LOCAL_MODULE_PATH

LOCAL_MODULE_PATH 表示模块生成的目标将最终存放的目录，也即目标的安装路径。

LOCAL_MODULE_CLASS用于制定LOCAL_MODULE_PATH的路径所在。

如果在Android.mk没有直接明确LOCAL_MODULE_PATH 的话，需要通过以下规则来自动生成base_rules.mk：

LOCAL_MODULE_PATH := (strip(LOCAL_MODULE_PATH))
ifeq ((LOCAL_MODULE_PATH),)
        #LOCAL_MODULE_CLASS :=
  LOCAL_MODULE_PATH :=((my_prefix)OUT(partition_tag)_(LOCAL_MODULE_CLASS))(info *******//(LOCAL_MODULE_PATH))
ifeq ((strip (LOCAL_MODULE_PATH)),)(error (LOCAL_PATH): unhandled LOCAL_MODULE_CLASS "(LOCAL_MODULE_CLASS)")
  endif
endif

在不同的Android.mk文件中，对于模块include()不同的编译类型选项，比如对于Library或者app,execut等在调用对应的处理mk文件时，会默认就指定当前的LOCAL_MODULE_CLASS的值，比如EXECUTABLES、SHARED_LIBRARIES等。所以在自己编写的Android.mk可不显示的指定LOCAL_MODULE_CLASS的值。
但当遇到 include $(BUILD_PREBUILT) 的预编译选项时不会指定模块模块编译输出的类型CLASS，需要在自己编写的Android.mk中明确指定LOCAL_MODULE_CLASS的值如ETC/APP等，使其值为非空，从而帮助系统确定LOCAL_MODULE_PATH的路径，比如最终编译输出 LOCAL_MODULE_PATH := $(TARGRT_OUT_ETC)。
