Note: Trackr uses version 7 of Gradle, which currently requires Android Studio Beta or Canary.
Trackr is a sample task management app used to explore common UI patterns from the perspective of supporting accessibility. Trackr is currently under development.
Using Trackr, end users can discover, create, and edit tasks; they can assign tasks to team members and they can associate different tags with each task. Users can archive a task by swiping right and they can modify a task's priority by dragging it up or down.
Developers are encouraged to explore Trackr using an accessibility service like Talkback or Switch Access; developers are also encouraged to try out the various accessibility settings found on their devices (see Settings > Accessibility on most Android phones) when using Trackr. If you have any suggestions, please create an issue (see below).
Trackr is designed with the goal of allowing all users to enjoy its core functionality, including users with disabilities who may interact with their devices using accessibility services. So, for example, while blind and low vision users or users with manual dexterity issues may not be able to perform the swipe gesture to archive an item or drag and drop items to reorder their priority, they should nonetheless be able to access the archive and reorder functionality through the accessibility service they are using.
The following accessibility APIs (non exhaustive list) are showcased in this sample:
ViewCompat#addAccessibilityAction(): to surface functionality like swipe-to-archive, drag and drop, etc.
ViewCompat#performAccessiblityAction(): used in testing.
ViewCompat#replaceAccessibilityAction(): used to customize the label for associated with an action.
ViewCompat.setStateDescription(): used to specify state associated with a view.
AccessibilityManager#getRecommendedTimeoutMillis(): used to specify the timeout for ephemeral content.
This project uses the Gradle build system. To build this project, use the
gradlew build command or use "Import Project" in Android Studio.
To run tests, run gradlew test

We are continuously working to improve this sample and add new features. If you have suggestions for improvement or if you encounter a problem, please provide feedback to us via the issue tracker. When creating an issue, try to include the following:
- The device manufacturer and model
- The Android build running on the device
- If using an accessibility service (for example a screen reader), the name and version number of that service
- A description of the issue; include screenshots/screencaps if you think they'll help us understand the problem
