How to build Module for Platform
- It is only for modules are needed to using Android build system.
- Please check its own install information under its folder for other module.

[Step to build]
1. Get android open source.
    : version info - Android 4.2.2
    ( Download site : http://source.android.com )

2. Copy module that you want to build - to original android open source
   If same module exist in android open source, you should replace it. (no overwrite)

  # It is possible to build all modules at once.

3. In case of 'vendor/broadcom/common/apps/audio/alsaplugin',
              'android/device/samsung/bcm_common/alsa-lib'

   you should add following text in 'build\target\board\generic\BoardConfig.mk'

   BOARD_USES_ALSA_AUDIO := true
   OPENSOURCE_ALSA_AUDIO : true
   BRCM_ALSA_LIB_DIR=device/samsung/bcm_common/alsa-lib

4. You should add module name to 'PRODUCT_PACKAGES' in 'build\target\product\core.mk' as following case.
	case 1) e2fsprog : should add 'e2fsck' to PRODUCT_PACKAGES
	case 2) libexifa : should add 'libexifa' to PRODUCT_PACKAGES
	case 3) libjpega : should add 'libjpega' to PRODUCT_PACKAGES
	case 4) KeyUtils : should add 'libkeyutils' to PRODUCT_PACKAGES
	case 5) libasound : should add 'libasound' to PRODUCT_PACKAGES
	case 6) audio\alsaplugin : should add 'libasound_module_pcm_bcmfilter' to PRODUCT_PACKAGES

ex.) [build\target\product\core.mk] - add all module name for case 1 ~ 6 at once
PRODUCT_PACKAGES += \
	e2fsck \
	libexifa \
	libjpega \
	libkeyutils \
	libasound \
	libasound_module_pcm_bcmfilter

5. excute build command
   ./build.sh user
