Since the login flows stopped handing their client over to RustMatrixClientFactory and let finalizeClientCreation() build a fresh one from the SessionData, two problems appeared. The client built by loginWithQrCode() was never owned by anyone: it is not assigned to currentClient, so clear() had nothing to close and the Rust Client stayed open for the whole app lifetime, holding the session stores of the freshly logged in account. It is now tracked in currentClient, and also disposed of when the QR login fails, which is safe because that flow always builds its own client. The client of the session was also built while the login client was still open. Both use the same session paths, so their state and crypto SQLite stores, and the search index when message search is enabled, were opened twice at the same time with no cross process lock to protect them. clear() now runs before the final client is created.

Element X Android
Element X Android is the next-generation Matrix client provided by Element.
Compared to the previous-generation Element Classic, the application is a total rewrite, using the Matrix Rust SDK underneath and targeting devices running Android 7+. The UI layer is written using Jetpack Compose, and the navigation is managed using Appyx.

Translations
Element X Android supports many languages. You can help us to translate the app in your language by joining our Localazy project. You can also help us to improve the existing translations.
Note that for now, we keep control on the French and German translations.
Translations can be checked screen per screen using our tool Element X Android Gallery, available at https://element-hq.github.io/element-x-android/. Note that this page is updated every Tuesday.
More instructions about translating the application can be found at CONTRIBUTING.md.
Rust SDK
Element X leverages the Matrix Rust SDK through an FFI layer that the final client can directly import and use.
We're doing this as a way to share code between platforms and while we've seen promising results it's still in the experimental stage and bound to change.
Status
This project is actively developed and supported. New users are recommended to use Element X instead of the previous-generation app.
Minimum SDK version
Element X Android requires a minimum SDK version of 24 (Android 7.0, Nougat). We aim to support devices running Android 7.0 and above, which covers a wide range of devices still in use today.
Element Android Enterprise requires a minimum SDK version of 33 (Android 13, Tiramisu). For Element Enterprise, we support only devices that still receive security updates, which means devices running Android 13 and above. Android does not have a documented support policy, but some information can be found at https://endoflife.date/android.
Contributing
Want to get actively involved in the project? You're more than welcome! A good way to start is to check the issues that are labelled with the good first issue label. Let us know by commenting the issue that you're starting working on it.
But first make sure to read our contribution guide first.
You can also come chat with the community in the Matrix room dedicated to the project.
Build instructions
Just clone the project and open it in Android Studio. Make sure to select the
app configuration when building (as we also have sample apps in the project).
To build against a local copy of the Rust SDK, see the Developer onboarding instructions.
Support
When you are experiencing an issue on Element X Android, please first search in GitHub issues and then in #element-x-android:matrix.org. If after your research you still have a question, ask at #element-x-android:matrix.org. Otherwise feel free to create a GitHub issue if you encounter a bug or a crash, by explaining clearly in detail what happened. You can also perform bug reporting from the application settings. This is especially recommended when you encounter a crash.
