View source for How to Detect UU Cable Connnected Programmatically

== Overview: ==
This guide provides instructions and a code snippet for developers on how to programmatically detect the connection of a UU cable. This functionality is essential for applications that need to respond to hardware changes dynamically.
== Implementation Steps: ==
# '''Understand the Context:'''
#* The detection of a UU cable connection is typically handled within the application's code, allowing the app to perform specific actions when the cable is connected or disconnected.
# '''Code Snippet:'''
#* Below is an example snippet that demonstrates how to detect a UU cable connection within your application.
<syntaxhighlight lang="java">
/**
 * Obtain whether the UU cable is connected to the terminal.
 * 1,getSystemService(Context.USB_SERVICE);
 * 2,getDeviceList();
 * 3,finding UU cable features;
 */
