Device API
There are three layers of device API, C API, JNI API and Java API. Using any devices of terminal, the application must declare the permission in the manifest file.
- Permissions definition
- WizarPOS printer ESC commands
C API
The C API offers header files definition and the relevant so library is already included in the system. The application developers can create the native so library by the C API to implement their business logic. So the implementation will be more secure than Java implementation. For example, the EMV library can use C API.
JNI API
we offer JNI interface to wrapper the C API to help the developer to use C API. Now we recommended you to use Java API instead of JNI API.
Java API
Java API is packaged as an aar library file, it can be used by Android developer easily. You can download the latest aar library file from below link.
