Android Eclipse 在哪里 android-support-v7.jar

Question

我使用 Eclipse 和 Android。我创建了一个新项目，但在 java 类中出现以下错误

import android.support cannot resolved.

---

这是我的 SDK 管理器屏幕

我安装了 Android 支持存储库。

我想将 android-support-v7.jar 添加到我的项目中。但是我没有文件夹 android-sdks\extras\android\support\v7\

我有文件夹

android-sdk\extras\android\m2repository\com\android\support

是同一个文件夹吗？如何将 android-support-v7.jar 添加到我的 Eclipse 项目中？

android {
    compileSdkVersion 19

    sourceSets {

            manifest.srcFile 'AndroidManifest.xml'

            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')
    }
}

怀疑您也在使用 maven 作为构建工具，请将m2repository添加到您的项目中，例如：

<repositories>
    <repository>
        <id>android-support</id>
        <url>file://${env.ANDROID_HOME}/extras/android/m2repository</url>
    </repository>
</repositories>
    ......
<dependency>
    <groupId>com.android.support</groupId>
    <artifactId>support-v4</artifactId>
    <version>19.0.1</version>
</dependency>

参考：Android support library setup with maven

你必须相应地调整env.ANDROID_HOME和artifactId、version。
