Construction of the Android JNI development environment

In a few steps:

1. Installing Cygwin

2. Configure NDK Environment variables

3. Using the NDK to compile the program <---here Wakao becomes the *.so file, then the NDK development environment is well-equipped

4.

1. Installing Cygwin

Download Package Cygwin2.738.zip Http://dl8.cr173.com/soft1/cygwin2.738.zip

Note When installing cygwin2.738, note the point, reference: http://blog.csdn.net/zhangrongde/article/details/9372487

To check if the installation was successful: Cygcheck-c Cygwin

2. Configure NDK Environment variables

Reference: http://www.cnblogs.com/jdksummer/articles/2166057.html

First of all, my nkd directory, D:\ndkr10

Next, my Cygwin directory, D:\cygwin, contains a directory, cygdrive

Open cygwin\home\administrator\.bash_profile, add NDK variables,

ndk=/cygdrive/d/ndkr10

Export Ndkhome

Note: ndkhome name any

Open Cygwin, enter the CD $NDK, if the output

Indicates that the environment variable is set successfully.

3. Using the NDK to compile the program

Reference: http://www.cnblogs.com/jdksummer/articles/2166057.html

Open Cygwin, enter $NDK/ndk-build

Find compilation warning, check

To change the example teapot, make sure that the program under which you are compiling () Androidmanifest.xml has a version number greater than

<uses-SDK        android:minsdkversion="one"        android: Targetsdkversion=" />" ...

Enter $NDK/ndk-build, recompile, go to D:\ndkr10\samples\Teapot\libs\armeabi-v7a

Libteapotnativeactivity.so

Here, the NDK environment is well-equipped.
