Android Persistence Standards

Priority: P0

Implementation Guidelines

Room

  • Async: Return 
    Flow<List<T>>
    for queries, use 
    suspend
    for Write/Insert.
  • Entities: Keep simple 
    @Entity
    data classes. Map to Domain models in Repository.
  • Transactions: Use 
    @Transaction
    for multi-table queries (Relations).

DataStore

  • Usage: Replace 
    SharedPreferences
    with 
    ProtoDataStore
    (Type-safe) or 
    PreferencesDataStore
    .
  • Scope: Inject singleton instance via Hilt.

Anti-Patterns

  • No IO on Main Thread: Room handles dispatchers, but verify Flow is collected off-main.
  • No @Entity in UI Layer: Map to Domain or UI models in Repository.
