| This guide provides the necessary steps to obtain the version information for both the firmware and the EMV kernel on your device.
| |
| == Getting the Firmware Version ==
| |
| * Detail the specific method or code snippet required to retrieve the firmware version. This could involve accessing system properties or using specific APIs provided by the device's operating system.
| |
| <syntaxhighlight lang="java">
| |
| public static final String SYSTEM_VERSION = "ro.wp.system.ver";
| |
| public static final String KERNEL_VERSION = "ro.wp.kernel.ver";
| |
| public static final String BOOTLOADER_VERSION = "ro.wp.bootloader.ver";
| |
| | |
| public static String getsystemPropertie(String key, String defaultValue){
| |
| Object propObj = null ;
| |
| try {
| |
| Class<?> systemProperties = Class.forName("android.os.SystemProperties");
| |
| Log.i("systemProperties", systemProperties.toString());
| |
| propObj = systemProperties.getMethod("get", new Class[]{String.class, String.class}).invoke(systemProperties, new Object[]{key,"unknown"});
| |
| Log.i("bootloaderVersion", propObj.getClass().toString());
| |
| }catch (Exception e) {
| |
| e.printStackTrace();
| |
| }
| |
| String prop = propObj.toString().toUpperCase();
| |
| return prop;
| |
| }
| |
| </syntaxhighlight >
| |
| == Getting the EMV Kernel Version ==
| |
| * '''Description:''' This function populates the provided buffer with the EMV kernel version string. The bufferLength parameter specifies the size of the buffer.
| |
| * '''Usage:''' Declare a buffer of appropriate length and call this function to get the EMV kernel version.
| |
| <syntaxhighlight lang="java">
| |
| int emv_get_version_string(unsigned char *buffer, int bufferLength)
| |
| </syntaxhighlight >
