Development notes (v3.x.x)

My original version of BetterUntis had many design and performance flaws. As a result, development became increasingly more difficult. I came to the conclusion that it was best to scrap the project and start over from scratch.

Although I reused some parts of the original code, my plan was to entirely switch to Kotlin. Kotlin has many features and libraries that immensely help to communicate with the Untis API and process the timetable data.

Another major change is the use of a custom WeekView (based on Till Hellmund's fork of Android-Week-View) for the timetable display. This also improved performance by a lot.

Project Git Structure

I established a simple system to manage this Git repository. Basically, there are two main branches: master and develop. They both are permanent and cannot be deleted.

Branch: master

This branch always and only contains the latest release version. This includes alpha/beta releases.

Branch: develop

This branch contains the current development version. Small changes and fixes can be committed directly to this branch.

When it reaches a state ready to release, it can be merged into the master-branch and a new release can be published.

Other branches

Especially bigger features which require multiple commits should branch off develop and merge back into it. These should be named in a way to describe the feature as clearly as possible.

These branches have a limited lifetime. After the last merge back into develop, they should be deleted if no longer needed.


Your help is greatly appreciated, but first please read the following sections to prevent common mistakes:

Translating into another language

If you haven't already, sign up for an account at . You can then navigate to the BetterUntis translation project.

Select your desired language (or click the “Start new translation“ button at the bottom) and look at "Strings status". All categories marked in red are areas where translations are missing or potentially incorrect. Click on them to start translating.

Your translation will then be automatically included in the next release of BetterUntis.

Implementing new features / Fixing bugs

Anything that requires you to perform code changes should be done on the develop branch. Pull requests should always be based on this branch, except for larger, experimental or incomplete features. These can be on their own, new feature branch.

Please do not submit pull requests that merge into the master branch, except for changes that only affect the repository on GitHub (e.g. changes).
