android LOCAL_MODULE_TAGS 的一些说明

自己添加的app没有被编译进去，原因就是这个

 

"Set LOCAL_MODULE_TAGS to any number of whitespace-separatedtags.

This variable controls what build flavors the package getsincluded
in. For example:

    * user: include this inuser/userdebug builds
    * eng: include this in engbuilds
    * tests: the target is atesting target and makes it available for
tests
    * optional: don't includethis"

Are these the same as "variants" and if so, which name wouldaffect
the build and how? I've noticed that everything mentioned ina
product's makefile will always get built. But what gets in thefinal
system.img not always the same as what gets built.
