android - 无法解析配置 ':app:_debugCompile' 的所有依赖项

Question

我正在尝试在我的 Android 应用程序上使用 Google map 。我安装了 Google Play 服务并获得了 API key 。我不明白为什么会收到此错误消息!我认为它提示以下内容。

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

错误信息:

  Error:A problem occurred configuring project ':app'.
    > Could not resolve all dependencies for configuration ':app:_debugCompile'.
       > Could not find com.android.support:support-v4:22.0.0.

Answer 1

显然它正在寻找 v4 (com.android.support:support-v4) jar。你的构建路径中有它吗？

对于 android studio，在 dependencies block 中的 gradle 文件中，添加以下行 -

dependencies {
    compile 'com.android.support:support-v4:22.0.+'
    // your other dependencies as well

}

并确保您已经通过 SDK 管理器下载了 Android 支持库。如果您还没有，请引用官方文档 Support Library Setup
