1. Root directory:
src directory ---Storing source code files
gen directory ----the file generated by ADT plug-in (automatically generated)
assets directory---storage resource file directory, no ID is generated in it
res directory---stores the resource file directory. Each file or value here will generate an ID (variable) in it.
---The entire application configuration file, store some package name, version number, program icon, program tag
---Check the version file, automatically generated, cannot be modified (modification will be deleted).
2. Key directories and files
res/drawable-xxxx is the directory where pictures are stored. Each picture needs to be prepared with three resolution versions. drawable-hdpi---store high resolution version drawable-ldpi--store medium resolution version drawable-mdpi--store low resolution version
res/layout directory ----place layout file (xml file), each activity corresponds to an XML file
document
drawable class---Id for the image production layout class---Id for the layout file
string class---Id generated for the key-value pairs inside File
Controls the position of the controls in the Activity, and each Activity corresponds to a layout file
Store key-value pairs, which are generally used to switch multilingual versions of the program (multiple files, same keys, different values)
