There can different cases at what time activity get destroyed.įirst is if user pressed the back navigation button then activity will be destroyed after completing the lifecycle of pause and stop. It gets called only in case when activity is resumes after stopped state.Īny activity is known as in destroyed state when it’s not in background. In other words, when Operating System starts the activity for the first time onRestart() never gets called. So activity’s onRestart() function gets called when user comes on screen or resume the activity which was stopped. In this case application will not present anything useful to the user directly as it’s going to stop.Īctivity is called in restart state after stop state. So Activity will be in stopped state when hidden or replaced by other activities that have been launched or switched by user. In this case Activity displaying content for screen 1 will be stopped.Įvery activity gets stopped before destroy in case of when user press back navigation button. For example, if a user was on screen 1 and click on some button and moves to screen 2. Any activity gets stopped in case some other activity takes place of it. For example, if a call or notification comes in, the user will get the opportunity to take the call or ignore it.Īctivity is called stopped when it’s not visible to user. Similarly, if the other screen or dialog is transparent then user can see the screen but cannot interact with it. The activity will go in paused state for these reasons also if a notification or some other dialog is overlaying any part (top or bottom) of the activity (screen). In lifecycle it always gets called after activity start and in most use case after activity paused ( onPause).Īctivity is called paused when it’s content is not visible to user, in most case onPause() method called by Android OS when user press Home button (Center Button on Device) to make hide.Īctivity also gets paused before stop called in case user press the back navigation button. And again if a user again click on app icon of Application A then Application A which was stopped will again gets started.Īctivity resumed is that situation when it is actually visible to user means the data displayed in the activity is visible to user. For example, if a user was using Application A and then a notification comes and user clicked on notification and moved to Application B, in this case Application A will be paused. So this means onStart() gets called by Android OS when user switch between applications. In other case Activity can also be started by calling restart method i.e after activity stop. OnStart() method is called just after it’s creation. Learn More About onCreate(Bundle savedInstanceState) With Example
