Build the Android NDK environment the Windows XP environment1 Some Downloads

① NDK r7:http://developer.android.com/sdk/ndk/index.html
② cygwin:http://www.cygwin.com/(1.7.11-1)
③ notepad++:http://notepad-plus-plus.org/download/v5.9.8.html

2 Cygwin installation

① perform the downloaded setup.exe. Click Next
② Select the installation method. Select Online installation. Suppose there is an off-the-shelf package. Option to install offline
③ Select the installation folder (Cygwin finally install folder)
④ Setting the local package staging path (download file storage folder)
⑤ Setting the network connection mode: Default direct connection
⑥ Select Download website. It's faster than http://mirrors.163.com.
⑦ Select the installation item.

By default, just select Devel (click Devel in the list, change the default to install), and the others are the defaults.
Note: binutils, gcc, Gcc-mingw, GDB, make and so on must be installed. See Refs-5
⑧ long wait until download is complete
Note: After downloading the package can be backed up, so that in the future can be directly offline installation, Fast Oh!

⑨ adds environment variables (System Properties, environment variables->path) to the system, such as my c:/cygwin/bin

3 Cygwin environmental validation

① executes Cygwin once (Cygwin.bat). To create some user environment files
② Detection
Version number of Cygwin: Cygcheck-c Cygwin
GCC version number: gcc--version
Version number of g++: g++--version
Make's version number: Make--version
GDB version number: GDB--version
The results are for example:

4 Configuring the NDK Path

① Extract the downloaded NDK to a folder
② Zai Cygwin home\< your username>\.bash_profile file last added: (Available notepad++ or ultraedit open)
ndk=/cygdrive/< your drive symbol >/<android NDK folder > Export NDK,
As my NDK=/CYGDRIVE/C/ANDROID/ANDROID-NDK-R7 export NDK
Note: The name "NDK" is a random one, and it is often used for a long time.
② Verification
Restart Cygwin, enter: CD $NDK
can enter the NDK corresponding folder description settings OK.

5 compiling project build. So file

Way One:
Compile under the Cygwin command line, as seen in the compile step. Three-step

① into Android Project working folder: CD $NDK
② into the Samples\hello-jni folder, the full path is C:\Android\android-ndk-r7\samples\hello-jni
③ Execution: $NDK/ndk-build.
Note: the command $NDK and/ndk-build are connected together with no spaces in between. The actual use is to enter the complete $ndk/ndk-build, do not just play ndk-build

Way two:
① in the. bash_profile file mentioned in step 4. Add to Jni=/cygdrive/jni folder
As I can for Jni=/cygdrive/c/android/android-ndk-r7/samples/hello-jni.
② CD $NDK
③ CD $jni

Two files are generated after normal compilation. For example, generate the appropriate. So file under the Project Libs/armeabi folder.
