Android - Make a Professional Dictionary App from Scratch

Start an Android Studio project for a dictionary app, set min API 17, create an empty activity, and add a settings and exit menu with menu inflation and item handling.

Design the main activity user interface by configuring the toolbar, colors, and styles, adding a coordinator layout for complex view interactions, and wiring a clickable list with a listener.

Design and implement the word meaning activity in an android dictionary app, using a collapsing toolbar, viewpager for steps, pronunciation image, and back navigation, with styling and theming details.

Create full fragments for the word meaning activity, place them in a separate package, and define fragments for definition, synonyms, antonyms, and example within a view pager and toolbar.

Create a view pager adapter and fragment list with four fragments and titles for swipe navigation, then run the app on the emulator to verify collapsing toolbar and back navigation.

Create a settings activity in Android with a toolbar and back navigation, featuring clear history and about items in a vertical layout using card views, launched from main activity.

Learn to integrate a sqlite database into an Android app by using a database browser, adding the database to assets, and creating a SQLiteOpenHelper to access words and history.

Create a database helper class to copy the dictionary database from assets to internal storage, check existence, open in read-only mode, and refresh data by copying in a try-catch flow.

Copy the database in the background with an async task to prevent freezing; show a dialog with a progress bar while copying from assets to phone memory, then open database.

Develop an audition adapter for the search view to provide suggestions as you type and launch the word meaning activity with the selected word via a bundle.

Add a search view listener to fetch meanings, synonyms, and antonyms from the words table, display up to 40 suggestions as users type, and alert when a word isn't found.

Finish up the word meaning activity by retrieving word data from the main activity, querying the database for meaning, synonyms, antonyms, and example, and enabling text-to-speech pronunciation.

Attach a recycler view to the main activity, design a history item layout with a clickable card and ripple effect, and implement a Java class to manage history entries.

Create a Java recycler adapter for history list, implement a history view holder, bind words to text views, and launch the word meaning activity via an intent extra on click.

Initialize and link a recycler view with a history list in the main activity, fetch and display distinct history items from the database, and handle empty history ui on resume.

Implement a clear history feature in the Android app by adding a delete history function in the database helper, prompting a confirmation dialog, and reflecting changes in the history list.

Modify the history list by adding a definition field and bold text. Implement input validation with a regex to prevent crashes from single quotes and refine the history query.

Learn to enable sharing words from other apps into your Android dictionary app by handling ACTION_SEND, text/plain mime type, and extracting the shared word for instant definition.
