The project is developed under the following build environment.
- Android Studio 2.3.2
Download- Android Studio 1.0–3.1.2 may support Android <2.2, but 2.3.2 is recommended for development as it's simultaneously old and supported.
- Latest AS versions still support Android 2.2 and later (though they are made with 4.1+ in mind)—you can use them if you don't prioritize old Android versions.
- Android SDK of any version (25 recommended)
- It is not required to use an old SDK for developing legacy apps.
- Android 1.0 emulator from the SDK
Download
It is recommended to use AS while contributing; however, you may use another IDE as long as you make the project still usable in AS.
