The deleteTask() method is called when the "Delete" menu item is tapped. This needs to be implemented.

Describe the solution you'd like
Retrieve the selected todo item from the adapter and delete it from the allTasks list.
Note that these the functions (createNewTask(), deleteTask(), etc.) in the main activity modify only the allTasks list.

Please describe the feature you want this project to offer
The addAllTasks() and removeTasks() methods need to be implemented.

Describe the solution you'd like
The addAllTasks() method adds all the tasks in the passed list to the database. The previous records in the database have to be deleted before that, (in case some tasks were updated) which is done by the removeTasks() method.
These functions interact directly with the SQLite database.

The RecyclerView Adapter that displays the todo items in the Main Activity should be implemented.

Describe the solution you'd like
The Adapter should ensure that the items are single-selectable (i.e., one of the items on long press will be selected and only one item should be selected at a single time). When an item is selected, a tick symbol should appear beside it.

The logic in Main Activity to create a new task should be implemented.

Describe the solution you'd like
Use CreateActivity to create a new todo task. This issue handles the main activity part of the code.
Note that these the functions (createNewTask(), deleteTask(), etc.) in the main activity modify only the allTasks list.
