Continue building the upcoming tasks tab in Kivy by adding a vertical scroll view, a box layout, labels with icons, padding, color, and a grid layout to render upcoming features.

Build and style the upcoming task widget in a Kivy task manager by deriving it from the existing task widget, adding a two-day variant, and adjusting layout, color, and labels.

Adjust the upcoming widget by tweaking left padding, color to black, and label sizes; refine top padding and navigation bar as you approach database integration and menu button positioning.

Implement a main screen navigation drawer in a kivy app by importing the navigation drawer widget, wrapping main content, and wiring toggle button to open it at 70 percent width.

Add new tasks in a Kivy task manager by wiring on release to open and close the popup, and remove the new button once enough tasks exist.

Learn to set up a dedicated database folder and implement a sqlite3-backed database in a Kivy app, including creating tasks and users tables with Python.

define an add_user function to add a new user to the database, connect with a simple utility, hash the password with SHA-256, and use a parameterized insert.

Create and authenticate a user by connecting to the database, querying the users table with a cursor, hashing the password, fetching results, and returning true or false based on validity.

Develop and test task management in a kivy app by adding, updating, and deleting tasks through a single database connection to the trusts database, using task name and date fields.

Test a kivy task manager database by adding, retrieving, updating, and deleting tasks with a defined date format using SQL, and explore list versus table structures in the main program.

Concatenate the date and time into a single object, then add the task to the database and update the view only after a successful insert.

Delete a task from the database and retrieve all tasks to display on the main screen of the task manager, updating both the database and the view.

Secure the main screen task list by adjusting widget sizing, using the window as the scroll container, and delaying init with a clock; plan to separate today’s tasks from upcoming.

Develop a task management feature by classifying tasks into today and upcoming using Python datetime, date parsing, and date comparisons, preparing for a two-day panel.

Learn date handling in a Kivy task manager: parse date strings, classify tasks as today or upcoming, and separate and size the main screen tasks.

Fix date handling in the task manager app by normalizing date picker output, parsing dates, and displaying precise dates and times for upcoming and two-day tasks.

Build main screen for a Kivy task manager using a box layout with a back button, a today label, and task entries, and manage screen transitions with a screen manager.

Fix the main screen layout by correcting orientation, aligning labels and buttons, and adjusting dynamic heights with size hints, padding, and rounded values for a clean task manager UI.

learn to implement a kivy main screen for viewing tasks by building a view task panel, with a non-editable name field and date-time boxes.

Explore viewing and editing tasks in a Kivy-based to-do app by leveraging a shared task class, using text inputs for name, date, and time, and refining UI colors.

Reuse the new task model to enable updating a task in a Kivy task manager. Adjust button behavior and introduce an update task flow inside a submit wrapper box layout.

Develop the update task flow in a Kivy app by binding the on_release event to an update callback and saving new task values to the database (name, date, time).

Fix the main screen update flow in a Kivy task manager using the original task name from the database. Ensure the update triggers correctly and dismiss the modal after save.

Route future tasks to the upcoming screen instead of the two-day screen by cleaning dates and assigning tasks as upcoming.

Set up Google AdMob account, configure country and currency, and create banner and interstitial ad units with their IDs to enable ads in your Kivy task manager app.

Set up a scalable build environment on a DigitalOcean server to create an API, install the Android SDK, and run a setup script using free credits.

Log into a digital ocean server via ssh, create a non-root user, and grant sudo privileges. Set up sftp transfers and prepare the Android build workflow on the server.

Set up a mobile build server for a task manager app by creating a build and manager API, editing the buildozer.spec with nano, and configuring the Android SDK and requirements.

Learn by building a kivy task manager apk on a remote server, including zipping the project, transferring files, updating android sdk, and building the apk with buildozer.

Learn to install and test an Android app using adb logcat. Identify and fix a missing date time picker in requirements, then rebuild and push the APK to your device.
