$(info string)$(warning string)$(error string)

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := libappblog
LOCAL_CFLAGS := -Werror
LOCAL_SRC_FILES := appblog.cpp
LOCAL_LDLIBS := -llog -lGLESv2
$(warning 'www.appblog.cn')
$(warning $(LOCAL_SRC_FILES),$(LOCAL_PATH))
$(warning $(all-subdir-makefiles),$(this.makefile))
$(warning $(TARGET_ARCH))
$(info erroinfo,test)
$(message msg)
$(warning "LOCAL_LDLIBS = $(LOCAL_LDLIBS)")
$(info $(TARGET_PLATFORM))
