Android(安卓)build target list.

Android build target list.

make sdk - build the tools that are part of an SDK (adb, fastboot, etc.)
make snod - build the system image from the current software binaries
make services
make runtime
make droid - make droid is the normal build.
make all - make everything, whether it is included in the product definition or not
make clean - remove all built files (prepare for a new build). Same as rm -rf out/<configuration>/
make modules - shows a list of submodules that can be built (List of all LOCAL_MODULE definitions)
make <local_module> - make a specific module (note that this is not the same as directory name. It is the LOCAL_MODULE definition in the Android.mk file)
make clean-<local_module> - clean a specific module

Build Variants

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 build variants:

eng

This is the default flavor. A plain make is the same as make 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 runmake 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.
