Firebase Firestore for Android

Add Firebase authentication logging to the random app, enable commenting on posts with subcollections, and implement Firestore security rules to control access.

Explore Firebase authentication with email and password by building login and create user screens. Import assets, add icons, and wire onClick actions to navigate between login and create user activities.

Create a new Android user with Firebase authentication using email and password, then store username and server timestamp in a users collection using the user id as the document id.

Learn to authenticate users in an Android app with Firebase: sign in by email and password, handle success or failure, and update UI and menu based on login state.

Adds a comment feature to an Android app by storing comments in a Firestore subcollection under each thought and using a transaction to insert comments and increment the thought's count.

Create a comments adapter and layout to show comments in a recycler view, and define a comment model with user name, time stamp, and text.

Display real-time comments in your Android app by querying Firestore’s thoughts collection and nested comments subcollection, using a snapshot listener, ordering by timestamp, and updating the UI with comment counts.

Learn to implement secure read and write rules in Firebase Firestore for Android, protecting thoughts, comments, and user data with match paths, request.auth checks, and recursive wildcards.

Explore Firestore security rules and learn to enable editing and deleting posts and comments in your Android app, fine-tuning rules to match your implementation.

Set up the Android Firebase Firestore project with starter code and assets, and extend models to track each thought or comment's creator so the owner can edit or delete.

Implement interface-based click listeners for thought and comment options, showing actions only to the owner, and pass the clicked item to the main activity to trigger delete or edit alert.

Implement a custom alert dialog with delete and edit options. Wire the buttons to delete a comment in Firestore and update the thought's comment count via a transaction.

Learn to edit a Firestore comment in an Android app: open update activity, pass IDs and text via intents, and update the comment text in Firestore.

Refine Firebase Firestore security rules to grant read and create for any logged-in user, while granting update and delete only to the comment owner, using request, resource, and data checks.

Delete a thought in Firestore for Android by handling subcollections like comments with a batched delete, ensuring the thought and its comments are removed.

Secure thoughts in Firestore by allowing read and create for all logged-in users, and delete only by the owner, with comments deletions allowed via owner or related thought checks.

Explore next steps after building a real-time Firebase Firestore android app, highlighting categorization, sorting, and live updates. Implement authentication and editing or deleting thoughts, and customize your own project.
