Version of Realm and tooling

Realm version(s): 4.1.1 . I had to tried with versions: 3.7.2, 4.0.0, 4.1.0 most also meet the same error

Realm sync feature enabled: no

Android Studio version: 3.0.0

Which Android version and device: SamSung j7 prime os android 7.0

[beeender]

  // Realm
  compile "io.realm:realm-android-library:$realm_version"
  compile "io.realm:realm-annotations:$realm_version"

This two lines need to be removed. The recent realm-java don't need this in the app's build.gradle anymore.

[oLeMinhQuang]

@beeender Thanks for quickly support. I have removed 2 lines you suggest but it still has the same error above

[beeender]

how does your project level build.gradle look like? Also, try to do a full clean before rebuild to test.

[oLeMinhQuang]

@beeender I also full clean before rebuild but it's not working, same error.

apply plugin: 'kotlin-kapt' is missing after apply plugin: 'kotlin-android'

[oLeMinhQuang]

@Zhuinden I tried to add apply plugin: 'kotlin-kapt' it still same error. :(
@beeender I find out the android test class cause the error look like this:

@RunWith(AndroidJUnit4::class)
    class DeleteByContentIdTest : Base() {
        @Before override fun setup() {
            Realm.init(context)
        }

        @After override fun teardown() {
        }

        val contentIds = longArrayOf(98765L, 12345L)
        val contentCaches = Array(contentIds.count(), {
            RealmContentCache(
                    contentId = contentIds[it],
                    cacheData = contentIds[it].toString())
        }).toList()

        @Test fun test1() {

            InstrumentationRegistry.getInstrumentation().runOnMainSync {
                Realm.deleteRealm(realmConfig)
                realm = Realm.getInstance(realmConfig)
                subject = RealmContentCacheRepository(realmConfig)

                realm.executeTransaction { realm ->
                    realm.copyToRealm(contentCaches)
                }
                try {
                    subject.delete(contentIds[1])
                            .done {

Could you help me check those functions is there wrong within Realm 4.1.1?
Exception error relate to RealmThumbnail.kt class i posted above:
java.lang.AssertionError: something wrong io.realm.exceptions.RealmException: 'class com.company.android.ebook.bookshelf.realm.RealmThumbnail' is not part of the schema for this Realm.
So is this class allow to use with Realm 4.1.1?

You must also make sure that when you add kotlin-kapt, then it is applied BEFORE realm-android.

@Zhuinden my build.gradle like that;

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'realm-android'
apply plugin: 'io.fabric'
apply plugin: 'com.cookpad.android.licensetools'

I also add for both module app and ebook because both of them use realm lib

[oLeMinhQuang]

I think the class android test error that i posted above may not to use correct way with Realm 3.7.2. or higher. If i remove it and execute ./gradlew connectedCheck that is absolutely success .

Thank you @beeender @Zhuinden for yours support.
Finally we have found wrong point in my internal code so i will close this issue
