ListenableFutureUpdateInfoService


abstract class ListenableFutureUpdateInfoService : UpdateInfoService


ListenableFuture-based compatibility wrapper around UpdateInfoService's suspending APIs.

This class is designed for Java consumers who need to implement an UpdateInfoService but prefer using Guava's ListenableFuture over Kotlin Coroutines. By extending this class, host applications can provide the actual network logic by implementing the fetchUpdatesAsync method.

Host Implementation

Host applications (such as the System Updater, Google Play Store, or OEM-specific updaters) written in Java must extend this class and implement the fetchUpdatesAsync method to provide the actual update check logic.

Kotlin consumers should generally prefer extending UpdateInfoService directly to leverage native suspending functions.

Summary

Public constructors

Protected functions

final suspend List<UpdateInfo>

Satisfies the base class Coroutine requirement by delegating to the Future-based implementation.

abstract ListenableFuture<List<UpdateInfo>>

Performs the actual network request to fetch fresh updates from the backend asynchronously.

onClientConnected(packageName: String, callerUid: Int)

Called when a client successfully establishes a session with the update provider.

open Unit
onClientDisconnected(packageName: String, callerUid: Int)

Called when a client explicitly closes its session or its process terminates unexpectedly.

open Unit

Callback for handling exceptions that occur during the update check process.

open Unit

Called when a request completes.

final Boolean
onUnbind(intent: Intent?)

Called by the system when all clients have disconnected from the service's factory interface.

open Boolean

Determines if the local cache is stale and a refresh should be attempted.

open Boolean

Checks if the update check operation should be throttled.

Public constructors

ListenableFutureUpdateInfoService

Added in 1.0.0
ListenableFutureUpdateInfoService()

Protected functions

fetchUpdates

protected final suspend fun fetchUpdates(): List<UpdateInfo>

Satisfies the base class Coroutine requirement by delegating to the Future-based implementation.

fetchUpdatesAsync

Added in 1.0.0
protected abstract fun fetchUpdatesAsync(): ListenableFuture<List<UpdateInfo>>

Performs the actual network request to fetch fresh updates from the backend asynchronously.

Template Method: This method is implemented by the host application (e.g., the System Updater) and invoked by the base class on a background thread. The base class handles concurrency, caching, and rate-limiting.

Preconditions: This method is only called if shouldFetchUpdates returns true and shouldThrottle returns false (the rate limiter allows the request).

Returns
ListenableFuture<List<UpdateInfo>>

A ListenableFuture containing a list of UpdateInfo objects currently available for the device.
