android - Creating a product SDK: How do I add a native lib (.so) and a jar with the SDK I am creating?

Question

I am creating a widget that we will provide to developer end users and it consists of a .jar and a native library (.so) built using the NDK. The JAR has a JNI interface to the dynamic library.

It's very clear on how to include an external .jar in a project but not how to include a dependent dynamic library.

1. How do I package up and build the .jar and .so? What are the best practices here?

2. I can create the JAR file using the JDK's jar command. Do I need to run dx.bat on the jar to convert to Dalvik bytecode?

3. I need to create a sample project showing the widget in action. How do I include this .jar and .so in a sample project that demonstrates how to use the widget?

I spent some time on this, and i just can't understand why isn't this written on wikitude documentation.... anyway follow this changes!

• go to windows/preferences/android/build
• uncheck the first and the second option
• extract files from wikitudesdk.jar with winrar as if it is an archive, search libarchitect.so and copy it in /libs/libs/armeabi/
• add wikitudesdk.jar to your build path
