The interface file is not needed, and you don't need to create your own interface files.

The swig was used to create the java wrapper that was then included and compiled into the .so file. So look at the sample project to see how to use it.

 

Go to the app/src/main/java directory in the sample project.

There you will find 2 packages.

com.debenu.pdflibrary.* and com.debenu.dqplandroidexample

 

pdflibrary package has 2 files FlatAPIJNI.java which is a jni interface that can call the functions in .so file

the second file is dpl.java which uses the FlatAPIJNI.

 

In your application you have to just import the library package like this:

 

import com.debenu.pdflibrary.DPL;

 

and then you can use the library functions.

Check the dqplandroidexample package, inside it is MainActivity.java file that imports the library package and then uses it.

 

First thing you must do before compilation of the sample project is to search in the MainActivity.java code for this string "...TYPE_YOUR_KEY_HERE..."

You need to replace this string with your library key to unlock it. After that you can use all the functions.

Review the MainActivity.java code for yourself to see how to use the library.
