PR Summary

• Enhancement of behavior in the Android Manifest: A new attribute android:enableOnBackInvokedCallback has been included in the application definition in AndroidManifest.xml, allowing us to further customize what occurs when the back button is tapped on Android devices.

• Expanding functionality on screen transitions in ScreenActivity.kt: Several methods have been added to control the 'Back' button's behavior according to the current state of the application. We've removed some calls to return to the previous screen, replacing them with a more thorough approach that checks the current app status and provides a more consistent user experience.

• Replacing the use of native Back functions across fragments: In multiple Fragment files (like EditRepositoryFragment.kt, RepositoryFragment.kt, SettingsFragment.kt), calls to the native onBackPressed() function are replaced to take advantage of our newly implemented custom back button handling.

• Further control of 'Back' button in TabsFragment.kt: More control over the 'Back' button action depending on the current state in TabsFragment.kt, including calculating the appropriate action based on the state of the application and updating it as needed. Similar to the functionality added in ScreenActivity.kt.

With the new implementations in this pull request, back button behavior will be more predictable and enhance application usability, especially when users navigate through different screens or fragments in the application. Having a comprehensive control over the back button across all activities ensures a smooth navigation and more accurate actions corresponding to users' expectations.

@Iamlooker I fixed the search box behaviour, the change is fully functional.
Do you have any other test in mind other than the ones shown in the video?

Nope

Thank you for your contribution 😃

I will merge after testing myself
