无法使用实时-android 库

Question

我想将这个 realtime-android 项目用作我的 Android 项目中的一个库，但是当我尝试导入这个项目时，它给了我这个 "No projects are found to import"。

那么如何将它用作图书馆呢？谢谢您的帮助。这是 build.gradle:

apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':appcompat_v7')
    compile project(':gridlayout_v7')
    compile 'com.goodow.realtime:realtime-android:0.5.0'
}

android {
    compileSdkVersion 20
    buildToolsVersion "20.0.0"

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

根据 Maven Repo，您可以将其包含在 build.gradle 依赖项部分。

我注意到您缺少 repositories 部分，因此您可能需要添加它。例如，这是我的 build.gradle。

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
    }
}

apply plugin: 'com.android.application'

repositories {
    jcenter()
}

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    // ... other stuff

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.android.support:appcompat-v7:23.2.1"
    compile "com.android.support:design:23.2.1"

    // this line
    compile 'com.goodow.realtime:realtime-android:0.5.0'

}

或者您可以使用“下载 JAR”按钮并将其放入项目的 libs/ 文件夹中。
