  1. Hi madam. I have an issues about databinding. Even i enable in gdle but still show error. Even i try to import such that androidx. databinding. DataBindingUtil nothing working. Please make tutorial how to fix it that error thank You

  2. 1:05 Why should we use another immutable variable to expose? Why not use the mutable live data to observe?

  3. A lot of good things about live data, but it's actually very bad.

    – No normal error handling

    — If 'observe' is not used in the 'onCreate' method, then there will be problems when change screen orientation

  4. kindly do more effort to explain the new introduced concepts in both java and kotlin .. and don't act like you don't care about java developers anymore .. this is disrespectful. both have the right to get detailed explanations in both your live shows and learning videos.. not everyone have the luxury to learn a new programming language just to integrate new introduced components to an existing project .. and if your documentation do so .. it is just Not enough as we deal with more serious stuff in the real world.. the docs only shows basic stuff.

  5. If you're going to deprecate things like loaders, either use Java in your slides or use pseudocode. You told me in a video I should be using loaders in Java, so why isn't your retraction in Java too? As my ASD is likely to prevent me from ever understanding Kotlin as it lacks the syntax of other programming languages, YouTube search suggests my only option to understand LiveData is to learn Hindi.

    Perhaps a random video in Hindi will do a better job at explaining it than you are, because unlike spoken language, programming languages like C, C#, Java, Python, and PHP, are all somewhat similar visually, and while YouTube may be a tad awful at subtitling videos, there's more chance of Auto-Translate being intelligible than Google releasing the Java slides.

    If you're going to insist on using Kotlin in all your slides, please add programming languages to Google Translate's live image translation feature. At the moment you are like a country with two official languages that is discriminating against people that only understand one of the languages… so a bit like Cameroon.

    Linguicism: "ideologies and structures which are used to legitimate, effectuate, and reproduce unequal division of power and resources (both material and non-material) between groups which are defined on the basis of language" –Tove Skutnabb-Kangas

    "There are different forms of linguicism. Overt linguicism is exemplified by the prohibition of the use of particular languages for instruction. Covert linguicism is illustrated by de facto non use of certain languages as languages of instruction, even if their use is not explicitly forbidden." –William Velez

  6. In 00:40 instead of saying the UI will be notified, you should have said the observer method will get notified.
    Maybe the programmer wants to do something else instead of changing the UI.
    What do you think about it?

    I appreciate your suggestions.

  7. it took me 3 minutes to figure out that the person speaking is a women 😀 i am slow as Android Studio in my machine

  8. Kotlin's been "officially supported language for Android development" since 2017's I/O, it's been a year, surely we can pick it up by now 😀

  9. All these great new features coming but examples on kotlin, becoming really hard to relate to this. been developing android apps for years but still, seeing the unfamiliar code of kotlin makes it kinda harder to instantly pick the concept and grasp it. Along with learning the concept i feel like i have to learn a whole language as well, making things more complicated for no reason.

  10. While Kotlin may be a good functional object oriented programming language, a vast majority of android developers are Java developers and among them, a lot of them use Java for other purposes as well. This means that all these people(at least the vast majority) are more familiar with the imperative style of programming rather than functional.
    It would be rather beneficial for the majority if the sample code in the videos are in Java. A change this fast is quiet difficult to adapt to.
    Thank You.
