com IPTV and it features an attractive tutorial we also have sample applications which you can see on monitor that i've developed which have been created with compost it gives you an concept of the aid We've got a cloth design and style and compose marks Yet another drastic g-drive it truly is developed solely during the open although work comes about in USP along with the crew engages in every day discussions Using the Neighborhood had been current on the slicing length slack channel you can sign up for us If you prefer and we also operate month to month the developer research and due to all of the opinions that we are obtaining consistently we've now designed several lots of API improvements I would like to thank all of you who are aiding us and supporting us you recognize factors are only recovering as a result of you and because of that feedback our existing system would be to ship that back again on publish as a much better next yr as you just observed inside the demo when it works compost will work is made in shut connection with Android Co but I will Allow Karen inform you more details on the IDE I am Individually seriously excited about compose but certainly one of my favorite points about compose is that there is entire Android studio assistance Android studio could be the Formal IDE for Android and we've come to date given that our wono release it has comprehensive assist for Windows Mac Linux and in addition Chrome OS with Professional OS application utilization rising four occasions in the final year Therefore the workforce continues to be focusing on far more than simply compose And that i choose to explain to you a few of that so we have been 1 we need to make iterating and code speedier doing things such as the preview or the embedded emulator executing such things as use changes making more rapidly deployment sees speeds or even exhibiting a preview of Chromebooks in which you can deploy your application directly on to a Chromebook which means you take a look at and produce on exactly the same precise equipment we are also thinking about present ache details and we have listened to that animation is severe we have heard that looking at methods is tough so I am gonna pass it back again to Ramon to demonstrate a little bit more about some non compos stuff all right simply because before I get to your enjoyment bits I just choose to tell you about a great off script published in Catalan and naturally you have got usage of the total electric power from the Strategies We've got a great completion go ahead code completion you are able to do it and you've got rapid fixes all ideal so Here is the Visible editor using constraint structure if I click on the widget for anyone who is informed about construct layout you are aware of This really is what you're Whatever you're That which you expect and We now have this panel that we wish to open up from the bottom and we want to animate that and you simply all know that sometimes performing animations on Android may be actual tough first You need to select which API to work with so we determined to really make it less difficult within the tools so Should you have a constraint out you could good click on it you could click on change to motion layout we settle for and now you may see that we have a begin and conclusion state and from here what you'd probably do is you'd probably change the posture of the widgets in different states you may build your own personal States and from you can make an amid transition so I'm going to swap to a special files We've got finished you already know the vast majority of work to help you see my begin condition in which everything is collapsed you can see my finish point out exactly where anything is open up however , you can animate far more than simply constraints in the event you consider the colour on the advert bar within the fab it is possible to see which the change involving The 2 dates and now if I choose this transition arrow I'm able to Enjoy the admission appropriate right here in di DT and I can't even scrub back and forth so it makes producing admissions a lot less complicated so Yet another point I would like to provide you with is right here so I'll run this app the application alone is not Tremendous interesting what is appealing Is that this new Dwell layout inspector at the bottom so you merely related and you may see that After i Enjoy with the application if I change the display the inspector updates in authentic time and naturally now It really is tagged okay in this article we go I am able to choose any from the sights and it will find them in the the Harkey within the still left you can inspect all of the characteristics if I choose the submit button it does something that I discover great consider the text size it suggests fifty and we all know that themes and models by now or complex and at times It truly is not easy to know in which the value arises from Therefore if I extend this it is going to tell me it originates from these fragments and it came from that dimension benefit and you can see that we're overriding the original worth of 18 that's defined within the fashion and the identical so you won't have to spend several hours any more debugging systems and styles prior to we go back to Kent can you switch to the other demo make a difference since I mounted them [Applause] many thanks Ron which was terrific so it is the equally as we mentioned seamless compatibility with compose and how you can expect to convey it along with your current code exactly the same applications crew is working on both equally so lots of That which you observed here is gonna work from the composer globe so we understand that the IDE even though is in which you expend all your time so if the IDE is hanging or your builds take much too prolonged it won't issue how interesting the attribute is and we listened to you loud and crystal clear make our IDE rock-sound we devote eight months on task marble focused on steadiness overall performance and fundamentals for Android studio 35 we observed double-digit improvements sixty% drop in UI hangs our freeze occasions 40 % fall in UI hangs more than 50 memory leaks preset 23 p.c fall in Gradle sync failures along with a fifty seven p.c faster deployment speeds we took some time for getting some functions so we didn't get proper the first time like fast run we rebuilt them entirely from the ground up we relaunched them as apply adjustments and then we deleted in excess of 50, 000 traces of code and we recognize that we are not accomplished however we are dedicated to a deal with good quality and we built the infrastructure along with the dashboards that we needed to retain finding this suitable Okay let us mention Establish velocity it's been the number one regret requests for the last 5 decades we saved chipping absent at Establish speeds our Gradle Create speeds but complete Develop times were not acquiring more quickly code bases ended up receiving greater custom made plugins we're adding to build situations incremental process annotation processors we are negating the benefit of incremental Establish so we broadened our concentration and we tackled the highest annotation processors glide databinding dagger They are all incremental now and we did not prevent there resource processing multi module dexing making only a single art course they're all more rapidly and those ordinary Establish occasions we're looking at 24% drop and they're enhancing each and every release And eventually we're encouraging you see difficulties in your own personal builds by aiding you visualize what's time invested through the Establish pipeline so you can see if it is a custom made plugin if It really is Make configuration and then pick what to do with all your personal builds Alright ok just moments ago we produced the primary canary of Android studio for oh it consists of it includes the preview of our contou swing you noticed with Ramon in order that Dwell preview the code completion a full sample and it has the challenge templates It can be way easier to Check out compose it's got Java 8 library G sugaring it's got the movement editor has total aid for kts documents and get in touch with them Are living templates and now I would like to ask Tien to tell us more details on modern distribution [Songs] [Applause] [Tunes] [Applause] [Songs] Hello everyone I'm 10 And that i operate products and UX for Google Play and Android app basic safety currently practically marks my second anniversary of Google in that quick time I've achieved quite a few gifted and creative developers throughout the world and it has been Specially inspiring for me Once i pay a visit to marketplaces like Brazil or Nigeria and meet up with builders who've been capable to make international audiences or Develop organizations that solve real community troubles as you read Dave stated earlier person privacy is foundational to what we do if customers You should not rely on Android and Enjoy and there won't be everyone to download your apps have confidence in and safety has usually been a prime priority at Engage in with human reviewers regular improvements to play shield and policy updates to evolve Together with the threats that we see Because of this apps which can be downloaded from Perform are an get of magnitude safer than from every other source this yr we have been raising all our detection capabilities for impersonators repackaging poor content and also other kinds of abuse but We all know there is a large amount far more that we could be doing we have seen SDKs that appear nicely behaved but later try and do nasty things such as enlist a person phoned right into a botnet or exfiltrate personalized data we are up against some seriously subtle undesirable actors but I am also pretty happy with the best way that we have taken action using your support we have lowered use of sensitive info and should Perform even safer for kids and People we restricted SMS and phone our permissions to only applications that require them as part of their core operation Due to this fact ninety-8 percent much less apps now obtain the delicate knowledge This is often owing to your effort buyers at the moment are safer and they know They are safer once they obtain apps that request less permissions now to aid shield children and to provide mom and dad more self esteem when choosing apps for their young children we up-to-date our households procedures then much more stringent with regards to content material advertisements and PII and we are inquiring you To learn more on who your application is for thus we are able to superior surface area the appropriate content material to the proper age groups we're not halting there we are dealing with academics to higher recognize high-quality applications for youngsters we're working on regulations to make sure end users realize their subscriptions we're Functioning to ensure developers accessibility qualifications site info correctly and we are engaged on improved defending your intellectual property we are also beginning to work with SDK providers that can help them increase their excellent and enable app builders know which SDKs are Protected just to provide you with an notion of the size at which We've to work we lately took motion towards a malicious SDK it impacted 200, 000 apps as you may think about It can be sort of difficult to reliably arrive at out to two hundred, 000 developers now let me pause there And exactly how which is plenty of transform and improvements like they are seriously not easy to make gracefully on this sort of a considerable ecosystem we have an understanding of the burden that it sites on you to possess to constantly adapt to new insurance policies particularly when the overwhelming majority of you may have done nothing wrong you've got instructed us that our modify procedure could use some perform that our communications are much too vague impersonal or that You may have wanted far more time that is absolutely on us to repair And that i assure that we will continuously enhance During this area now I get plenty of questions on application critiques and developer Bands I need to provide you with a sneak peek powering the curtain on a daily basis We've got individuals examining thirty, 000 new and up to date app submissions While a lot of the additional complicated evaluations may well acquire approximately 7 days most apps are reviewed inside of a pair and as constantly all appeals are reviewed by humans now builders that regularly crack plan are banned from Participate in these builders use several strategies to acquire new accounts and check out and check out again methods are seriously fantastic below the overwhelming majority of accounts are banned the right way and plenty of are bent ahead of the bad actor has a chance to publish occasionally we get it Erroneous though and we understand that Those people exceptional situations are Tremendous distressing any developer lender is often appealed It's going to be reviewed by our worldwide team and if a mistake is identified they are going to be reinstated we'll keep on to enhance in this article we are also Performing to incorporate extra useful detail while in the play console with information on the position of app opinions coverage variations That may affect your applications and various significant facts so seek out some massive modifications in the approaching yr We have now to help keep our people Protected It can be within our shared curiosity It can be the sole way We'll preserve this System escalating and flourishing so make sure you keep dealing with us remember to keep delivering opinions and support us by means of this period of improve now let's speak about many of the strategies we're assisting you get to users and Create your companies it's been eighteen months due to the fact we launched the Android app bundle as our eyesight for the way forward for app distribution around a quarter million at bundles at the moment are in generation covering twenty five% of all Energetic installs builders at switch see pretty sizeable decreases in application dimension and as a result some have noticed an around eleven% uplift in installs based on your responses we're making application bundles and dynamic supply a lot easier to test internal application sharing lets you test builds within your application bundle as easily while you share apks what is great is that you could grant anybody with your team access to artifacts without offering them console accessibility we're also making it probable to Det to to get obtain inbound links for previous versions of your application whether or not they were being bundles or apks ultimately lots of you are asking for this we're launching offline testing of dynamic shipping and delivery nowadays with the fake break up install supervisor yet another way that we assistance developers is by assisting them start productively from beta testing functions to specialized good quality tests to staged rollouts We now have numerous options to assist you acquire your plan to sector recently we have been centered on creating demand pre-reg is actually a best practice for building enjoyment around your app or sport we launched two typical availability at GDC and lots of builders are using this to terrific achievement according to your responses we've been adding capabilities to the program several illustrations next on a Korean dev use pre-reg benefits to supply customers three hundred diamonds for pre-registering the players who pre-registered had Just about fifty% increased days sixty retention and 70% larger our tau editor max a brazilian dev ran a pre reg campaign with milestone rewards with four milestone ranges Each and every unlocking a novel in-activity product and end users who pre-registered Enjoy thirty% far more each day minutes we also just finished An additional thriving launch just a little Thailand you will have heard Connect with of Obligation mobile that observed almost sixty million installs in the primary 10 days with our new retail store goods and abilities we have been equipped to construct hype everywhere in the planet and push tens of many pre-registrations we actually also worked right with them to enable custom made beta teams so they may test their activity on precise units in particular locales this distinctive beta system is a thing we hope to scale out to extra developers actual soon A different long-expression guess for us is Enjoy pass at $four.
