Implementation Plan: Direct Tracking Tab Selection (ATT-409)

Refactor the navigation drawer to show the Activity Type selection dialog directly, fulfilling REQ-SET-051 and resolving the fatal ActivityNotFoundException when launching the configuration cockpit.

User Review Required

Important

• Navigation Change: This change will remove the intermediate ConfigTrackingTabsActivity from the drawer flow. Instead, a modal dialog will appear over the current screen to select the sport type.
• In-App Configuration: Selecting a sport will now replace the current fragment with the TrackingTabsFragment in configuration mode, keeping the user within MainActivityWithNavigation instead of jumping to a separate Activity.

Proposed Changes

1. UI Layer: Navigation Drawer Refactor

[MODIFY] MainActivityWithNavigation.java

• Requirement: REQ-SET-051 (Direct Tracking Tab Selection)
• Test: TST-NAV-003 (Direct Config Navigation)
• Changes:
  • Update the drawer_tracking_layouts case in onNavigationItemSelected to call ActivityTypeSelectionHelper.showSelectionDialog().
  • In the onTypeSelected callback, replace the current fragment with TrackingTabsFragment.newInstance(activityType).

2. Cleanup: Remove Redundant Components

[DELETE] ConfigTrackingTabsActivity.kt

[DELETE] ConfigTrackingTabsFragment.kt

[MODIFY] AndroidManifest.xml

• Remove the <activity> registration for ConfigTrackingTabsActivity.

Verification Plan

Manual Verification

1. Drawer Interaction: Open the navigation drawer and tap "Tracking Layouts".
2. Dialog Visibility: Verify that the "Select Activity Type" dialog appears immediately.
3. Selection Flow: Select "Cycling".
4. Fragment Transition: Verify that the screen switches to the tracking configuration cockpit for Cycling.
5. Navigation Consistency: Verify that pressing "Back" returns to the previous top-level fragment correctly.
