How to import JNI

There are two steps to use JNI interfaces, one is to import so file, the other is to import JNI interface.

Import so file

From latest APIDemo, you can compile the neweast so files of all the devices in the POS. Then select the so file you want to import to your project, put the so file to the path lib/armeabi, and lib/armeabi-v7a(for a special POS, the WizarPAD, the path is lib/mips), .

Import JNI Interface file

From the APIDemo, you can find the JNI interface generated by us, the package name of the JNI interface is defined in the so file, since you can not change the so file, so when copy the JNI interface, please notice that you can not change the package name of the JNI interface.

The JNI Interface class in APIDemo is like the follow picture, "com.cloudpos.jniinterface" is the package name, please don't change that name in your project.
