Detailed Findings

🔴 StateHolderLeak

Static field holds UI/Context reference across configuration changes

Finding #1 — MainActivity

Potential State Holder Memory Leak Detected
Class: com.zcshou.gogogo.MainActivity
Issue: Scenario 2: Static field 'mBaiduMap' of type 'com.baidu.mapapi.map.BaiduMap' in Activity/Fragment is a custom object that may hold UI references. Static fields survive configuration changes.
Fix: Use ViewModel or SavedStateHandle to persist state across rotations.

🟡 ServiceResourceManagementIssueDetector

Service may never stop — missing stopSelf() call

Finding #2 — ServiceGo

⚠� Service may never stop. Consider calling stopSelf() when work is complete.
  Class: com.zcshou.service.ServiceGo
  Method: onStartCommand

🟢 ViewBindingOpportunity

Manual findViewById() calls — ViewBinding migration opportunity

Finding #3 — WelcomeActivity

View Binding Migration Opportunity
Class: com.zcshou.gogogo.WelcomeActivity
Type: Activity
Current Pattern: Manual view lookup
findViewById() Calls:
  • findViewById in checkAgreementAndPrivacy
  • findViewById in showAgreementDialog
  • findViewById in showAgreementDialog
  • findViewById in showAgreementDialog
  • findViewById in showPrivacyDialog
  • findViewById in showPrivacyDialog
  • findViewById in showPrivacyDialog
  • findViewById in onCreate
Benefits of View Binding:
- Eliminates boilerplate findViewById() calls
- Compile-time type safety for view references
- Reduced null pointer exceptions
- Cleaner, more maintainable code
Note: This is a code modernization suggestion, not a memory leak

Finding #4 — HistoryActivity

View Binding Migration Opportunity
Class: com.zcshou.gogogo.HistoryActivity
Type: Activity
Current Pattern: Manual view lookup
findViewById() Calls:
  • findViewById in initRecordListView
  • findViewById in initRecordListView
  • findViewById in initRecordListView
  • findViewById in initSearchView
  • findViewById in lambda$initRecordListView$4$com-zcshou-gogogo-HistoryActivity
