(The figure is r5b version, do not need the first sentence, r5c version needs to define Android_ndk_root)
Now the setup work is complete and you can start debugging.
The debugging steps are:

strings provide a simple but limited way of maintaining the state some. can easily pass information from one page to another, But most browsers and client devices impose a 255-character Limi T on the length of the URL. In addition, the "query values are exposed to the" Internet via the URL so in some cases security may is an issue.
A URL with query strings could look like this:
Http://www.examples.com/list.aspx?categoryid=1productid=101
When List.aspx is being requested, the category and prod
The browser-based application framework is generally divided into two types:
Aplication Frameworks: Provides browser capabilities, but the most notable is the creation of a desktop GUI through a window generation component.
Infrastructural frameworks: Provides basic framework functionality and lightweight browser-side operations for developers to create specific applications, including:
Browser interaction based on the XMLHttpRequest component
XML
clients are affected (like the applicatin effect). In this case, the most likely need is a viewstate or session.
Application and Static variablesApplication is to save all objects through a collection.
Strong type:The object is preserved in the application and the cast action is required for its preservation and use. Boxunbox is more necessary for value types. has a greater impact on performance.The static variable is a strongly typed object.

HttpApplication is not responsible for these 19 pipeline events, only the 19 pipeline events are triggered at the right time.To From
