一、创建google doc form，用于保存错误报告；
1.https://drive.google.com/?authuser=0#my-drive 登录账户；
2.在#my-drive 创建spreadsheets和form并不能拿到formkey，在此提供一个链接方便大家去创建一个可用的form；
https://docs.google.com/spreadsheet/viewform?formkey=dGdTZEFieDRncHZwT3hpWk9icjloeHc6MQ
点击该链接，在弹出的网页中点击submit，成功后在在返回的界面上点击Create my own form
3. 获取formkey，在新建的form页面中点击菜单中的form，选择Embed from in a webpage...,在弹出的窗口中即可拿到formkey
二、https://github.com/ACRA/acra 下载源码 acra-4.5.0RC2
省略拿formkey的步骤，按照https://github.com/ACRA/acra/wiki/BasicSetup配置基本可以集成好可以使用的环境
三、集成后，运行会出现一些错误，在此罗列一下如何修改；
1.发送不成功，出现invalid set cookie attribute；
解决方法：修改文件，HttpRequest 152行增加以下两行
httpClient.getParams().setParameter("http.protocol.single-cookie-header",true);
HttpClientParams.setCookiePolicy( httpClient.getParams(), CookiePolicy.BROWSER_COMPATIBILITY);
response = httpClient.execute(httpRequest, new BasicHttpContext());
2.发送成功，google 服务器会返回如下信息

3.如果出现form表单中显示的数据项不正确，没有显示，或者显示的位置不对
解决方法：详见http://blog.dfarooq.com/2012/10/using-google-spreadsheets-as-database.html
要保证form表单源码中定义的输入框id 类似entry.2.single，要和acra-4.5.0RC2源码中保持一致；
