Navigation: v2.6.0-alpha05

February 8, 2023

New Features

• NavController.popBackStack(route), NavController.getBackStackEntry(route), NavController.clearBackStack(route) now all support routes with arguments partially or fully filled in. Note that the arguments have to be an exact match with the entry's arguments. (Iebd28, Ic678c, I3b37b, b/257514373)
• The FragmentNavigator now uses the transition APIs when navigating and popping NavBackStackEntries. This means that the NavBackStackEntry Lifecycle will now wait for the entering and exiting fragment special effects to complete before moving their final Lifecycle.State. (I3cb19, b/238686802)
• The DialogFragmentNavigator now uses the transition APIs when navigating and popping NavBackStackEntries. This means that the NavBackStackEntry Lifecycle will now wait for the DialogFragment Lifecycle to move to DESTROYED before moving to DESTROYED itself. (I53ee5, b/261213893)

API Changes

• NavigatorState now provides the prepareForTransition API to allow Navigators to move NavBackStackEntries to intermediate Lifecycle.States. (I42c21, b/238686802)
• You can now access the back stack associated with a NavGraphNavigator or a ComposeNavigator via a backstack property. ComposeNavigator also now exposes the onTransitionComplete() callback to mark a NavBackStackEntry that has executed a navigate or popBackStack operation as complete. (I02062, I718db, b/257519195)

Bug Fixes

• Navigator state will now no-op when using the push/popWithTransition APIs and the entry is already being handled. (Iadbfa, b/261213893)
• When using launchSingleTop with a nested NavGraph all destinations starting from original destination to its startDestination will only be properly added to the top of the backstack. (Id4bea, b/253256629)
• Navigation will now properly replace the DialogFragment instance when navigating to the same destination with the launchSingleTop flag set to true. (I45b5a, b/149572817)
• Navigation SafeArgs will no longer cause a compilation error when using arguments that are exactly 19 characters long. (Id60bc, b/257110095)

Paging: v3.2.0-alpha04

February 8, 2023

androidx.paging:paging-*:3.2.0-alpha04 is released. Version 3.2.0-alpha04 contains these commits.

Paging Testing

• The paging-testing artifact now contains a asPagingSourceFactory method to create a pagingSourceFactory from a Flow<List<Value>> to be supplied to a Pager. Each List<Value>> emitted from the Flow represents a generation of Paged data. This facilitates paging tests on, for example, PagingData transformations by faking a data source for the Pager to collect from. (I6f230, b/235528239)

• The paging-testing artifact has been expanded with new APIs suitable for verifying the data contained with a Flow<PagingData<T>> is correct. This can be used, for example, to assert the output of a Flow<PagingData<T>> from your ViewModel layer.

  This is done via the asSnapshot Kotlin extension on Flow<PagingData<Value>>, which translates the Flow<PagingData<Value>> into a direct List<Value>. The asSnapshot lambda allows you to mimic the UI of your app via APIs such as scrollTo or appendScrollWhile in a way that is repeatable and consistent so that you can verify the snapshot of data is correct at any point in your set of paged data.

  // Create your ViewModel instance
  val viewModel = …
  // Get the Flow of PagingData from the ViewModel
  val data< Flow<PagingData<String>> = viewModel.data
  val snapshot: List<String> = data.asSnapshot {
    // Each operation inside the lambda waits for the data to settle before continuing
    scrollTo(index = 50)
  // While you can’t view the items within the asSnapshot call,
  
  // you can continuously scroll in a direction while some condition is true
  
  // i.e., in this case until you hit a placeholder item
  
  appendScrollWhile {  item: String -> item != “Header 1” }
  
  }
  
  // With the asSnapshot complete, you can now verify that the snapshot
  
  // has the expected values
  
  

  asSnapshot is a suspend method that is expected to be run within runTest. See Testing Kotlin coroutines on Android for more information. (I55fd2, I5bd26, I7ce34, I51f4d, I2249f, Id6223, Ic4bab, Ib29b9, Ic1238, I96def, b/235528239)

API Changes

• UI calls to getItem and peek in AsyncPagingDataDiffer and PagingDataAdapter are now correctly marked as only callable on the Main thread. (I699b6)
• Removed wildcards from generic types used by TestPager, making it easier to consume the results of those methods in code written in the Java programming language. (I56c42)

Important changes since 2.7.0

New Features

• An ability to update WorkRequests in a non-intrusive way was added, preserving original enqueue time, chaining etc. See detailed blogpost about this feature, as well as javadocs for WorkManager.updateWork and ExistingPeriodicWorkPolicy.UPDATE for more details.

API Changes

• WorkManager.updateWork was added to update work preserving its original enqueue time and chaining.(I9a248, b/219446409)
• ExistingPeriodicWorkPolicy.UPDATE was added. This policy allows updating a periodic work by the name. It is similar to the existing REPLACE, but it is less intrusive: it doesn't cancel a worker if it is currently running and it preserves enqueue time - initial delay and period are calculated from original enqueue time, rather than update time. REPLACE was deprecated to decrease a confusion between the very similarly named REPLACE and UPDATE. If you still want to keep the previous semantics of REPLACE, the newly added CANCEL_AND_REENQUEUE, which is identical to REPLACE, can be used. (I985ed, b/219446409)
• Added the ability to intercept scheduling exceptions providing Consumer<Throwable> via setSchedulingExceptionHandler)
• Added the ability to provide Consumer<Throwable> via setInitializationExceptionHandler to determine if there were issues when trying to initialize WorkManager.
• Inline helpers for OneTimeWorkRequest & PeriodicWorkRequest were moved from androidx.work:work-runtime-ktx to androidx.work:work-runtime (I0010f, b/209145335)
• Helper methods WorkQuery.fromIds, WorkQuery.fromStates, WorkQuery.fromUniqueWorkNames, WorkQuery.fromTags were added to create WorkQuery directly. (b/199919736) (If48f2, b/199919736)
• Added getForegroundInfo to Worker. (Ic1ead)
• RxWorker both for RxJava 2 and RxJava 3 now has setForeground returning Completable that can be used instead of setForegroundInfoAsync that returns ListenableFuture
• RxWorker both for RxJava 2 and RxJava 3 has getForegroundInfo returning Single that can be used instead of getForegroundInfoAsync that returns ListenableFuture. (b/203851459)
• Constraints can now be directly constructed rather than using Constraints.Builder, which is convenient for Kotlin users. (Idc390, b/137568653)
• Added the ability to check if WorkManager has been initialized. Also, added a new getConfiguration() API for library developers to get the configuration that WorkManager was initialized with. (I6eff3, b/212300336)

Bug Fixes

• Fixed an issue with the greedy scheduler that would prevent workers from running immediately when under load. (I9686b, b/248111307)
• Added @RequiresPermission to APIs that require granting the POST_NOTIFICATIONS permission on SDK 33 and above. (Ie542e, b/238790278)
• Propagate cancellations in the CoroutineScope to the ListenableFuture when using suspendCancellableCoroutine.
