Answer 1

您应该将Android Repository do更新为：

1. 打开SDK Manager
2. Android支持存储库
3. 安装包



在Android Studio 2.0中，您可以在以下位置找到：

工具 - ＆gt; Android -SDK Manager 菜单选项。

对话框打开后，打开 Apearance and Behavior＆gt;系统设置＆gt; Android SDK ，然后选择第二个标签， SDK工具。

Answer 2

如果你想从命令行修复它（可能是像我的情况那样的自动构建服务器）：

echo y | android update sdk --no-ui --filter extra-android-m2repository --force --all
