如何安装存储库com.android.support:appcompat-v7 [英] How to install Repository com.android.support:appcompat-v7

问题描述

我的gradle脚本中有一个错误:

在我的应用程序(等级)中，我有:

buildToolsVersion "25.0.2"

如何安装相应的appcompat库?尝试添加...时

compile 'com.android.support:appcompat-v7:25.0.2'

...我得到一个错误和以下图片:

单击链接时，没有任何反应. 有人可以指导我安装lib吗?

UPDATE 下面的屏幕截图显示，我显然安装了支持库，但是如何摆脱红线呢?那这个呢 ? 有时我会发生，当发布到Google Play时，缺少一些库.我在本地安装中无法识别此问题，但是在发布后，找不到许多报告类的用户.经过清理，重建和重新发布后，它可以正常工作.所以我喜欢一个干净的gradle脚本.

有人可以指导我，我如何摆脱这条红线.还是我们可以忽略它?

我也无法从以下位置启动SDK-Manager C:\ Users \ andreas \ AppData \ Local \ Android \ Sdk \ tools \ bin直接.

真的不可能解决这个问题吗?

解决方案

尝试一下:

1)工具-> android-> sdk管理器->启动独立SDK管理器

2)找到"extras-> Android支持存储库"并选中它(取消选中其他选项可加快安装速度)

3)单击安装

提示:如果android studio做一些奇怪的事情，也可以使用File-> Invalidate Caches/Restart.在某些情况下可能会有所帮助

更新:正如Gabriele Mariotti所提到的，它仅适用于现有库:)

更新2:似乎不推荐使用独立版本.您可以从设置窗口更新. Android Studio 2.3中的独立SDK Manager选项

另外，Gradle文件中的所有com.android.compat库都应具有相同的版本.最后一个是25.3.1

I have an error in my gradle script:

In my app (gradle) I have:

buildToolsVersion "25.0.2"

How can I install the corresponding appcompat lib ? When tryping to add ...

compile 'com.android.support:appcompat-v7:25.0.2'

... I get an error and the following picture :

When clicking on the link, nothing happens. Can someone guide me to install the lib ?

UPDATE Following screenshot shows, I obviously installed the support libraries, but then how can I get rid of the red line ? What about this ? I happens sometimes, that when publishing to google play, some libraries are missing. I can't recognize this in my local installation, but after publishing, lots of users reporting class not found. After cleaning and rebuilding and republishing it works. So I like to have a clean gradle script.

Can someone guide me , how I get rid of this red line. Or can we just ignore it ?

I am also not able to start SDK-Manager from C:\Users\andreas\AppData\Local\Android\Sdk\tools\bin directly.

Is it really not possible to solve this ?

解决方案

Try this:

1) tools -> android -> sdk manager -> Launch Standalone SDK Manager

2) find "extras -> Android support repository" and check it (uncheck other for faster installing)

3) click install

Tip: Also use File -> Invalidate Caches / Restart if android studio does something strange. It may help in some cases

Upd: As Gabriele Mariotti mentioned it only works for existing libraries :)

Upd 2: it seems that standalone version was deprecated. You can update from settings window. Standalone SDK Manager option in Android Studio 2.3

Also all com.android.compat libraries in the Gradle file should be with the same version. The last one is 25.3.1
