Science Journal allows you to gather data from the world around you. It uses sensors to measure your environment, like light and sound, so you can graph your data, record your experiments, and organize your questions and ideas. It's the lab notebook you always have with you.

Open Science Journal is the core of the Science Journal app with the same UI and sensor code and can be compiled and run on its own.


Building the app

Download the source, go into the OpenScienceJournal directory and run:

./gradlew app:installDebug

Alternatively, import the source code in OpenScienceJournal into Android Studio (File, Import Project).

Note: You'll need Android SDK version 27, build tools 23.0.3, and the Android Support Library to compile the project. If you're unsure about this, use Android Studio and tick the appropriate boxes in the SDK Manager.

The OpenScienceJournal README contains details about the organization of the source code, and the relationship of this published source to the published app.

Google Drive Sync

In order to enable Google Drive Sync, you must first create a Google API project and enable the Drive API for your app. See instructions in the Google Drive API documentation
