Mammut

Mammut is a multi-account capable Mastodon client for Android. It's built with offline support from the get-go for home and local timelines, and will soon allow for offline toot queuing. The key capabilities so far are:

• Multi-account support, including more than one account per instance
• Offline support
• Full theming capabilities, including 2 light and 2 dark themes
• Full support for custom emoji, including adding them when composing a toot

App Structure

Modules

Mammut is structured into a number of modules. This allows good separation of concerns, and faster build times.

• app - the main app module for Mammut. This consumes all other modules.
• base - the base module for feature modules. This includes all basic required dependencies for features, as well as a set of base classes for features to extend from.
• data - this module contains all data-related classes for the app, including database definitions, as well as repository implementations.
• instances - a simple wrapper library for the instances.social REST API
• notifications - a feature module for the notifications feature
• toot - a feature module for toot composition

App Architecture

Mammut is built with a number of different architecture considerations in mind:

• The Repository Pattern - this allows abstraction of the source of data from other components in the app. This pattern is especially useful when trying to implement offline support.
• MVVM - Standard MVVM as recommended by Google is used throughout
• Conductor - a replacement for Android Fragments that allows easier navigation, as well as a much nicer transitions framework.

Building from source

Here's the steps to build yourself a debug variant of Mammut.

• Get yourself an API token from the instances.social token portal. Remember, this is meant to be secret! Don't commit this to source control.
• In keys.gradle, replace the help message with your token. Be careful to not remove any "s OR \s. It should look something like this:

ext.INSTANCES_SECRET = "\"GRERU43534J..324\""

• Open up a terminal and navigate to where you've cloned the project. Run this command:

./gradlew installDebug

That's it! Look through your installed apps for Mammut, with a white icon.

Disclaimer

This project is under heavy development. Things will probably change substantially between updates - apologies in advance. You can find it in beta on the Play Store here.
