Android ORMs: Can't recognize method in annotations

Question

In my Android app I'm trying to implement ORM for SQLite database for existing db. I've tried to implement activeandroid and DBFlow, but Android studio shows error that it can't recognize method. Here's how it shows when I try to use DBFlow ORM and similarly for activeandroid it doesn't recognize methods in annotations. The red in below screenshot is error. It says it can't recognize method databaseName and also constant PRIMARY_KEY doesn't exist.

Here's project build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

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

And here's app: build.gradle

apply plugin: 'com.android.application'
apply plugin: 'android-apt'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
