copied!<p>First off, there exists an <a href="http://opencv.org/platforms/android/opencv4android-usage-models.html" rel="noreferrer">OpenCV4Android</a> version of Android, with tutorials on how to use it.</p> <p>Then, as you pointed out, you can code both in Java or C++ on Android. OpenCV4Android can be used in Java [<a href="http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html" rel="noreferrer">1</a>] or in C++ [<a href="http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html#native-c" rel="noreferrer">2</a>]. In your case, it would probably be more convenient to re-use your C++ code, using the <a href="http://developer.android.com/tools/sdk/ndk/index.html" rel="noreferrer">Native Development Kit</a> for Android. If you manage to use the NDK, <strong>you will be able to re-use your C++ code by calling it from your Android app.</strong></p> <p>Here are the few steps I would advise you to follow:</p> <ul> <li>Read about the <a href="http://developer.android.com/tools/sdk/ndk/index.html" rel="noreferrer">Native Development Kit</a></li> <li>Read about the <a href="http://en.wikipedia.org/wiki/JNI" rel="noreferrer">Java Native Interface</a></li> <li>Try to create a sample Android app using C++ (You might find <a href="https://coderwall.com/p/nakhrq?i=1&p=1&q=&t%5B%5D=%21%21mine&t%5B%5D=%21%21bookmarks" rel="noreferrer">this quickstart tutorial</a> useful)</li> <li>Try to integrate OpenCV to your sample [<a href="http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html#native-c" rel="noreferrer">2</a>]</li> <li>Include your existing C++ code in your sample</li> </ul> <p>I hope it will help.</p>
