Detailed Findings

🔴 ThreadedUIReference

Worker thread captures Activity/Fragment/View reference

Finding #1 — ChatFragment

Scenario 1: Worker thread holds UI object reference
Class: de.stephanlindauer.criticalmaps.fragments.ChatFragment
Method: void handleSendClicked()
Statement: $r8 = new de.stephanlindauer.criticalmaps.handler.PostChatmessagesHandler
Captured UI objects:
  - r0 : de.stephanlindauer.criticalmaps.fragments.ChatFragment
Risk: UI object will be kept in memory until thread completes
Fix: Use WeakReference or avoid passing UI objects to worker threads

🟡 ServiceResourceManagementIssueDetector

Service may never stop — missing stopSelf() call

Finding #2 — ServerSyncService

ℹ� Best Practice: Service relies on stopSelf(). For robustness, also call stopForeground(true) in onDestroy().
  Class: de.stephanlindauer.criticalmaps.service.ServerSyncService
  Method: N/A
