我安装了新的 ADT:http://developer.android.com/sdk/index.html?hl=sk 然后我安装了:

当我进入 Eclipse 自述文件目录时，有:

Eclipse Project Release Notes

Release 4.3.0 Last revised May 29th, 2013

我创建了新的 Android 应用程序，然后右键单击它->Google->生成 Google App Engine 后端，这就是我得到的:

如何处理？ 编辑:

最佳答案

我在下面进行了尝试，它有所帮助。

  1. 勾选名为 Use default compliance settings 的复选框，如下图突出显示的部分(蓝色)。
  2. 如果这没有帮助，请尝试将 Compiler compliance level 更改为不同的级别，按应用然后再返回。

  1. ruby - 使用 RubyZip 生成 ZIP 文件时设置压缩级别 - 2

    我有一个Ruby程序，它使用rubyzip压缩XML文件的目录树。gem。我的问题是文件开始变得很重，我想提高压缩级别，因为压缩时间不是问题。我在rubyzipdocumentation中找不到一种为创建的ZIP文件指定压缩级别的方法。有人知道如何更改此设置吗？是否有另一个允许指定压缩级别的Ruby库？ 最佳答案 这是我通过查看ruby​​zip内部创建的代码。level=Zlib::BEST_COMPRESSIONZip::ZipOutputStream.open(zip_file)do|zip|Dir.glob("**/*")d

  2. ruby-on-rails - Rails 常用字符串(用于通知和错误信息等) - 2

    大约一年前，我决定确保每个包含非唯一文本的Flash通知都将从模块中的方法中获取文本。我这样做的最初原因是为了避免一遍又一遍地输入相同的字符串。如果我想更改措辞，我可以在一个地方轻松完成，而且一遍又一遍地重复同一件事而出现拼写错误的可能性也会降低。我最终得到的是这样的:moduleMessagesdefformat_error_messages(errors)errors.map{|attribute,message|"Error:#{attribute.to_s.titleize}#{message}."}enddeferror_message_could_not_find(obje

  4. ruby - 如何使用 Ruby aws/s3 Gem 生成安全 URL 以从 s3 下载文件 - 2

    我正在编写一个小脚本来定位aws存储桶中的特定文件，并创建一个临时验证的url以发送给同事。(理想情况下，这将创建类似于在控制台上右键单击存储桶中的文件并复制链接地址的结果)。我研究过回形针，它似乎不符合这个标准，但我可能只是不知道它的全部功能。我尝试了以下方法:defauthenticated_url(file_name,bucket)AWS::S3::S3Object.url_for(file_name,bucket,:secure=>true,:expires=>20*60)end产生这种类型的结果:...-1.amazonaws.com/file_path/file.zip.A

  6. Ruby Sinatra 配置用于生产和开发 - 2

    我已经在Sinatra上创建了应用程序，它代表了一个简单的API。我想在生产和开发上进行部署。我想在部署时选择，是开发还是生产，一些方法的逻辑应该改变，这取决于部署类型。是否有任何想法，如何完成以及解决此问题的一些示例。例子:我有代码get'/api/test'doreturn"Itisdev"end但是在部署到生产环境之后我想在运行/api/test之后看到ItisPROD如何实现？ 最佳答案 根据SinatraDocumentation:EnvironmentscanbesetthroughtheRACK_ENVenvironm

  7. ruby-on-rails - Ruby on Rails - 为文本区域和图片生成列 - 2

    我是Rails的新手，所以请原谅简单的问题。我正在为一家公司创建一个网站。那家公司想在网站上展示它的客户。我想让客户自己管理这个。我正在为“客户”生成一个表格，我想要的三列是:公司名称、公司描述和Logo。对于名称，我使用的是name:string但不确定如何在脚本/生成脚手架终端命令中最好地创建描述列(因为我打算将其设置为文本区域)和图片。我怀疑描述(我想成为一个文本区域)应该仍然是描述:字符串，然后以实际形式进行调整。不确定如何处理图片字段。那么……说来话长:我在脚手架命令中输入什么来生成描述和图片列？ 最佳答案 对于“文本”数

  8. java - 从 JRuby 调用 Java 类的问题 - 2

    我正在尝试使用boilerpipe来自JRuby。我看过guide从JRuby调用Java，并成功地将它与另一个Java包一起使用，但无法弄清楚为什么同样的东西不能用于boilerpipe。我正在尝试基本上从JRuby中执行与此Java等效的操作:URLurl=newURL("http://www.example.com/some-location/index.html");Stringtext=ArticleExtractor.INSTANCE.getText(url);在JRuby中试过这个:require'java'url=java.net.URL.new("http://www

  10. ruby - inverse_of 是否适用于 has_many？ - 2

    当我使用has_one时，它​​工作得很好，但在has_many上却不行。在这里您可以看到object_id不同，因为它运行了另一个SQL来再次获取它。ruby-1.9.2-p290:001>e=Employee.create(name:'rafael',active:false)ruby-1.9.2-p290:002>b=Badge.create(number:1,employee:e)ruby-1.9.2-p290:003>a=Address.create(street:"123MarketSt",city:"SanDiego",employee:e)ruby-1.9.2-p290
