Instruction Create a native application for Android that allows the user to store and manage tasks. Your application should allow user to create tasks by category that user chooses (work, school, shopping, groceries etc.). Every task taken should store a date and time it was created and the due date/time. User should be allowed to sort tasks by title or by date/time that were created. User should also be allowed to search for specific task by their name or by keyword that may be contained in a task name. User should be allowed to take a picture (or use a picture that was previously taken) and store it as part of a task. Multiple pictures should be allowed to be associated with the same task. The application should also have the following features:

User should be able to change the status of the task from "incomplete" to "complete" and remove the tasks entirely.

User should be allowed to record audio and attach it to the task and/or use a pre-recorded sound on the device. User can create/edit/delete categories for tasks. The purpose of these categories is to organize tasks. A single task (parent) can contain smaller tasks (sub-tasks or children). Parent task cannot be "complete" if not all the child-tasks are "complete".
