Can not annotate with R constants

[Pomis]

Having strange bug: Trying to use it like this

@Layout(R.layout.section_item)
class SectionPlaceholder(private val section : Section) {

    @View(R.id.title_textView)
    lateinit var tvTitle: TextView

    @View(R.id.content_textView)
    lateinit var tvContent: TextView

    @Resolve
    fun onResolve() {
        tvTitle.text = section.title
        tvContent.text = section.content
    }
}

But Studio underlines all R.layout/R.id usages and says that An annotation argument must be a compile-time constant. If I try to compile, I get:

 error: incompatible types: <null> cannot be converted to int
@com.mindorks.placeholderview.annotations.Layout(value = null)
                                                         ^

If I use generated constants it fails with runtime exception (res not found)

@Layout(0x7f0f0023)
class SectionPlaceholder(private val section : Section) {

    @View(0x7f0c0071)
    lateinit var tvTitle: TextView

    @View(0x7f0c0020)
    lateinit var tvContent: TextView

    @Resolve
    fun onResolve() {
        tvTitle.text = section.title
        tvContent.text = section.content
    }
}

Used versions:

implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.mindorks.android:placeholderview:1.0.3'
kapt 'com.mindorks.android:placeholderview-compiler:1.0.3'

If I use old version (0.7.3) I have the same issue Used plugins:

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

kotlin version: 1.2.51. Everything works with usual RecyclerView

did you ever get this working? i'm surprised no one else has mentioned this issue since it immediately happened when i tried to use the project.

[Pomis]

No I decided to use vanilla RecyclerView in that project. Maybe issue was caused by multi module architechture, I don't know

Cannot use an annotation in library module to bind to a resource in app module. Because, All of library will be build and process annotation before build app module. So that, the resource id always is 0. Another workaround: Step 1: Disable all of libraries that poiting to resource: Butterknife, PlaceHolderView,... Step 2: Build app module and copy R.java to the same package name in library module Step 3: Reenable above libraries and then rebuild

Thank you sir. This method work for me. But AS now not show R.java. Need decompile apk and get R.java file. And after some changes in res files AS change some id rebuild and will be crashed (

Found a working solution. Change module lib to dynamic future module.
