The crucial ingredient DevFeed: [The legend about AIDL. Part 3. The crucial ingredient]() Original publisher: [Read original article]() Author: Vladislav Puryev Published: 2021-01-16T14:50:56Z Content type: tutorial Language: en Sources: [Stories by Vladislav Puryev on Medium]() Topics: [Android](), [Code]() Tags: [android](), [aosp](), [code](), [code-search](), [ide]() ### AI overview This third installment of a series examines how Android Interface Definition Language (AIDL) is used within Android system code. It traces calls involved in launching an Activity and follows the handling of Bundle and ActivityOptions objects, using shortened code examples from Android 10 sources. ### Source excerpt Hello everybody. In the previous two parts you could read a lot of things about Android Interface Definition Language. About its origin, theoretical and practical basics, how these basics are implemented in Android system, how AIDL works and how developer can use it (as a result, quite simple) and some other things about Android and computer science. Well now, everything of this is pretty curious, but I would like to tell you about one more interesting thing. You are using AIDL much more, than you suppose. WARNING! This article contains a lot of code that will be provided in shortened form. Full versions you can find in your IDE, in AOSP or Android Code Search. Please be careful, cause most of further code can be changed any time by Google developers, that is why some material can be obsolete and partially or completely wrong in the future, but actual for the moment of publication. All code is retrieved from sources, which actual for Android 10. This series of articles consist of three parts: The legend about AIDL. Part 1. The roots The legend about AIDL. Part 2. In Action The legend about AIDL. Part 3. The crucial ingredient (you are here) The biggest one The statement above is quite brave, isn't it? Let's research the code and see that AIDL is more important, than any Android application component. The first opponent is Activity. Bigger, than Activity This is ridiculous, isn't it? How much times developers (and their users) are using Activity and how much times they need AIDL? It seems that crushing blow is directed to the hero of article. To prove this incredible fact it needs to look at the content of method, which allow to launch activity -- startActivity(). https://medium.com/media/0b4ea8396635cc920b6335a25c0aef13/href This method is calling another one startActivity(), passing null for parameter options. Depending on this value, second startActivity() calls startActivityForResult() with options or not. Let's dig deeper. https://medium.com/media/9855de0e0c3444e ## Jetpack Compose - now on Maven DevFeed: [Jetpack Compose - now on Maven]() Original publisher: [Read original article]() Published: 2019-10-14T07:56:37Z Content type: tutorial Language: en Sources: [Posts on Adam Bennett]() Topics: [Jetpack Compose](), [Maven](), [Android](), [aosp]() Tags: [algorithms](), [android](), [aosp](), [blog](), [career](), [compose](), [demo](), [development](), [engineering](), [finance](), [functional](), [growth](), [java](), [jetpack](), [jetpack-compose](), [kotlin](), [maven](), [money](), [opinions](), [software](), [startups](), [thoughts](), [training](), [tutorial]() ### AI overview A historical demo shows how Jetpack Compose libraries could be fetched from Google's Maven repository and used in an Android app. The author notes that the approach is deprecated and that the example compiles but has subtle runtime and behavioral problems. ### Source excerpt This article is also now deprecated, but I'm keeping it up for posterity. This article was a quick demo and explore of the Jetpack Compose library, with the binaries being fetched from the then-newly discovered Maven links. Whilst it technically compiles and renders the Views, it's broken in subtle ways (such as observing @Models, which is half the point of Compose). ## Mobile Platform Convergence - Kevin Galligan DevFeed: [Mobile Platform Convergence - Kevin Galligan]() Original publisher: [Read original article]() Published: 2018-04-04T16:07:02Z Content type: opinion Language: en Sources: [Touchlab | Enterprise Mobile Innovation & Development]() Topics: [Mobile](), [Android](), [iOS](), [aosp](), [SQLite](), [Java]() Tags: [android](), [aosp](), [code-sharing](), [featured](), [ios](), [java](), [kotlin-multiplatform](), [mobile](), [platform](), [sqlite](), [thoughts]() ### AI overview The article argues that Android and iOS differ substantially in implementation but share similar architectural foundations, including Unix-like systems, files, threads, networking, and SQLite.
