click the button corresponding to each option, rather than when the page loads.
Technical Summary
Changed biometric config page not to report "unavailable" errors until relevant PIN/biometric button is pressed.
Split the two error messages apart for better localization.
Cleaned up a couple code warnings in biometric config page along the way.

Safety story
Tested locally, although I don't have a device that fails the hardware check so could only test greenlight path.
Automated test coverage
None
QA Plan
Would be great to test recovery as a Connect user with a device that gives the "fingerprint unavailable" error to make sure the user can successfully proceed with the PIN option, but that may not be possible since this error is not easily reproducible.
