How to import JNI to a project

Import .so File

• Compilation: First, compile the latest .so files from the latest API Demo for POS devices.
• Selection and Placement:
  • For standard devices, import and place these files in the lib/armeabi and lib/armeabi-v7a directories.
  • For specific models like WizarPad, place them in the lib/mips directory.
• API Demo Reference: The API Demo includes the following .so files:

Import JNI Interface File

The JNI interfaces generated for smart POS applications can be found in the API Demo. It's important to note a few key guidelines:

• Package Name Consistency: The package name for the JNI interfaces is predefined in the .so file.
  • Important: Do not modify the package name when copying the JNI interface.
  • Example: If the package name is "com.cloudpos.jniinterface," ensure it remains unchanged in your project.

• List of JNI Interface Classes: The API Demo includes the following JNI interface classes:

A visual representation of the JNI interface classes can be helpful. The below image shows the JNI interface classes as found in the API Demo.
