android studio cannot compile when using realm database

Question

I want to use realm database in my app for that i add this lines to my build.gradle file in app

apply plugin: 'realm-android'
buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "io.realm:realm-gradle-plugin:1.1.0"
    }
}

and this is my table code:

public class Country extends RealmObject {
@Ignore
public static String NAME="name";
@Ignore
public static String POPULATION="population";
@PrimaryKey
private String name;
private int population;

public Country() { }

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getPopulation() {
    return population;
}

public void setPopulation(int population) {
    this.population = population;
}

}

but when I use this code and nothing else "I mean never use country table" I getting this error when run my app:

    }

    repositories {
        maven { url "https://jitpack.io" }
    }
}

    classpath "io.realm:realm-gradle-plugin:1.1.0"
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
}


task clean(type: Delete) {
delete rootProject.buildDir
}

Can you post your `build.gradle` file? – Christian Melchior Aug 01 '16 at 07:15 — Christian Melchior, Aug 01 '16 at 07:15
Try to do `./gradlew assemble --refresh-dependencies` – geisshirt Aug 01 '16 at 11:09 — geisshirt, Aug 01 '16 at 11:09

Thanks all For your attentions but I found my solution.
I add this lines to my project Gradle file:

allprojects {
repositories {
    jcenter()
    maven {
        url 'https://github.com/uPhyca/stetho-realm/raw/master/maven-repo'
    }

}
}

and this to my app gradle file

compile 'com.uphyca:stetho_realm:0.9.0'
compile 'io.reactivex:rxjava:1.1.0'
compile 'com.facebook.stetho:stetho:1.3.1'

I don't know why I should add this lines and realm documentation never refer to this but know my project works fine.
I know this is wired behavior but its work.
please share me if you know a better answer.

What if you use RxJava 2 and just cannot add first rxjava to `build.gradle`? – sasha199568 May 18 '17 at 15:21

Updating JDK to version 1.8.3 solved the issue. JDK can be downloaded from

http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Setting up JDK on android can be done using How to set Java SDK path in AndroidStudio?

This should be the accepted answer. The current one seems to be a hard workaround and it does not work for me. – tuncay altınpulluk May 02 '17 at 21:20

This is how I solved the problem:

1.) Create a new package and name it rx 2.) Inside this package add a class named Observable, empty class.

It compiles fine now.
