    Many operations with 
    IntRange
    are optimized at compiler-level. 
    i in 0..N - 1
    can be aslo written as 
    i in 0 until N
    , and someone said that this is also optimized (I have troubles in finding it in history).

    is there a better way of taking care of request q (with Rx and Retrofit) (and not worring about users actual connectivity) than SyncAdapter?

    its not available for api 16, isn’t it?

    GcmNetworkManager is like some sort of backport of JobScheduler for lower api levels

    it internally uses JobScheduler on >=Lollipop

    @scoot as others have said, some loop operations are optimized to not actually create an in 
    IntRange
    . to be sure, you should check the built-in byte code viewer. in any case, if you use anko, there is an extension function 
    List.forEachByIndex
    that you can use to iterator over a list without creating garbage

    or these @mzgreen @rudolf.hladik https://github.com/evernote/android-job https://github.com/hypertrack/smart-scheduler-android For me the android priority jobqueue lacked some parameters for periodic jobs and device states

    Hi, is it ok if an override fun in customview can't access private string value when it is call by xml view property (don't know if what I say i understandable). In fact it works when i try with a boolean var (also I can access to it in my constructor / random fun I call programmatically)

    a code snippet and the respective error message would be helpful

    Copy code
    class TwoColorsTextView : HtmlTextView{

    private var separator: String = "jboiubombobumb"

    private var test: Boolean = true

    constructor(context: Context) : this(context, null)
    constructor(context: Context, attrs: AttributeSet?) : this(context, attrs, 0)
    constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr) {}

    override fun setText(text: CharSequence?, type: BufferType?) {
        try {
            Log.d("test", test.toString())
            Log.d("test", separator)
            
        } catch (ex : IndexOutOfBoundsException){
            super.setText(text, type)
        }
    }
}

    And my xml :
    Copy code
    <TwoColorsTextView
                                android:id="@+id/vBLCl"
                                style="@style/Missions"
                                android:layout_width="wrap_content"
                                android:layout_height="wrap_content"
                                android:text="@string/holder.formula" />

    The second log (string attribute) return a nullpointerexception

    12/07/2016, 10:54 AM
    it's possible that the super class' constructor calls this method
  • k

    kirillrakhman

    12/07/2016, 10:54 AM
    at which point the property is not yet initialized
  • k

    kirillrakhman

    12/07/2016, 10:54 AM
    you should print out the stack trace
  • k

    kupris

    12/07/2016, 10:56 AM
    I will check that, thanks 🙂
  • k

    kupris

    12/07/2016, 10:59 AM
    But what I don't understand is why the boolean is log successfuly in this case
  • k

    kupris

    12/07/2016, 11:00 AM
    the two attributes aren't define in parent and his subparent (default textview)
  • k

    kupris

    12/07/2016, 11:01 AM
    but yeah if I specify android:text, it's the text setter from textview which is call so

    12/07/2016, 11:15 AM
    It works with a null checker in my setter but it's a bit dirty ><

    you're testing the string first
  • k

    kirillrakhman

    12/07/2016, 11:24 AM
    the boolean is initialized to it's default value (
    false
    ) before its value is set
  • k

    kirillrakhman

    12/07/2016, 11:25 AM
    the string is initialized to 
    null
  • k

    kupris

    12/07/2016, 11:42 AM
    right, it doesn't return true. I think I have to learn about object instantiation 😅
  • k

    kirillrakhman

    12/07/2016, 11:42 AM
    this is actually a rather tricky corner case
  • k

    kirillrakhman

    12/07/2016, 11:45 AM
    you could argue that it's the super class' fault because it calls a non-final method in the constructor

    this is discouraged and there is even an inspection for Kotlin
