ADT+NDK+OPENCV Environment Deployment

ADT+NDK+OPENCV Environment Deployment

Recently in the study of OpenCV image processing, here to introduce the ADT+NDK+OPENCV environment deployment and simple implementation of a picture of grayscale processing

Development tools

• ADT (Adt-bundle-windows)
• NDK (android-ndk-r9d)
• OpenCV (OPENCV-2.4.10-ANDROID-SDK)

Because of the ADT+NDK environment deployment described earlier, only OpenCV is described here

• Jdk+adt Environment Deployment

Environment variables

Note: All development tools for this machine are placed in the D:\DevTools directory

• Java_home D:\DevTools\Java\jdk1.8.0_05
• Path.; %java_home%\bin;%java_home%\jre\bin;d:\devtools\adt-bundle-windows\sdk\tools;d:\devtools\adt-bundle-windows\ Sdk\platform-tools;
• CLASSPATH.; %java_home%\lib\tools.jar;%java_home%\lib\dt.jar;%java_home%\bin;

First, OpenCV download and configuration

1.:http://sourceforge.net/projects/opencvlibrary/files/opencv-android/

　　

It is recommended to use the 2.4.10 version, click on the version number to download, or click here to download http://jaist.dl.sourceforge.net/project/opencvlibrary/opencv-android/2.4.10 /opencv-2.4.10-android-sdk.zip

2. After downloading, unzip the package to the development directory.

　　

II. implementation of OPENCV development needs to configure the NDK's development environment locally

1. Download Ndk:http://developer.android.com/intl/zh-cn/tools/sdk/ndk/index.html#downloads

　　

2. After downloading, unzip the package to the development directory.

　　

Third, eclipse internal parameter configuration

1.WINDOW--PREFERENCES--ANDROID--SDK location >>d:\devtools\adt-bundle-windows\sdk--apply--ok

2.WINDOW--PREFERENCES--ANDROID--NDK--NDK location >>d:\devtools\android-ndk-r9d--apply--ok

3.window--preferences--c/c++--build--environment, add an environment variable: variable name: Ndkroot variable Value: D:\DevTools\android-ndk-r9d--Apply-- Ok

3. Right click on Project name--properties--android >> Select Android Editor version at Project Build Target

4. Right-click the project name--properties--android >> Select OpenCV Library at the library--add--

　　

5. Right click on project name--properties--c/c++ build--builder settings--build commands>> ${ndkroot}/ndk-build.cmd

　　

6. Right click on the project name--properties--c/c++ Build--behaviour

　　

Click Apply--ok when you are finished setting up

7. Right click on the project name--properties--c\c++ General--path and Symbols--includes--gnu C + + Add the following path

• ${ndkroot}/platforms/android-15/arch-arm/usr/include (note the Android version here)
• ${ndkroot}/sources/cxx-stl/gnu-libstdc++/4.6/include
• ${ndkroot}/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a/include
• ${projdirpath}/. /opencv-2.4.10-android-sdk/sdk/native/jni/include (use Projdirpath here to avoid compilation problems caused by using absolute paths, note the OpenCV version here)

　　

After the configuration is finished, click Apply--ok, and the environment deployment is complete.
