After upgrading to gradle plugin 3 and gradle 4, my unit tests that use robolectric are all failing with the following NPE:

@User uploaded a file: Untitled

My solution: Disable AAPT2 in gradle.properties as they package resources in a way that robolectric currently does not support

Anyone used Room? Having issue with TypeConverter converting my

java.util.date

.

class DateTypeConverter {
    companion object {
        @TypeConverter
        fun fromTimestamp(value: Long?): Date? {
            return if (value == null) null else Date(value)
        }

        @TypeConverter
        fun dateToTimestamp(date: Date): Long {
            return date.time
        }
    }
}

and my compiler reporting:

DateTypeConverter.java:3: error: Class is referenced as a converter but it does not have any converter methods.

and my article entity looks like this:

@Entity(tableName = "articles")
data class ArticleDb(@ColumnInfo var articleId: String,
                     @ColumnInfo var date: Date) {
    @ColumnInfo
    @PrimaryKey(autoGenerate = true) var id: Long = 0
}

Any ideas whats wrong?

im defining the

@TypeConverters(DateTypeConverter::class)

in the Dao

Have you tried annotating the methods with @jvmstatic similar to how it works with parcelable?

Just shooting in the dark here though

I tried kotlin spek test on android but I got the following error Error:Conflict with dependency 'org.jetbrains.kotlin:kotlin-stdlib' in project ':app'. Resolved versions for app (1.1.2-5) and test app (1.0.6) differ. any solution?

Hi, I figured I would try out Kotlin on Android, but I don’t see the checkbox for “Include Kotlin Support” when creating a new project. AS says it’s up to date, but do I need a beta version of AS or something?

you need AS 3.0 for that which is still in canary

Cool. Is there a brew cask for that?

You just need to add the Kotlin plugin to AS.

O

Uhh

Hi guys, is there a specific reason why in Kotlin when defining @IntDef() it requires Long values and not Int values?

Kotlin just not allows to convert int to long automatically, like Java does.
