Android Runtime - How Dalvik and ART work?

[@BuffaloCanCode]

In the last 11 years of my Android journey, this is the first time when I felt few basic things are still missing from my knowledge. Thank you Paulina for covering "Profiles in the Cloud". I completely missed this thing before. Great content and keep posting small videos... Happy Green Robots :)

[@akhileshramteke6290]

In recently, I attended interview there They have ask ART. From that day onwards I am searching the proper guidance of ART. From your video now I can say how ART works. Thanks for creating such wonderful tutorial. Its really helpful.

[@Dipak2323]

Wow! I knew about Dalvik and ART switch but never knew about hybrid and profiles in the cloud approach! This was really informative. Thanks 😃

[@clewfirstcfer]

You are explaining clearly and succinctly with minimal preamble. This is better than the majority of Android videos out there. Keep going.

[@lumina3914]

finally i understand why my phone become slower and slower when i turn on the android phone. your explanation is so clear. thanks.

[@yousefkazemi785]

Every android developer should know this. thank you Paulina for posting content and videos like this.

[@mamathak.p8609]

Before a while seeing this video my mind is blank about ART,DALVIK,JIT and AOT. Now i am clear about all this. thank you Paulina for this precise presentation. ☺

[@NishantRathoreXYZ]

And I'm beginning in this field because I'm inspired from you. Thanks for inspiring me ❤

[@pqsk]

I remember when art was announced and you had to toggle it manually on the Android system settings. I never knew all of these details, just some of it. Great video

[@binarytv2904]

Fantastic explanation. After browsing thorugh endless sites I still couldn't understand the what was really going on under the hood. Its very clear now. Thanks Paulina.

[@U4Universe]

You've explained the topic in a very easy & understandable way. Very easy to understand. Thanks. Really forward to new videos from you. Btw how did you make these amazing slides??

[@jonathanesquivelmartinez3455]

You explain very well. Congratulation!! you know how to do it! You have a new fan! I loved it!

[@GirishGoradiya]

i love this video, I am Fresher in Android Development So thank you For this video 😍😍😍😍

[@keyboardsurfer]

Awesome historical overview of how Dalvik and ART make things faster. I'd love to see your take on Baseline Profiles as wel.

[@samshekhawat]

most educating video for android runtime process, thank you!! make more video like this

[@mingato5538]

Please make video about memory leaks, garbage collectors and weak,strong reference. Good job ♥️

[@akhileshramteke6290]

Yes please cover above topics.

[@marcinlaskowski4449]

Great video! 😁 One thing: KitKat had both Dalvik and ART, only the second was disabled by default. However, it could be turned on from developer settings. Feeling old now, because this change happened when I was starting my dev career 😃

You got me, I omitted this part to not make video too long :D

Noticed this channel recently. Love the explanation. Could you please create more of such videos.

[@codyrap95]

Insanely useful video, thank you! The explanation is very valuable and the graphics+image quality are on point, but If you want a tip, try to improve your English a bit, would raise the production quality substantially. Thanks again

[@kannans6462]

Great, informative and to the point. Thanks!!

[@nghiaminh7704]

Hi. Correct me if I'm wrong: 1. JIT was introduced with Froyo (2.2), before that Dalvik was like a pure interpreter. 2. I think the profile-guided compilation part just explains what JIT is, nothing more. Google is to blame for introducing fancy words instead of saying "we bring JIT to ART".

[@zer0gaming1991]

Oh my god an angel 😍

[@panjak323]

How does running JIT, AOT and caching everything, along with app packages being a magnitude larger than anywhere elese result in smaller RAM usage ? Android is pretty notorious for abusing memory, typically 3x as much as iOS for the same apps.

[@Abelmengesha-sp6lv]

I love it

[@LiranBarsisa]

Interesting video. What about memory though? I've noticed that starting from some Android version, Bitmaps got to be stored on the global RAM and not as a part of the heap, meaning that apps won't reach OOM exception so easily by Bitmaps. In fact, when I tried to fill the memory with bitmaps, I got weird, other issues that sometimes can't be detected or be caught by the app (using try-catch). Not only that, but in the past I remember we could take a memory report (dump) and see the content of the bitmaps, but now It's impossible. Is this all true?

[@PaulinatalksAndroid]

Hi! When it comes to seeing then content of the bitmap in memory dump, you're right it's not possible from Android 8. I happen to mention that in one of my previous videos kzbin.info/www/bejne/bmO7hpiqpMeJibc :) But I don't think it's connected to changes in ART, AFAIK there were some changes in bitmap implementation that caused that. And about the memory: there were the changes in how memory is managed in different Android versions but I don't know if (and how) it influences the case with bitmaps that you described. I think it only influences the garbage collection. There is a great talk from Google I/O where they describe those changes, maybe this will be helpful? kzbin.info/www/bejne/Z6avq4aOjLyZesk

[@LiranBarsisa]

@@PaulinatalksAndroid Are there any plans to handle bitmaps nicer? While it's much harder now to fill the memory with bitmaps and cause issues from it, it's still theoretically possible. Would it be possible to get their content? To use try-catch when creating them (avoiding possible crashes) ? BTW, I know about the GC. I even remember when bitmaps became a part of the heap properly (was on Android 3.0 as I remember).
