No. Your entire application can be killed and recreated with the task stack intact; this lets the system reclaim memory on devices that need it while still presenting a seamless illusion of multitasking to the end user. From the docs: A background activity (an activity that is not visible to the user and has been … Read more
See also This post on Cocoanetics that present a very useful flowchart explaining the different calls to the AppDelegate methods during the app life cycle:
onPause() is called when your activity is no longer at the top of the activity stack. A Dialog by itself is not an Activity, so will not replace the current Activity at the top of the stack, so will not cause anything to pause. A dialog (lower-case) does not need to be implemented by a … Read more
<div (window:beforeunload)=”doSomething()”></div> or @Component({ selector: ‘xxx’, host: {‘window:beforeunload’:’doSomething’} .. )} or @Component({ selector: ‘xxx’, .. )} class MyComponent { @HostListener(‘window:beforeunload’) doSomething() { } } This is how to listen to global events. I don’t know if the special behavior of this event is supported where the return value is used as text for the conformation … Read more
Removing definition does both : removing definition and destroying (removing all container references on that bean) corresponding Singleton : ((BeanDefinitionRegistry) beanFactory).removeBeanDefinition(“myBean”); If you just need to remove the singleton then : ((DefaultListableBeanFactory) beanFactory).destroySingleton(“myBean”); The latter way may be especially useful if you just registered singleton but haven’t defined any bean definitions, i.e. ((SingletonBeanRegistry) beanFactory).registerSingleton(“myBean”, myBeanInstance);
I’m going to post the comment of @H9kDroid as the best answer here for people that have a similar question. You can use isTaskRoot() to know whether the activity is the root of a task. I hope this helps
The view build time is not a phase. The view build time is that moment when the physical UIViewRoot instance and all of its children is built based on the view declaration, which is usally defined in XHTML or JSP files. The view build time moment is not restricted to a specific JSF lifecycle phase. … Read more
I believe the OP is long gone, but in case this answer is able to help future searchers, I thought I’d post a solution that I have found. I have added this code into my onCreate() method: EDITED: 07/05/11 to include code from comments: final TextView tv = (TextView)findViewById(R.id.image_test); ViewTreeObserver vto = tv.getViewTreeObserver(); vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() … Read more
I still don’t understand why inactive activities that are on the stack don’t get reaped, and I’d really love to figure that out. This is not how things work. The only memory management that impacts activity lifecycle is the global memory across all processes, as Android decides that it is running low on memory and … Read more
All these commands are called automatically at the appropriate times by iOS when you load/present/hide the view controller. It’s important to note that these methods are attached to UIViewController and not to UIViews themselves. You won’t get any of these features just using a UIView. There’s great documentation on Apple’s site here. Putting in simply … Read more
