Android Rapid Development appbase--(4). Detailed Com.snicesoft.Application and baseactivity

In the appbase--of Android Rapid Development (1). AppBase used Com.snicesoft.Application and baseactivity in the introduction, and this article unlocks their veil.

• List and related methods are the methods used to manage activity in a common app
• Exitapp () is the real way to quit the app, only to have all of the activity completed and the process of killing the app to actually quit an app.
• Httpreq, Bitmaputils, Dbutils, httputils all configured at the time of the application, and provide the corresponding method to obtain, the purpose is to allow the entire app to keep only one object, waste of resources, Any location where the application can be obtained can be manipulated with the corresponding module unique object.
• Hu (): Return Httputils Object
• BU (): Returns the Bitmaputils object
• Httpreq (): Returns the Httpreq object
• Du (String dbName): Returns the Dbutils object based on the database name, providing multi-data support.

2) How to expand

• You can inherit com.snicesoft.Application to implement your own application (recommended)
• can also completely imitate com.snicesoft.Application own realization application

Com.snicesoft.Application in the earliest time used the static method, because the static reference to the object is not properly controlled, will cause a lot of problems, and then all changed.

• Baseactivity avfragmentactivity in expansion sub-avlib

2) How to expand

• Inherit baseactivity rewrite your baseactivity and add your own app's generic business (recommended)
• Inheriting the underlying activity in Avlib
