在需要保留的目录下，修改android.mk
在内容中添加
LOCAL_STRIP_MODULE :=false
那么编译对于的二进制文件Android.mk如下
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_CC := prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.7/bin/arm-linux-androideabi-gcc
LOCAL_CFLAGS := -g
LOCAL_CPPFLAGS := -g
LOCAL_MODULE := main
LOCAL_SRC_FILES := main.c
LOCAL_STRIP_MODULE :=false
LOCAL_MODULE_PATH := external/test
include $(BUILD_EXECUTABLE)
