opencv for android开发

1.基本的设置看http://johnhany.net/2016/01/opencv-3-development-in-android-studio/#opencv-manager

2.注意加入BaseLoaderCallback类，因为不加这个类，调用opencv会出错，原因：

The reason for the error is that Android calls the "onCreate" method before loading the OpenCV4Android library

3.但是在调用onresum中OpencvLoad是会出错，原因：

Android 5.0 service intents must be explicit intents and the OpenCV library uses implicit intents in the
AsyncServiceHelper.java ( new Intent("org.opencv.engine.BIND") ), so it doesn't work.

4.这些问题解决了，就能正常调用了
