Listing the modules
Obtaining the list of the connected modules is performed with the
YModule.yFirstModule()
function which returns the first module found. Then, you only need to call the
nextModule()
function of this object to find the following modules, and this as long as the returned value is not
null
. Below a short example listing the connected modules.

public class Inventory extends Activity

}
public void refreshInventory ( View view )
{
LinearLayout layout = ( LinearLayout ) findViewById ( R. id . inventoryList ) ;
layout. removeAllViews () ;
try {
YAPI. UpdateDeviceList () ;
YModule module = YModule. FirstModule () ;
while ( module != null ) {
String line = module. get_serialNumber () + " (" + module. get_productName () +
")" ;
TextView tx = new TextView (this) ;
tx. setText ( line ) ;
tx. setTextSize ( TypedValue. COMPLEX_UNIT_SP , 20 ) ;
layout. addView ( tx ) ;
module = module. nextModule () ;
}
} catch ( YAPI_Exception e ) {
e. printStackTrace () ;
}
}
