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 APInotifications- a feature module for the notifications featuretoot- 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.
