原始碼開發經常需要把eclipse專案(雖然已經不使用此工具開發app了)或studio專案放到原始碼裡面，下面寫下自己的經驗以備查閱

1，studio專案，需要保留的檔案，如下圖：mk檔案自己寫的

2，mk檔案

# Copyright 2007-2008 The Android Open Source Project

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, app/src/main/java)
LOCAL_MANIFEST_FILE := app/src/main/AndroidManifest.xml
LOCAL_RESOURCE_DIR := $(LOCAL_PATH)/app/src/main/res

    


LOCAL_PACKAGE_NAME := DMCompaus

LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)



# This finds and builds the test apk as well, so a single make does both.
include $(call all-makefiles-under,$(LOCAL_PATH))
 
 

其中  LOCAL_SRC_FILES：表示程式碼的位置

        LOCAL_MANIFEST_FILE：AndroidManifest.xml路徑

        LOCAL_RESOURCE_DIR：res資源路徑

下面是eclipse專案

2，mk檔案

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_PACKAGE_NAME := FlashLight

LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)

# This finds and builds the test apk as well, so a single make does both.
include $(call all-makefiles-under,$(LOCAL_PATH))
 

LOCAL_PACKAGE_NAME := FlashLight這個名字是編譯進系統時，device.mk寫的名字
