Introducing the home screen layout feature! Now, users have the ability to personalize their experience by disabling the app drawer and arranging apps directly on their home screen.
- closes : #4323
https://github.com/GrapheneOS/os-issue-tracker/issues/2601
I did not find any issue reported upstream, but I can confirm that this
bug exists on Moto App Launcher (the launcher on Motorola's devices),
which seems to imply this is a bug in AOSP itself. I had asked
@agnostic-apollo about this is a bug, and he said that this is a bug in
Android's libraries itself
- Introduced "Caddy" functionality to organize apps within the app drawer.
- Allows grouping of applications for better accessibility and user experience.
- Serves as a foundational feature for enhancing app drawer usability.
* feat: Allow re-arranging popup menu items
* Refactor draggable preferences
* Refactor options pop-up drag and drop view
- Move to new screen
- Separate preview and options
This commit addresses a NullPointerException that occurs when updating
widget options in the WidgetSizes class. The fix includes:
- Adding null checks for sizeOptions and currentOptions
- Comparing new sizes with current sizes before updating
- Catching and logging exceptions during widget option updates
- Returning null from getWidgetSizeOptions if it fails to create a valid Bundle
These changes should resolve the "Attempt to invoke virtual method 'void
android.os.Bundle.putAll(android.os.Bundle)' on a null object reference" error
and improve the robustness of widget size updates.

- Adding null checks before calling methods on mWidgetHost
- Ensuring the listening flag is always updated, even if an exception occurs
This should resolve the "java.lang.NullPointerException: Attempt to read from
field 'com.android.server.appwidget.AppWidgetServiceImpl$ProviderId'" error
and improve overall stability when dealing with widgets

- Revised migrate method to process each screen independently, preventing
merging of items from different screens
- Implemented dynamic item placement logic to maintain relative positions
when changing grid sizes
These changes address issues with item positioning, screen merging, and
maintain a more intuitive layout when changing grid sizes. The migration
now respects the original screen structure and preserves relative item
positions as much as possible
