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

Build flavors/types

When building for a particular product, it's often useful to have minorvariations on what is ultimately the final release build. These are thecurrently-defined "flavors" or "types" (we need to settle on a real namefor 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 thatyou don't pick up files installed by the previous flavor. "makeclean" will also suffice, but it takes a lot longer.
