Realm 文件夹就位，注释处理器在 libs 文件夹中

设置.gradle

include ':app', ':realm'

构建.gradle

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'

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

allprojects {
    repositories {
        jcenter()
    }
}

应用构建.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "appwise.be.gsontestproject"
        minSdkVersion 11
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    //compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:20.0.0'
    //gson
    compile 'com.google.code.gson:gson:2.3'
    //realm
    apply plugin: 'com.neenbedankt.android-apt'
    compile project(':realm')

    compile fileTree(dir: 'libs', include: ['*.jar'], exclude: ['realm-annotations-processor*.jar'])
    apt fileTree(dir: 'libs', include: ['realm-annotations-processor*.jar'])
}

我正在尝试将它与 GSON 结合使用。 这看起来像一个很棒的数据库工具(我最近对它进行了简短的测试)， 但在这个项目中，它无法工作。

答案在这里: Getting io.realm.exceptions.RealmException: Could not find the generated ValidationList class when trying to get a Realm object

帮不了我。

Answer 1

你有

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

在您的依赖项定义中，这可能是我怀疑会触发注释处理器的原因。应该在外面。

另外，Realm 0.71 刚刚在 JCenter 上作为一个 jar 发布，所以理想情况下你应该拥有

compile 'io.realm:realm-android:0.71.0

在您的依赖项中，而不是您现在使用 apt 的依赖项。 你可以在这里看到更多:http://realm.io/docs/java/0.71.0/

简而言之，您的依赖项部分应如下所示:

dependencies {
    compile 'com.android.support:appcompat-v7:20.0.0'
    compile 'com.google.code.gson:gson:2.3'
    compile 'io.realm:realm-android:0.71.0'
}
