我正在尝试为 API 7 及更高版本实现 Action Bar。
我正在使用 Android Studio 创建一个具有以下配置的新简单项目:
- 最低 SDK:API 7
- 目标 SDK:API 14
- 编译:Google APIs 14
- 主题:带深色操作栏的全息灯
- 设置Create Activity、Fragments、Navigation Drawer、Action Bar
然后在下一个屏幕中我选择空白 Activity
在最后一个屏幕上，我选择 Navigation Drawer 以获得其他功能。
我使用 API 14 在模拟器上运行应用程序，一切正常。
但是当我在带有 API 7 的模拟器上运行它时(也在真实设备上)，当我按下菜单按钮时它崩溃了。
经过一些实验，我发现只有在操作栏中有溢出操作时才会发生这种情况。
我错过了什么？
所有代码均由 Android Studio 自动生成(出于测试目的进行了一些小修改)

您没有提及您运行的是什么版本的 Android Studio 或什么版本的 Android Gradle 插件，但我猜它分别是 0.5.1 和 0.9.1。如果这是真的，那么您遇到了错误 https://code.google.com/p/android/issues/detail?id=67376 ，即 0.9.1 中的 PNG 处理代码生成的 PNG 导致 Gingerbread 崩溃，原因仍在调查中。从该错误的评论 #10 中，您可以选择以下两种解决方法之一:
just add next lines to your build.gradle in order to use 0.9.1 plugin or just downgrade to 0.9.0
// Use old PNG cruncher because of crashes on GB android.aaptOptions.useAaptPngCruncher = true
如果您没有运行 0.9.1 版的 Android Gradle 插件，那么这不是您的错误。

我构建了两个需要相互通信和发送文件的Rails应用程序。例如，一个Rails应用程序会发送请求以查看其他应用程序数据库中的表。然后另一个应用程序将呈现该表的json并将其发回。我还希望一个应用程序将存储在其公共(public)目录中的文本文件发送到另一个应用程序的公共(public)目录。我从来没有做过这样的事情，所以我什至不知道从哪里开始。任何帮助，将不胜感激。谢谢! 最佳答案 无论Rails是什么，几乎所有Web应用程序都有您的要求，大多数现代Web应用程序都需要相互通信。但是有一个小小的理解需要你坚持下去，网站不应直接访问彼此
