android-自定义Luncher2

谷歌自带的Luncher2位于packages\apps\Launcher2，但是客户需要自定义Luncher2，在原Luncher2上修改总是不太好的。那么，最好就是自己定义的放在device/.../../custom_Luncher2/目录下，通过Android.mk控制使用自定义的Luncher2。

原packages\apps\Launcher2\Android.mk修改如下：

ifeq ($(BOARD_USE_DEFAULT_LAUNCHER2),true) LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE_TAGS := optional LOCAL_STATIC_JAVA_LIBRARIES := android-common LOCAL_SRC_FILES := $(call all-subdir-java-files) LOCAL_PACKAGE_NAME := Launcher2 LOCAL_CERTIFICATE := shared LOCAL_OVERRIDES_PACKAGES := Home LOCAL_PROGUARD_FLAGS := -include $(LOCAL_PATH)/proguard.flags include $(BUILD_PACKAGE) endif

在device/../../Boardconfig.mk中添加变量BOARD_USE_DEFAULT_LAUNCHER2 := false就OK了！在device/.../../custom_Luncher2/Android.mk中自然为ifeq ($(BOARD_USE_DEFAULT_LAUNCHER2),false)咯！
