This is exactly what I have been looking for... an exact breakdown of Android Studio/ Kotlin process. Thanks for taking the time to making this!

@viz_dugz Год назад

Super excited for this playlist. As someone who just started Android development, it is super important to know about concepts like Intents, Services, etc. You putting this content out there means a lot.

@xCrawfly Год назад

Hi Philipp. This is very well described and simplified for an easy overview-understanding. Thank you for this new playlist, I'll be waiting for the next videos!

@Ayor88 5 месяцев назад

intersting video but to be honest, this informations a pretty clear on the official documentation. What would have been really great is example of what typical actions would be done in each function. Maybe with an example app (like a store, a messaging app or anything usually used for educational purpose)

Hyped for this series too. I have an app in the Play Store but its very basic and my understanding of the Android fundamentals is lacking. A series like this will hopefully fill in the gaps.

@Nostang3 Год назад

I would love a video on when to use each state or best practices for them.

@chisomemmanuel6160 Год назад

Yeah i love ❤ your videos and liked the way you made emphasis on 11:56 because I've been in such weird situations whereby Android's operating system can decide to destroy your activity without calling on destroy() method and it made me debug almost all day.. Now, you've talked about saving states mostly in onPause but imagine destroying Viewpager2 and it's adapter in onPause method 😢and recreating it in onResume. I had to make use of Viewmodel to store the created adapter and call it from activity after creating it's object via local variable but it shows with tablayout once and never show again without exception in logcat which is very weird.

I have fetched some data from db or api and it is stored in view model. Example, in login screen i have fetched user data and stored in loginViewModel. when i move to next screen after login screen. When i try to fetch data from loginviewmodel in next screen it is showing null.

Hi, Phillips @Phillips I have learnt a compose from your tutorial. I have a question or I need some suggestions from you. If I want to move from compose to flutter. Is it better to choose flutter instead of compose. I am so confused about choosing one. I shall be waiting for your reply. Thanks in advance

@asadullahilyas Год назад

Hey Philipp! Are you sure activity is paused if a dialog is shown? Because as far as I know, if your activity is opening a dialog, then it doesn't pause that activity. Although, when permission request dialogs are shown, they do pause our activity, but that's because those dialogs are opened by Android SDK in another (transparent) activity, since every dialog needs an activity to get displayed. So, our activity is paused because, again, another activity is now on top.

@PhilippLackner Год назад

Yes sorry I was referring to the permission dialogs

@zteve_music 6 месяцев назад

Is there also something like an application lifecycle or is there only "App is started/created" and then sometimes destroyed?

@TheBlackManMythLegend Год назад

5yr android developer my advice to guys doing that READ THE DOCUMENTATION GUYS and work in professional companies to ingrain the concepts ( like ci/cd units tests. and all theory necessary like activity and stuff. And ... RTFM but it's also good to have the feedback from other guys like PLack. of course but don't forget to go to the source yourself.

@slayerofall149 Год назад

i would like to learn Android development, should is jetpack compose and these videos the same? Sorry for the question, but it's a little bit confusing, a lot of tools around android

@brianquigley1940 2 месяца назад

Configuration change (rotating screen) "destroys" the app, so it "recreates" the app... thus, the official Google diagram is incomplete... where's the arrow pointing back up to onCreate? Isn't this where "bundle" is passed with the old "state" of the app? (before the config change)

@PhilippLackner 2 месяца назад

The app isn't recreated, just the activity. The process remains. The activity can be destroyed for many reasons, and then the graph starts at the start again which is probably why they've left it out

@brianquigley1940 2 месяца назад

@@PhilippLackner Thanks for responding. I meant activity. (Still getting used to the concepts.) So, in essence I was right, except that the arrow should go from Activity Shutdown back up to Activity Launched for every configuration change (e.g. screen rotation). What threw me completely when I first encountered the Activity lifecycle was "Activity Running". What was it doing? This may seem obvious to experts, but it took me ages to realize that "Running" actually meant "a wait loop checking for something to happen" (i.e. event "listening"). All else follows... namely, all code serves to respond to an event, usually user input (or some other event like a notification from an external service). In any case, thanks for the videos. The more I watch, the more I understand. 🙂👍

You missed screen rotation which would also call onDestroy(). Also configuration changes.

@@PhilippLacknerI already completed half of the Android fundamentals for beginners 2020 but I will take this course from now onwards. Thanks 👍

@jackcsk Год назад

When you override onPause() and onStop(), it’s better to leave the super class function (super.onPause()) as the last line instead of first. That’s because you have to ensure your child activity/fragment handling is done, and the onPause() / onStop() from super class is not causing any unexpected effect on your child dependent usages (e.g. a referencing variable became nullified)

@gower1973 Год назад

Hey Phillip I just started with Android development, but I’m finding that projects seem to be taking up hundreds of MB of disk space even when the project itself only takes a few MB on disk, why am I losing so much disk space? I swapped out the emulator to one that used much less space but it makes no difference, I don’t understand why Android dev uses so much resources for very little development.
