Highlighter 📱

Description 🖼️

Highlighter is an Android application for gathering texts (referenced in the application context as "quotes") from other applications (for example, a sentence from an article read on a website, in the browser), attaching them labels, and saving them locally or in Notion.

The application has the following functionalities:

• saving quotes from other application via the context menu;
• edit of the details of the quote;
• filtering of the quotes by the content or by labels;
• deletion of quotes;
• upload/download of quotes to/from a collection in Notion;
• statistics activity with details about quotes count, the ranking of the used labels, and chart with quotes count per day;
• settings activity;
• activity with details about the application;
• snackbar usage for new events (successes and errors); and
• dark mode.

Observation: As the official Notion API was not integrated, the Android application requires a Python 3 proxy server that creates the requests to Notion.

Setup 🔧

1. Duplicate the Notion template that will store the quotes
2. Set up ngrok by following the installation guide
3. Set up the proxy server

cd api
pip3 install -r requirements.txt
python3 api.py
ngrok http 5000

4. Open the Android Studio project
5. Create a secrets.properties file in the build file with a MAPS_API_KEY key storing the Google Maps API key retrieved from Google Cloud Platform
6. Build the project and deploy the application to your Android phone

Future Improvements 🔜

• Replacement of the unofficial Notion API with the official one, taking out the need for a proxy server
• Testing and refactoring of the user interface to imply responsiveness on all devices
• Replacement of the AsyncTalk class, deprecated in API level 30
• Removal of the Google Maps component
