And, while the Android Developers Guide provides a solution, it’s a bit cumbersome and complex. So, many web developers often turn to tools like Firefox’s Firebug or Webkit’s Web Inspector because they are easy to use, powerful, and convenient. However, what developers often find when using these tools is that the end result is quite different on the actual device. We decided to create our own solution — a tool based on the standard solution proposed by the Android team, but much simpler to use. We call it RemoteJS, a tool that enables you to debug your JavaScript code while running on an Android device or emulator from your workstation. Build RemoteJS 构建 RemoteJS 程序是一个相当直截了当的过程。首先请确认您已安装了 Qt 框架。然后在Sencha 实验室源码库全新的“Android 工具”那里下载我们 RemoteJS 源代码。构建桌面应用程序如下 Building the application is a fairly straight forward process. First, confirm that you haveQt framework installed. Then, download the RemoteJS source code from our brand new Android Tools repository on Sencha Labs.Build the desktop application as follows: [plain] view plaincopy git clone git://github.com/senchalabs/android-tools.git cd android-tools/remotejs/src/desktop qmake make 接着需要做的的就是安装 Android SDK将设备联入计算机或启动你的模拟器。下面的截图是位于模拟器旁边一个的 RemoteJS 工具用来检测来自Sencha Touch 的例子 Next, all you need to do is install the Android SDK, plug your device in (or launch your emulator), and you’re ready to go. Here’s a screenshot of the RemoteJS tool running next to an emulator, inspecting anexample from Sencha Touch: 该程序会自动安装一个包包的名字与设备上的名称相同。这个工具实际上是代替 Android 浏览器的网页加载器。由于两款程序都是使用同一款的 Web 浏览器引擎所以从程序员角度看不需要顾忌那些一致性的担心。用于正是这两个应用程序相同。欲了解工作原理及实施细则请参阅自述文件。只需在控制台上输入 URL 就可以打开网址。如果你输入不包括开头的协议就默认是“www”的。如果你连接超过一个以上的设备您将会在一个列表中作出选择。同样当您断开连接的设备时它会侦测这一事件然后它会回落到刚才唯一连接着的设备。然后等待直到你再次连接下一个设备。请注意要输出一些内容你需要使用console.log。 The program automatically installs a package with the same name on the device. This tool will actually be the one loading your page, instead of the Android browser. This doesn’t represent any concern from the developer’s perspective, since the web engine component that is used is exactly the same on both applications. For further details on how it works and the implementation details, please refer to theREADME. To open a specific URL, just enter it on the console. If you don’t include the protocol, only addresses starting with “www” will be validated. If you have more than one attached device, you’ll be presented with a list to choose from. Similarly, it will detect when you disconnect the device already being used. It will then fall back to the only attached device left, if that’s the case, or wait until you connect one again. Please note that in order to actually get some output back, you need to make use of console.log. 编写远程调试的脚本 Scriptable Remote Debugging 我们认为既然 GUI 版本的工作那么好于是我们可以写类似而且无缝的东西。主要目标是充分利用 Python 中已选择实现的语言自动化页回归测试。为此写一个Android 调试桥Android Debug BridgeADB的 Python 模块便可以非常灵活地从您的主机上写脚本。自然一个 RemoteJS 外壳版本也写在 adb 模块的顶部。它侦听 stdin 输入的 JavaScript 命令然后输出结果到 stdout。这里马上就有一个例子调试另一个Sencha Touch 的例子 We thought that since the GUI version worked so well, we could write something similar that would run headlessly. The main goal was to automate page regression tests, taking full advantage of Python, the chosen implementation language. For that, anAndroid Debug Bridge (adb)Python module was written, which allows for very flexible scripting from your host. Naturally, a shell version of RemoteJS was also written on top of the adb module. It listens for JavaScript commands on stdin and output results to stdout. Here’s the tool in action, debugging another Sencha Touch example: 未来 Coming Up 源代码不断在变化我们计划为这些工具注入更多的功能。欢迎你以任何方式参与贡献。adb Python模块将有可能远程自动注射设备上记录的事件并可在任何时候进行截图。这将使线性的自动检查一致性成为可能。所以敬请关注并不妨 clone 我们公共库上的Android 工具包然后亲自试一试。所有可用都遵循 MIT 许可。 The source code is changing constantly, and we plan to extend the capabilities of these tools. You’re more than welcome to contribute in any way. With the adb Python module, it will be possible to remotely automate the injection of recorded events on the device and grab screenshots at any point. This will allow automated verification of behavior consistency along time. Stay tuned and please feel free to clone our android-tools public repository to play around with the tools and code.
