Hi, anyone here who migrated from Glide image loading library to Coil? I'm considering replacing Glide due to performance reasons. Animations stutter when Glide loads an image at the same time. I'm wondering if Coil handles this better?

Question regarding separation of concern in clean architecture: I have the following layer in my app: 1. UI 2. Presentation 3. Usecase 4. Repository 5. Data layer(Remote & Local data source) Now I get a

JSONArray

from the remote data source. For simplicity the

JSONArray

consist of a list of the following `JSONObject`:

{
 "id": 1,
 "type": "city",
 "url": "<http://xyz.com/berlin.png>",
 "section": "world",
}

In my UI I want to show only list of Images. My UI should not get all a model which consist of

URL

. In which layer should I use a mapper to convert the

ModelEntity

to a

Model

which consists of

URL

only?

how do I convert

MutableLiveData

to

Observable

?

Hey, How to get a `view`’s tag in Appium? I don’t want to set a content-description for to differentiate the content of a

view

.

Are DialogFragments supposed to be dismissed on device rotation? I'm using Navigation. Nav graph goes from Fragment A -> Dialog B (this is a dialogfragment). When I rotate device on Dialog B, it dismisses the dialog and goes back to Fragment A. I'm expecting Dialog B to stay on screen through device rotation. Has anyone come across this problem?

Hey I'm learning Kotlin using the Kotlin_Koans IDE course in Android Studio. I've just done a task about Data Classes but I'm so confused by what this class is supposed to be doing. It's comparing two names that are the same, despite having two different names in the list, why? I'll copy the correct answer below, then underneath I'll paste the 'task'. data class Person(val name: String, val age: Int) fun getPeople(): List<Person> { return listOf(Person("Alice", 29), Person("Bob", 31)) } fun comparePeople(): Boolean { val p1 = Person("Alice", 29) val p2 = Person("Alice", 29) return p1 == p2 // should be true }

Please check out CoC. https://github.com/JetBrains/kotlin-web-site/blob/master/pages/community/slackccugl.md You should put your code in ```

Hi! Is it possible to use Java 11 with Android Development or Do I need to stick with the Java 8 yet?

using jetpack's navigation graph, is there a way to pass safe args to a destination? (not directions)

@here Is it possible to set layout_height or layout_width for a view using data binding. Tried SO but didn't work.

Is there any “strict mode” to check if I edit some view outside the main thread? I’m getting some strange crashes that doesn’t point to any line of my code. I think that those errors are related with a

notifyDataSetChanged

or a

setText

performed outside the main thread. The problem is that the app is huge and those errors are race exceptions so they are not easy to reproduce. For that reason I’ll need some “tool” that checks that all the interactions done with view is done in the main thread. Any idea?

does anyone remember when android studio, when using the key combo of Cmd/Ctrl + Shift + Up/Down, would move a line of code up or down manually? In some recent update it tries to make some assumptions on where u would like the code to go, like if the line enters in the scope of a function it would jump above the function. am i able to revert to the old functionality somehow

Hey guys, I left you here an Android base project(open source) to use as a template. https://github.com/rootstrap/android-base You can collaborate with new functionalities that are essential when starting a new project. 👍

Hello everyone! I have some problem which really causes me headache and trying to find a solution for this. I also created a question on StackOverflow but it seems not getting any attention. So maybe someone can help me with it? It would be really kind. https://stackoverflow.com/questions/59888640/android-hiding-revealing-bottom-navigation-view-causes-lost-of-scroll-state

Hi fellow droidheads! I've come across a new challenge with AndroidX Fragments and live data and I wonder if you can confirm the following 'rules': - If you use

androidx.fragment

artifacts v1.2.0 and up, AND - If you observe

LiveData

in fragments, AND - If that fragment does inflate a view in

onCreateView

AND - If that view is not null THEN use

viewLifecycleOwner

to observe live data. OTHERWISE use the fragment itself, which is a

LifecycleOwner

, to observe live data. Is this correct?

Folks remember, real devs go native! None of that flutter or react bs.

Do in app updates only work in Fragments?

Hi everybody , When will a coroutine flow be less experimental? If anyone knows please tell me

Hey guys, does anyone have some interesting (preferably well written) Android project that could make a fun exercise to write tests for? (or any other suggestion on how to improve writing tests)

Hi everyone 👋 How does the Android DI library hold singleton objects? For example, Dagger, Koin, etc. are stored internally just by passing Context. I want to know the internal processing. We also to be aware garbage collection 😢

Hello 👋 Many times a day I get compile error

<http://java.io|java.io>.FileNotFoundException: .../android-application/app/build/tmp/kotlin-classes/beta/META-INF/app_beta.kotlin_module (No such file or directory)

I tried to disable R8 minification, but it did not helped 😢 . Any ideas ? 👂

I just hit a weird thing: our app would crash with the following error:

java.lang.LinkageError: Method void com.example.h72.a() overrides final method in class Lcom.example/de; (declaration of 'com.example.h72' appears in base.apk)

. That’s after obfuscation with R8. The cause was we’d have the following class hierarchy:

androidx.lifecycle.ViewModel <- BaseViewModel <- SomeViewModel

, and in

SomeViewModel

we’d have a

fun clear() { }

method. However, method with same name and signature appears in `androidx.lifecycle.ViewModel.java`:

final void clear()

. What I quite don’t understand is, why everything works without R8? I clearly see

public final void clear()

method in the decompiled

SomeViewModel

, and so feels like things should crash straight away. What happens instead, app works fine without R8 and only crashes with it. 😕 Any idea what might be the reason?

When representing a width-height combo, is there any advantage (other than interactions with other code requiring

Point

) to using

Point

instead of

Pair<Int, Int>

? I’m preferring

Pair

(because of destructuring and also not being Android-specific) but since I’m creating potentially tens of thousands of these objects, I wanted to check if there is any performance issues.

I haven't done Android development in a long while and I am trying to build a little demo app and Android Studio says Android module missing. I'm stumped is there anyone who can take a look at https://github.com/open-jumpco/kfsm-android and tell me what is missing?
