guys, is it safe to use google chrome tabs to replace webviews?

is it possible to have non-argument and argument constructors using the constructor syntax example:

class DownloadHelper(internal val tag: String = "") : Fragment()

It breaks if you put business logic into your layouts. You can use databinding fine if you don’t do just that

Anybody tried the new Parcelable feature on 1.1.4? I am getting this error “This class implements Parcelable but does not provide a CREATOR field less... (⌘F1)” also doesn’t build with a similar error.

anyone here using the

@Parcelize

annotation from the 1.1.4 android extensions? It doesn't seem to work for me, I always get a compiler error:

error: cannot find symbol CREATOR = null

I use a live-template in Kotlin for this...

class $NAME$ @JvmOverloads constructor(
        context: Context,
        attrs: android.util.AttributeSet? = null,
        defStyleAttr: Int = 0
) : $SUPER$(context, attrs, defStyleAttr) {


    init {
        $END$
    }
}

When I use mockito to mock one of the java classes in kotlin test . It doesn’t look like it is mocking. Anyone else had similar?

08/18/2017, 12:55 PM

I have to say, new kapt is mess. I am using Dagger, etc, have modules app, ui and lib and when I make change in lib, I need to do full rebuild(13 minutes) because of kapt errors. Every fckin change must be full rebuild. I am using 1.1.4

you could use a delegated property to at least hide away the nasty to single place

08/18/2017, 3:45 PM

Wouldn’t this work?

extras
    .getParcelableArray(LocationPicker.INPUT_POLYGON)
    .filterIsInstance<LatLng>()
    .forEach(inputPolygon1::add)

Try kotlin 1.1.4-2? It was just released to fix a few high priority issues..

myanmarking

08/18/2017, 5:36 PM

guys, when creating a RoomEntity, you can use kotlin data classes with vals and room will use the constructor. but if you have a custom type requiring a Converter, you cannot use vals but need vars. is this supposed to be right, or just a bug?

Hey all! How can I injected in

@feroz_baig it depends on serialization library which you use with retrofit. But for most libraries it is not important.

That doesn't sound like an argument or a joke. Could you elaborate why some choices are better than other?

08/20/2017, 6:25 AM

Mostly meant a joke, but it is also tragically real. A vast majority choose things such as DB abstractions based on how easy things like the minimum viable integration is. And that's easy. Making things that require no code and solve contrived examples in almost no lines of code seduces you in. Then inevitably the complexity grows at a rate much higher than if you had picked something less sexy but better designed to scale. I'm sure it's true everywhere, but it feels like and especially bad problem for Android libs.

It was pretty obvious it was a joke 😀

Thanks Jake 🙂 The problem in my opinion is that “Use our DB, see how it is easy” what you are against is pretty much the same as you saying “people have bad taste” over their DB, especially given who was saying that. But explanation makes sense, if only it could be a little bit more specific. I’m not against opinions, no, but I believe when saying “don’t use X, use Y” adding “because A and B” is much much better.

Jokes apart, what is the solution that covers Jake’s requirements best? [BTW, I’m sure there are bad libraries out there, but most of the Android API itself is horrible.]
