Get by property
Get the version number of the firmware through the property name: ro.wp.system.ver. The sample code snippet is as follows:
// returned version such as 1.0.0-3928
String prop = getProperty("ro.wp.system.ver","");
public static String getProperty(String key, String defaultValue) {
String value = defaultValue;
try {
Class<?> c = Class.forName("android.os.SystemProperties");
Method get = c.getMethod("get", String.class, String.class);
value = (String)(get.invoke(c, key, defaultValue ));
} catch (Exception e) {
e.printStackTrace();
}finally {
return value;
}
