Refactor/Docs not opening fixed.

[icanerdogan]

🎯 Goal

The goal of this change is to fix a NullPointerException in the app, specifically caused by an attempt to invoke the toString() method on a null object. This was preventing the application from opening, causing it to crash immediately. After fixing this issue, the app is now able to open and function as expected.

🛠 Implementation details

The fix involved identifying the null object reference that caused the NullPointerException. By adding null checks and ensuring that the object is initialized before invoking any methods, we prevented the crash. The updated code now gracefully handles null values, allowing the app to proceed without errors.

🎨 UI Changes

There were no UI changes involved in this fix as it was related to backend functionality. However, the app's stability has significantly improved, leading to a better user experience.

Before	After

No visible UI changes were made, but the app is now stable and can open without crashing.

🧪 Testing

This change can be tested by launching the app on a device or emulator and verifying that it no longer crashes on startup. If the app opens successfully and functions as expected, the issue has been resolved.

                    applicationInfo.nonLocalizedLabel?.toString() ?: "UnknownApp"
                } else {
                    context.getString(stringId) ?: "UnknownApp"
                }
              } else { "UnknownApp" }
