Whether your pastime has stopped being noticeable to the consumer, this has entered the new Eliminated condition, therefore the system invokes the brand new onStop() callback. The device may name onStop() if the passion provides done powering, and that’s going to getting ended.
In the event the pastime movements toward eliminated state, any lifecycle-alert component tied to the newest activity’s lifecycle are certain to get the newest Into the_Avoid experiences. This is how the latest lifecycle components can also be avoid one features one does not need to work at because component isn’t noticeable to your monitor.
On onStop() strategy, the fresh application should discharge otherwise to alter information that are not called for since Web baДџlantД±sД± software is not visually noticeable to an individual. Particularly, your own software you’ll stop animations or button regarding okay-grained to coarse-grained venue status. Using onStop() in lieu of onPause() means UI-related really works continues on, even if the member was watching the pastime within the multiple-screen means.
You should also fool around with onStop() to do seemingly Central processing unit-rigorous shutdown procedures. For example, if you can’t see a far more opportune time for you to save yourself guidance so you can a database, you could potentially do it through the onStop() . The second example shows an implementation of onStop() you to saves the fresh new items in an effective draft notice so you can chronic shop:

When your activity goes into new Stopped county, the activity object are kept resident when you look at the memories: It preserves most of the condition and user pointers, but is maybe not connected to the windows director. If interest resumes, the game recalls this article. You don’t have to re also-initialize parts which were composed during any of the callback steps prior to new Started again county. The computer and tracks the present day state per See target in the style, anytime the user inserted text into the an enthusiastic EditText widget, one articles is retained which means you won’t need to save yourself and you will heal they.
Note: When your craft try averted, the machine you’ll destroy the process that has the experience when the the machine should get well memory. Even if the program destroys the method as the craft is averted, the device however retains the condition of the view items (such text into the an EditText widget) for the a bundle (good blob out-of trick-worthy of pairs) and restores her or him in the event your user navigates back into the game.

Regarding Avoided county, the experience possibly return to activate to the affiliate, or even the pastime is fully gone running and you will goes away. When your interest return, the device invokes onRestart() . If the Passion is finished powering, the system calls onDestroy() . Next section explains the onDestroy() callback.
onDestroy()
- the activity is completing (as a result of the member completely dismissing the experience or due to finish() being titled towards interest), or
- the device was temporarily destroying the activity because of a configuration transform (particularly equipment rotation otherwise multiple-window means)
If passion moves toward shed state, people lifecycle-alert component tied to this new activity’s lifecycle will have the brand new To the_Destroy skills. That’s where this new lifecycle parts normally tidy up some thing it should up until the Hobby are missing.

When your Passion would be reproduced because of a great setting alter the ViewModel shouldn’t have to do anything once the it could be preserved and you will given to next Activity such as for instance. In case your Pastime won’t end up being reproduced then the ViewModel will get new onCleared() method named in which it does clean up any study it needs so you’re able to in advance of are missing.
