Why do i never enter in specific callback functions in native interface? - codenameone

Question

I'm making an application which has to detect a bluetooth card reader and if a card is inserted or removed from this one.
I'm using an API for the android part in my native interface so I implement two callback functions from an interface which concerns the bluetooth card reader detection and two other callback functions which concerns the detection of cards in the bluetooth card reader.
Two callback functions which are called when the bluetooth card reader is detected and the two others which are called when a card is inserted or removed from the device.
I have no problem with the callback which are called when the bluetooth card reader is detected but the application never calls the functions which must be called when the card are inserted or removed.
public class FtReaderNativeImpl implements BluetoothRead.CardListener,BluetoothRead.ReaderListener{
private BluetoothRead btRead;
ArrayList<BluetoothDevice> listRead;
public String scanBluetooth(){
String chaine ="";
if (Looper.myLooper() == null)
{
Looper.prepare();
}
Log.p("btread avant init:"+btRead);
btRead = new
BluetoothRead(com.codename1.impl.android.AndroidNativeUtil.getContext());
btRead.setCardListener(this);
btRead.setReaderListener(this);
ReturnCode rc = btRead.btInitLib();
Log.p("btread après init:"+btRead);
Log.p("rc:"+rc);
return chaine;
}
#Override
public void CardInserted()
{
//showMessage("onCardInserted");
String chaine="";
//Toast.makeText(com.codename1.impl.android.AndroidNativeUtil.getActivity(), "INSERTED", Toast.LENGTH_SHORT).show();
chaine+=btRead.getName();
chaine+=btRead.getFirstName();
eidReader.showDialog("INSERTED "+chaine);
Log.p("btInsertOK");
}
#Override
public void CardRemoved()
{
String chaine="";
//Toast.makeText(com.codename1.impl.android.AndroidNativeUtil.getActivity(), "REMOVED", Toast.LENGTH_SHORT).show();
EidReader.showDialog("REMOVED "+chaine);
Log.p("btRemoveNOK");
}
#Override
public void ReaderConnected(BluetoothDevice bluetoothDevice)
{
/*Toast.makeText(com.codename1.impl.android.AndroidNativeUtil.getActivity(), "CONNECTED", Toast.LENGTH_SHORT).show();*/
EidReader.showDialog("CONNECTED");
Log.p("onReaderConnected: " + bluetoothDevice.getName());
if (btRead.btOpen(bluetoothDevice) == ReturnCode.OK) {
Log.p("btOpen OK");
} else {
Log.p("btOpen NOK");
}
Log.p("btread après listener:"+btRead);
}
#Override
public void ReaderDisconnected(BluetoothDevice bluetoothDevice)
{
//Toast.makeText(com.codename1.impl.android.AndroidNativeUtil.getActivity(), "DISCONNECTED", Toast.LENGTH_SHORT).show();
EidReader.showDialog("DISCONNECTED");
}}
ScanBluetooth is just a initialization method which is called in the beginning of the form:
public class EidReader extends Form implements HasLogger {
Container loggatt = new Container();
private Bluetooth bt;
private static Container devicesCnt;
private Map devices = new HashMap();
Form main = this;
FtReaderNative frn;
public EidReader(Form parent)
{
this.setLayout(new BoxLayout(BoxLayout.Y_AXIS));
Display dis = Display.getInstance();
frn = (FtReaderNative)NativeLookup.create(FtReaderNative.class);
if(dis.getPlatformName().compareTo("and")==0){
LocationManager lm = LocationManager.getLocationManager();
}
bt = new Bluetooth();
frn.scanBluetooth();
//combo.setRenderer(new GenericListCellRenderer<>(new MultiButton(),new MultiButton()));
this.add(new Button(new Command("enable bluetooth")
{
#Override
public void actionPerformed(ActionEvent evt){
try {
if (!bt.isEnabled()) {
bt.enable();
}
if (!bt.hasPermission()) {
bt.requestPermission();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
}));
this.add(new Button(new Command("initialize")
{
#Override
public void actionPerformed(ActionEvent evt)
{
try {
bt.initialize(true, false, "bluetoothleplugin");
} catch (IOException ex) {
ex.printStackTrace();
}
}
}));
Button bttest = new Button("DISPLAY READER");
bttest.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ev)
{
DeleteUI();
StringTokenizer st = new StringTokenizer(frn.infoDevices());
while (st.hasMoreTokens()) {
MultiButton mb = new MultiButton(st.nextToken());
mb.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ev) {
devicesCnt.add(new SpanLabel(frn.readerStatus( mb.getTextLine1())));
}});
devicesCnt.add(mb);
}
}
});
this.add(bttest);
devicesCnt = new Container(new BoxLayout(BoxLayout.Y_AXIS));
devicesCnt.setScrollableY(true);
this.add(devicesCnt);
this.show();
}
private void DeleteUI()
{
devicesCnt.removeAll();
devicesCnt.revalidate();
}
#Override
public String getLogName()
{
// TODO Auto-generated method stub
return null;
}
public static void showDialog(String txt)
{
//Display.getInstance().callSerially(()->
//{
devicesCnt.add(new SpanLabel(txt));
devicesCnt.forceRevalidate();
//});
}
}
