## About this fork

The repository you are currenly viewing [**deminearchiver/materium**](https://github.com/deminearchiver/materium) is a **fork** of [**ImranR98/Obtainium**](https://github.com/ImranR98/Obtainium).

In this section the primary differences and deviations compared to the original project are described.

### Self-built only

For now, this fork does not provide any builds. If you want to use this version the app, you'll have to build it from source.

For the time being, it's recommended to use the default "debug" keystore for release builds, as redistribution of builds is not provided.

### Redesign

The redesign of the app is introduced through incremental adoption, which involves introducing changes gradually.

#### New design system

This version of the app features the all-new fresh and shiny [**Material 3 Expressive**](https://m3.material.io) open-source design system created at **Google**.

The [**2025 "Expressive" update**](https://m3.material.io/blog/building-with-m3-expressive) the Material You design system received a big update, which made it look more polished and finished.

Currently, implementation of **Material 3 Expressive** design across the app is considered incomplete, but over time the support for the new design language will improve.

The design changes begin with refactoring the code for a certain UI element, then using legacy styling methods to achieve wanted looks. In order to fully embrace the new design language, it's needed to create new implementations for certain UI elements. This process is slow and tedious, hence the adoption of the new design language will be split a number of migration steps depending on the specific component's complexity. In the process of the redesign, the UI may looks incomplete, but it's the only way to properly apply design changes currently.

#### Markdown styles update

The app uses Markdown to display certain rich text messages, namely changelogs for tracked apps.

While not a part of the Material Design spec, a refresh of the default Markdown styles is urgently needed.

The priority of this change is low, because Markdown is rarely encountered throughout the app normally.

No significant changes were made to Markdown stylesheets yet, because the update is at the design stage.

### Internal changes

This fork features important developer-facing changes, such as:

- Differences in the process of building the app.

- Updated tooling configurations:
  - Removal of Docker support.
  - Framework and SDK updates.

- Code style updates:
  - General improvement of code quality.
  - Application of widely known best practices.
  - Added support for EditorConfig.

- Resolving feature deprecations *(and introducing new ones)*.

- Source code splitting via [internal unpublished packages](https://docs.flutter.dev/packages-and-plugins/using-packages#dependencies-on-unpublished-packages), such as custom implementations of layout, UI, platform interfaces, internationalization, assets.

### Other

Currently, there are a lot of changes not yet covered in this section. The changelist will be updated and more changes will be described.

## Limitations

For some sources, data is gathered using Web scraping and can easily break due to changes in website design. In such cases, more reliable methods may be unavailable.

## Troubleshooting

### App not updating even when a new version is available

- **Check the source settings** — Some sources require additional configuration (e.g., GitHub releases need the correct repository URL format)
- **Check if the source is supported** — Not all sources support version checking equally; some use HTML scraping which may be slower
- **Check the update interval** — By default, apps update every 6 hours. You can change this in app settings
- **Try force-refreshing** — Pull down on the apps list to force a refresh

### Source additions failing with 403 Forbidden

- Some sources block requests from unknown user agents or regions
- GitHub-based sources may need a Personal Access Token if you're hitting rate limits
- Some APK hosts (APKMirror, etc.) may require cookies or specific headers

### Flutter-related issues

- Materium is built with Flutter. If the app crashes on startup, try:
  - Clearing app data and reinstalling
  - Ensuring your Android version meets the minimum requirement
  - Checking if you have the latest Google Play Services

### APK verification failures

- If you see "Signature verification failed", ensure you haven't modified the APK after download
- The SHA-256 hash in the app settings should match the downloaded APK
