Create new app with root frame\r\n2. From default page navigate to a second page via button tap like this:\r\n``` ts\r\nexport function onTap(args) {\r\n    const navigationEntry = {\r\n        moduleName: \"home/second-page\",\r\n        animated: true,\r\n        transition: {\r\n            name: \"slide\",\r\n            duration: 5000,\r\n            curve: \"easeIn\"\r\n        }\r\n    };\r\n\r\n    args.object.page.frame.navigate(navigationEntry);\r\n}\r\n```\r\n3. Suspend the app\r\n4. Resume the app quickly (within 5 seconds so the \"exit\" transition is still playing) -- the \"exit\" slide animation is ongoing and crashes the app mid-way with the following exception:\r\n```\r\nAn uncaught Exception occurred on \"main\" thread.\r\nandroid.content.res.Resources$NotFoundException: Unable to find resource ID #0xfffffff6\r\n\tat android.content.res.ResourcesImpl.getResourceTypeName(ResourcesImpl.java:271)\r\n\tat android.content.res.Resources.getResourceTypeName(Resources.java:1986)\r\n\tat android.support.v4.app.FragmentManagerImpl.loadAnimation(FragmentManager.java:1172)\r\n\tat android.support.v4.app.FragmentManagerImpl.moveFragmentToExpectedState(FragmentManager.java:1808)\r\n\tat android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1852)\r\n\tat android.support.v4.app.BackStackRecord.executeOps(BackStackRecord.java:802)\r\n\tat android.support.v4.app.FragmentManagerImpl.executeOps(FragmentManager.java:2625)\r\n\tat android.support.v4.app.FragmentManagerImpl.executeOpsTogether(FragmentManager.java:2411)\r\n\tat android.support.v4.app.FragmentManagerImpl.removeRedundantOperationsAndExecute(FragmentManager.java:2366)\r\n\tat android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:2273)\r\n\tat android.support.v4.app.FragmentManagerImpl$1.run(FragmentManager.java:733)\r\n\tat android.os.Handler.handleCallback(Handler.java:873)\r\n\tat android.os.Handler.dispatchMessage(Handler.java:99)\r\n\tat android.os.Looper.loop(Looper.java:193)\r\n\tat android.app.ActivityThread.main(ActivityThread.java:6669)\r\n\tat java.lang.reflect.Method.invoke(Native Method)\r\n\tat com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)\r\n\tat com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)\r\n```\r\n\r\nMost probably we should cancel/clear the animator if we detect app is going to suspend as we should not be seeing the \"exit\" transition on app resume.","author":{"url":"https://github.com/manoldonev","@type":"Person","name":"manoldonev"},"datePublished":"2018-11-05T15:13:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/6510/NativeScript/issues/6510"}
