## What it is
Tray is an Android library that replaces SharedPreferences with a ContentProvider-backed key-value storage that works reliably across multiple processes. It adds metadata tracking, modular preferences, versioned upgrade/migration hooks, and SharedPreferences import support.

## Use cases
- store key-value preferences safely across multiple Android processes
- replace SharedPreferences in a multiprocess Android app
- migrate existing SharedPreferences data to a new storage layer
- version and upgrade app preferences between app releases
- manage app settings in modular preference groups

## When to choose
- your Android app accesses preferences from multiple processes
- you need migration and versioning for stored preferences
- you want SharedPreferences import and auto-backup support

## When to avoid
- you need an actively maintained library (project is deprecated)
- your app is single-process and standard SharedPreferences suffices
- you prefer modern alternatives like DataStore

## Facets
- artifact type: library
- maturity: abandoned
- function: database, configuration-management
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: sharedpreferences, multiprocess, key-value-storage, contentprovider, deprecated, android, mobile
