# [Android external 目录下新增一个可执行应用及编译](https://blog.csdn.net/loongembedded/article/details/76538470)
新增的应用为 test 文件夹,此文件夹下包含 Android.mk 和 test.cpp 文件Android.mk 内容如下:
```sh
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := study.cpp
LOCAL_MODULE := study
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_PATH := $(TARGET_OUT_EXECUTABLES)
include $(BUILD_EXECUTABLE)
```
TARGET_OUT_EXECUTABLES 对应 out 目录下的,比如 out\target\product\msm8937_64\system\bin
截止上面的修改,用 mmm external/study 可以编译生成 study 可执行文件到 out\target\product\msm8937_64\system\bin但是整个系统编译的时候不会生成。为了在在整个系统编译的时候(比如make -j16)能够生成,还需要修改 device\qcom\common\base.mk增加
PRODUCT_PACKAGES += study
