Realm 0.88.2 example : Cannot resolve symbol

I downloaded this : https://static.realm.io/downloads/java/realm-java-0.88.2.zip Then imported the "examples" folder inside Android Studio.

I can run examples but Android Studio cannot resolve symbols for Realm classes.

Is there something missing in this example project ? I want to enable completion.

enter image description here

Edit :
When I add "compile 'io.realm:realm-android:0.87.5'" to the build.gradle, this error occur :

Solution

  • Since v0.88.0, you need to use the AAR configuration (using Gradle), by adding the Realm plugin to the application classpath and applying the plugin.

    buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "io.realm:realm-gradle-plugin:0.88.2"
    }
}

apply plugin: 'realm-android'
