Realm.init（）无法解析方法init在Application onCreate中不起作用？

Question

Can't call init() method on Realm. Any ideas what I'm doing wrong?

I have added the dependency in my build.gradle(project):

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.1'
        classpath "io.realm:realm-gradle-plugin:3.2.0"

    }
}

and applied the plugin in the build.gradle(app)

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

So I made it work with Realm.init(MyApp.this) . I think the issue is you have the dependencies inside the build.gradle of the whole project. This:

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
    mavenCentral()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.3.2'
    classpath 'com.google.gms:google-services:3.0.0'
}
}

allprojects {
repositories {
    mavenCentral()
}
}

When you should have it inside the build.gradle of your app: Like this:

buildscript {
repositories {
    maven { url 'https://maven.fabric.io/public' }
    maven { url 'http://dl.bintray.com/amulyakhare/maven' }
    maven { url 'https://jcenter.bintray.com/' }
    maven { url "https://jitpack.io" }
}

dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
    classpath "io.realm:realm-gradle-plugin:3.2.0"
}
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'realm-android'

repositories {
maven { url 'https://maven.fabric.io/public' }
maven { url 'http://dl.bintray.com/amulyakhare/maven' }
maven { url 'https://jcenter.bintray.com/' }
maven { url "https://jitpack.io" }
}


android {
compileSdkVersion 23
buildToolsVersion '25.0.0'
defaultConfig {
    applicationId "nl.hgrams.passenger"
    minSdkVersion 17
    targetSdkVersion 23
    versionCode 900
    versionName '2.8.2'
    multiDexEnabled true
}
...
}

It seems like a lagg at Android Studio indexes system. Try next solutions:

1. Sync gradle files
2. Invalidate IDE indexes and restart
   

3. And the last assumption - move io.realm:realm-gradle-plugin:3.2.0 dependency from project build.gradle file to build.gradle from app and define own buildscript section:

    buildscript { repositories { jcenter() } dependencies { classpath 'io.realm:realm-gradle-plugin:3.2.0' } } 

   Autogenerated build.gradle for project contains next note about this:

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