    It was so interesting to see how Context retrieved in Presentation being shown on the secondary display is different from the one retrieved in its parent Activity which is shown on the main display - they had different resource configuration, so on the smaller secondary display hdpi drawables were used, while on the main display they were xxhdpi 🙂

    Thanks Philip for the informative video! Any chance you could discuss how to access the context in a Fragment? If I am correct, requireContext() should be used. However, sometimes I noticed that the Fragment might not be attached to a context, leading to an IllegalStateException. It would be nice, if you could discuss how to use context in a Fragment in general, what context to use, and what issues may arise. Thanks again for the great video!

    • @PhilippLackner
      @PhilippLackner  Рік тому

      requireContext is correct, but the Fragment needs to be attached to the activity, so you can't use it in a global variable for example without lazy

  • @neoplaygame
    @neoplaygame Рік тому

    Nice video! and another reason to use activity context over application context is when user changed system language, only activity will be recreated and the application won't. so if you use getString() with activity context will have the updated language and application context won't. correct me if I am wrong.

    • @PhilippLackner
      @PhilippLackner  Рік тому +1

    Do you know why there is no context in desktop apps, for example all I need to read/write a file is to create a File object and pass the path then create something wraps that File object

    • @cursedfunction

      Context, as described in this video, is an Android specific paradigm. You could create your own concept of “Context” in a desktop application.

  • @huskar1u3

    7:28 Why viewModel isn't destroyed before the activity is destroyed? Wouldn't we avoid a memory leak, in this case a context?

    • @PhilippLackner
      @PhilippLackner  Рік тому +2

      The whole purpose of a viewmodel is to outlive the life cycle of the activity, check the previous video 😄

    • @huskar1u3
      @huskar1u3 Рік тому

      ​@@PhilippLackner Thank you! So, in this case the memory leak will occur only if we change the screen orientation and the activity is not permanently destroyed, right? But if we navigate away, the viewModel will be destroyed along with the activity?

    • @jayshartzer844

      Most Android jobs have to deal with both legacy and modern development tools and techniques. Also, Context is used everywhere.

  • @abacaabaca8131
    @abacaabaca8131 Рік тому +1

    From my understanding "native
    android developer" means somebody that can transform his code into the selective android processor' machine code. For example, in android, the CPU could be ARM architecture, or other architecture. So, their technique might differ for different CPU, like what library to link etc. Not to mention that android have different type of operating system too if not mistaken.
    But for us that knows kotlin, we can let JVM settle this issue of handling different CPU architecture.
    We just focus on our code testing, the unit testing, android testing.
    But honestly I wanted to learn Gradle first without android studio only Gradle and kotlin,
    and try to use different dependencies out there.
    Currently working on to parse object file for 3d rendering without tutorial. The only guidance is from C++.

    • @solarseraph
      @solarseraph 10 місяців тому +2

      Quick note for you: a native Android developer is anyone who writes an app for Android only, directly with Android's Java or Kotlin libraries. A non-native developer would write code in a framework like Flutter or React that cross compiles to Android/iOS/other, and abstracts away the details of Android-specific concepts like Context or the onCreate/onDestroy lifecycle. It is "native" with respect to the operating system, not the hardware- the same could be said for a native Windows or iOS app. Hope this helps!
