LOCAL_MODULE_TAGS ：=user eng tests optional

user: 指該模組只在user版本下才編譯

eng: 指該模組只在eng版本下才編譯

tests: 指該模組只在tests版本下才編譯

optional:指該模組在所有版本下都編譯

 

如果兩次make之間選了不同的編譯模式，則需要運行一下make installclean，確保本次make不會用到上次install的檔案，也可以運行make clean，不過耗時較長。

 

eng This is the default flavor. A plain "make" is the same as "make eng". droid is an alias for eng. 
  * Installs modules tagged with: eng, debug, user, and/or development. 
  * Installs non-APK modules that have no tags specified. 
  * Installs APKs according to the product definition files, in addition to tagged APKs. 
  * ro.secure=0 
  * ro.debuggable=1 
  * ro.kernel.android.checkjni=1 
  * adb is enabled by default.   

user "make user"     This is the flavor intended to be the final release bits. 
  * Installs modules tagged with user. 
  * Installs non-APK modules that have no tags specified. 
  * Installs APKs according to the product definition files; tags are ignored for APK modules. 
  * ro.secure=1 
  * ro.debuggable=0 
  * adb is disabled by default.   

userdebug "make userdebug"     The same as user, except: 
  * Also installs modules tagged with debug. 
  * ro.debuggable=1 
  * adb is enabled by default.

 

Build flavors/types

When building for a particular product, it‘s often useful to have minor variations on what is ultimately the final release build. These are the currently-defined "flavors" or "types" (we need to settle on a real name for these).

eng	This is the default flavor. A plain "make " is the same as "make eng ". droid is an alias for eng . Installs modules tagged with: eng , debug , user , and/or development . Installs non-APK modules that have no tags specified. Installs APKs according to the product definition files, in addition to tagged APKs. ro.secure=0 ro.debuggable=1 ro.kernel.android.checkjni=1 adb is enabled by default.
user	"make user " This is the flavor intended to be the final release bits. Installs modules tagged with user . Installs non-APK modules that have no tags specified. Installs APKs according to the product definition files; tags are ignored for APK modules. ro.secure=1 ro.debuggable=0 adb is disabled by default.
userdebug	"make userdebug " The same as user , except: Also installs modules tagged with debug . ro.debuggable=1 adb is enabled by default.

If you build one flavor and then want to build another, you should run "make installclean " between the two makes to guarantee that you don‘t pick up files installed by the previous flavor. "make clean " will also suffice, but it takes a lot longer.
