Question

我下载了这个： https://static.realm.io/downloads/java/realm-java-0.88.2.zip 然后导入＆＃34;示例＆＃34; Android Studio中的文件夹。

我可以运行示例，但Android Studio无法解析Realm类的符号。

此示例项目中是否缺少某些内容？我想启用完成。

编辑：
当我添加＆＃34;编译＆＃39; io.realm：realm-android：0.87.5＆＃39;＆＃34;到build.gradle，发生此错误：

Answer 1

从v0.88.0开始，你需要使用AAR配置（使用Gradle），将Realm插件添加到应用程序类路径并应用插件。

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

apply plugin: 'realm-android'

Answer 2

尝试将此包含在build.gradle文件中的依赖项中，如：

compile 'io.realm:realm-android:0.87.5'

这是没有Gradle插件时提供的最后一个版本。

问题来自main build.gradle。

替换它：

allprojects {
    def currentVersion = file("${rootDir}/../version.txt").text.trim()

    buildscript {
        repositories {
            mavenLocal()
            jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.6'
        classpath 'com.jakewharton.sdkmanager:gradle-plugin:0.12.0'
        classpath 'com.novoda:gradle-android-command-plugin:1.5.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath "io.realm:realm-gradle-plugin:${currentVersion}"
    }
}

group = 'io.realm'
version = currentVersion

repositories {
    mavenLocal()
    jcenter()
}
}

通过以下方式：

buildscript {
def currentVersion = file("${rootDir}/../version.txt").text.trim();
repositories {
    mavenLocal()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
    classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.6'
    classpath 'com.jakewharton.sdkmanager:gradle-plugin:0.12.0'
    classpath 'com.novoda:gradle-android-command-plugin:1.5.0'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    classpath "io.realm:realm-gradle-plugin:0.88.2"
}
}
allprojects {
    group = 'io.realm'
    version = "0.88.2"

    repositories {
        mavenLocal()
        jcenter()
    }
}
