Actual Results

Steps & Code to Reproduce

This is when I start up the application, I need to know if it exists an order unfinished. I have tried these things already.

1.Clean and rebuild project. 2.Deleted generated build files manually. 3.Uninstall app before deploying. 4.I have realm in my project gradle and app gradle. (version 1.1.0) 5.I have tried with Order extending RealmObject and implementing RealmModel. 6.RealmConfiguration has deleteRealmIfMigrationNeeded.

Code Sample


         RealmConfiguration realmConfig = new RealmConfiguration
            .Builder(getApplicationContext())
            .deleteRealmIfMigrationNeeded()
            .name("myRealmFile")
            .build();

        Realm.setDefaultConfiguration(realmConfig);            

        Realm realm = Realm.getDefaultInstance();

        RealmResults<Order> orders = realm.where(Order.class).equalTo("finished", false).findAll();

        mHasActiveOrder = orders != null && orders.isValid() && orders.size() > 0;

        realm.close();

Version of Realm and tooling

Realm version(s): 1.1.0

Android Studio version: 2.1.2

Which Android version and device: API LVL 24 with Android Moto G with API LVL 22.

@luna-vulpo that you should use kapt instead of annotationProcessor, and that you should execute kotlin-android before realm-android

Generally it should look like this

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'realm-android'

My guess goes for that you should disable Instant Run in Android Studio.

If you’re implementing RealmModel, then if I know correctly you also need to add the @RealmClass annotation. However, it’s worth noting that this should work out of the box if you’re extending RealmObject, so I think instant run is messing things up.

Should be File -> Settings -> Build Execution Deployment -> Instant Run and you should make sure Enable instant run is unticked.

Ah yes, if you don’t add the default proguard, then you need to specify that keep * extends io.realm.RealmObject or something like that

I have something similar. Please let me know if i should open new issue or continue here.

io.realm.exceptions.RealmMigrationNeededException: The MyUserRealm class is missing from the schema for this Realm.

This is my setup: Android Studio: 2.1.2 Language: Kotlin 1.0.3 Realm: 1.0.1 Gradle plugin: 2.1.2 Gradle wrapper version: 2.14 Android target API Level: 24 Android compile SDK: 24 Build tool version: 24.0.0 Instant Run: Disabled Testing device running: Android 4.3 Apk is release mode debugable.

First install normal, but the second build will reproduce the error.

If you need more information please let me know.
