It's looking like the Android Support Library 19.1.0 is not available through the SDK Manager. How else might I obtain it?
看起来 Android 支持库 19.1.0 无法通过 SDK 管理器使用。我还能如何获得它？

So it turns out the library is in the following location
所以事实证明图书馆在以下位置
/android-sdk-macosx/extras/android/m2repository/com/android/support/support-v4/19.1.0
As opposed to the usual
与通常的相反
/android-sdk-macosx/extras/android/support
Also I had to restart eclipse and go to Android SDK Managerover and over and over, until the 19.1.0 version shows up.
我也不得不重新启动 eclipse 并Android SDK Manager一遍又一遍地重复，直到 19.1.0 版本出现。
I hope this saves someone else some trouble.
我希望这可以为其他人省去一些麻烦。

It was difficult to update the support library to version 19.1 so i downloaded it manually from https://dl-ssl.google.com/android/repository/support_r19.1.zipand added the jar to my build path manually. works for me. I dont know why the 19 update shows instead of 19.1.0
将支持库更新到版本 19.1 很困难，所以我从https://dl-ssl.google.com/android/repository/support_r19.1.zip手动下载它并手动将 jar 添加到我的构建路径中。对我来说有效。我不知道为什么显示 19 更新而不是 19.1.0

The SDK Manager update Android Support Library to 19.1.0. But when you use Android Tools > Add Support Library, eclipse update Android Support Library to 19.0. I think this is a bug. Copy Android Support Library 19.1.0 to libs folder manually.
SDK 管理器将 Android 支持库更新到 19.1.0。但是当您使用 Android Tools > Add Support Library 时，eclipse 会将 Android Support Library 更新为 19.0。我认为这是一个错误。手动将 Android Support Library 19.1.0 复制到 libs 文件夹。

It looks as if you don't have the android-support-v4.jar in Java Build Path. Add it from the android-support-v7-appcompat.
看起来您在 Java Build Path 中没有 android-support- v4.jar。从 android-support-v7-appcompat 添加它。

For some reason, even though you may include v4 support libraryor you may have v7-appcompatincluded in your project, you may not be able to import SwipeRefreshLayout.
出于某种原因，即使您可能包含v4 support library或可能已经v7-appcompat包含在您的项目中，您也可能无法导入SwipeRefreshLayout.
You need to make sure that
你需要确保
- you change the
target=android-19totarget=android-22(It should be anything greater that 19) and - manually import :
import android.support.v4.widget.SwipeRefreshLayout;in your activity which will resolve the import related issue.
- 您将更
target=android-19改为target=android-22（应该是大于 19 的任何值）和 - 手动导入：
import android.support.v4.widget.SwipeRefreshLayout;在您的活动中，这将解决与导入相关的问题。

Just update it by starting Android SDK manager manually and add new v4 lib to your project.
只需通过手动启动 Android SDK 管理器来更新它，并将新的 v4 库添加到您的项目中。
