上次提到AndroidStudio2.2進行NDK開發超方便的配置方式，不用進行Android.mk 配置，也不用進行Application.mk配置，只要配置CMakeList即可。那麼問題來了，通過該方式生成的配置檔案預設是隻native-lib.cpp一個cpp檔案的，那麼怎麼配置編譯多個.cpp檔案呢？

以之前釋出的

NDK下獲取IEIM並且使用MD5演算法加密

為例，我們另外需要MD5.cpp和IEIM.cpp,   將工程在AndroidStudio2.2中編寫好後，編譯，(⊙o⊙)哦！

密集恐懼症要來了，  忍住，一定要忍住。。。。

這個錯是啥意思   仔細分析  其實就是找不到MD5.cpp和IEIM.cpp中的方法啦。

怎麼解決呢？

Module下有一個CMakeLists.txt   的檔案  預設內容是這樣的，（只貼了需要改動的部分）

cmake_minimum_required(VERSION 3.4.1)

# Creates and names a library, sets it as either STATIC

# or SHARED, and provides the relative paths to its source code.

# You can define multiple libraries, and CMake builds it for you.

# Gradle automatically packages shared libraries with your APK.

add_library( # Sets the name of the library.

native-lib

# Sets the library as a shared library.

SHARED

# Provides a relative path to your source file(s).

# Associated headers in the same location as their source

# file are automatically included.

src/main/cpp/native-lib.cpp )

改為

cmake_minimum_required(VERSION 3.4.1)

# Creates and names a library, sets it as either STATIC

# or SHARED, and provides the relative paths to its source code.

# You can define multiple libraries, and CMake builds it for you.

# Gradle automatically packages shared libraries with your APK.

file(GLOB native_srcs "src/main/cpp/*.cpp")

add_library( # Sets the name of the library.

native-lib

# Sets the library as a shared library.

SHARED

# Provides a relative path to your source file(s).

# Associated headers in the same location as their source

# file are automatically included.

${native_srcs})

哈哈，大功告成！再多個cpp都不成問題啦！快去動手試試吧
