在哪里可以找到Android的＆QUOT; Fingerpaint＆QUOT;演示？ （机器人工作室时代） [英] WHERE to find Android "Fingerpaint" demo? (Android Studio era)
问题描述
很多很多Android的讨论集中在（显然，著名）Fingerpaint示例：
Many, many Android discussions focus on the (apparently, famous) Fingerpaint sample:
http://stackoverflow.com/a/16650524/294884
我在哪里可以得到它，与Android Studio来使用？ .. 2014年
http://developer.android.com/samples/index.html
或者是它现在只是完全过时和遗产？感谢您的任何信息
Or is it now just completely out of date and legacy? Thanks for any info
Android的工作室：它有没有文件夹，采样/或类似............
Android Studio: it has NO folders, samples/ or the like............
还有一种可能性心爱的SDK管理器，在Mac上 - 工作室，可以帮助
There's a possibility the beloved SDK Manager, on Mac - Studio, could help?
请问我得去与API11文件夹？
Would I have to go with the API11 folder?
Android的页面似乎并没有表现出Fingerpaint：这里是我所看到的
The Android page does not seem to show Fingerpaint: here's what I see
寻找在每个类别中，没有Fingerpaint ....
Looking in each category, there is no Fingerpaint....
在Mac上，我还是设法下载使用心爱的ADKManager API11样品。 Incerdibly，在Mac上，他们都深深地藏在包内（螺丝的Mac！）但是，样品是不存在的......悲伤
On a Mac, I did manage to download API11 Samples using the beloved ADKManager. Incerdibly, on Mac they are deeply hidden inside a package (screw Macs!) But that "sample" is not there...sad
推荐答案
我找到了！由于魔像和Raghunandan
I found it! Thanks to Golem and Raghunandan
这是令人难以置信很难找到它在Mac上。使用SDKManager下载API11Samples。
It is incredibly hard to find it on a Mac. Use SDKManager to download API11Samples.
接下来，您必须在Mac包装内容的工作室应用程序本身，
Next you have to on a Mac "package contents" the Studio app itself,
和钻一路下跌。试试ApiDemos
and drill way down. try "ApiDemos"
我根本不知道这是该文件的最新版本。
I simply don't know if this is the latest version of the file.
对于任何Mac用户，为您节省时间：
for any Mac users, to save you time:
据我所知，这是最新的版本。另请参阅在 http://stackoverflow.com/a/16650524/294884
As far as I know this is the latest version. Please also see the outstanding discussion at http://stackoverflow.com/a/16650524/294884
整个文件Fingerpaint.java：（据我所知这是整个样本：）
the entire file Fingerpaint.java: (as far as I know that is the whole sample:)
这是从SDK11，17或19：
THIS IS FROM SDK11, 17 or 19:
我仔细检查，该文件是相同的11,17,19。希望它可以帮助别人。
I CAREFULLY CHECKED AND THE FILE IS IDENTICAL in 11,17,19. Hope it helps someone.
