![]() There's no word yet on what's included in the iOS 12.5.5 update, but according to Apple's release notes, it is a security update that addresses vulnerabilities with CoreGraphics, WebKit, and XNU. The update can be downloaded over-the-air by going to the Settings app, tapping on "General," and selecting the "Software Update" option. If C has set the "I'm Destroying" flag, then don't perform the request.Apple today released an iOS 12.5.5 update for older iPhones and iPads that are not able to run the current version of iOS, iOS 15. Have C pass some flag up to the controlling activity (we'll call it Main), move the async call up, and when B wants to do the web request, have it call up to main to do so. ![]() If this is null you could then assume that the operation in action is the destruction. When onResume is called you could do a getFragmentByTag on the fragment which has already been destroyed. Have you determined what other lifecycle methods are being called - if it's only on resume, then move the async call further down in the lifecyle (onCreateView or onAttach for example) so that it's only called when moving through it in the normal manner. Note: I'm using the latest compatibility/support library. In this case how can I detect if the entire backstack is being collapsed and skip the async web request on Fragment B in the OnResume method? Note: I'd still want the async web request to execute if Fragment B is popped/displayed by using the Back button. For Fragment B, I don't want the async web request to trigger since its going to be immediately destroyed/removed after its popped (because the entire backstack is being cleared). As each fragment is popped the fragment's onResume method is called. ![]() When PopBackStackImmediate is called it pops the Fragments off one by one until the stack is cleared. Fragment B tries to make a async web request when its onResume is method is called.įragment C has a button called "Clear Backstack" that clears the backstack by calling popBackStackImmediate(null, FragmentManager.POP_BACK_STACK_INCLUSIVE). ![]()
