在Android Studio中安装哪些SDK平台工具？
[英]In Android Studio which SDK platform tools to install?
问题描述
My SDK Manager shows two platform tools, one which comes under the folder 'Tools' which has revision 22, and the other which comes under the folder 'Tools (Preview Channel)' which has revision 23rc2. 
我的SDK Manager显示了两个平台工具，一个位于“Tools”文件夹下，其中包含版本22，另一个位于“Tools（预览版频道）”文件夹下，其中包含版本23rc2。 When I download and install one, after rebooting the SDK Manager, the other one comes as not installed and vice-versa. 当我下载并安装一个，重新启动SDK Manager后，另一个未安装，反之亦然。
So if only one can be installed which one should I go for? 那么，如果只安装一个，我应该选择哪一个？

You can use only one version of SDK platform tool at a time. 您一次只能使用一个版本的SDK平台工具。
Under tools the Android SDK platform tools means those tools which have been fully developed by Google are are now stable builds. 在工具下，Android SDK平台工具意味着那些由Google完全开发的工具现在是稳定版本。
Under the preview channels are the one which are under development and are in beta stage, they are meant for advanced developers to give them an idea about the new releases and features yet to be offically released. 在预览渠道下，正处于开发阶段且处于测试阶段，它们适用于高级开发人员，让他们了解新版本和尚未正式发布的功能。
So, you must go with sdk tools under tools unless you are ready to take in account for those extra features and for some unknown bugs. 因此，您必须使用工具下的sdk工具，除非您已准备好考虑这些额外功能和一些未知错误。
