Android Question Using a Jar Kibrary

[Antonio Contesti Coll]

I've a Jar file called IvrJackU1.jar with some methods
I attach the documentation.

I also have a demo for android and the part of the code that call the method open

reader = new IvrJackService();
// reader = new IvrJackService();
reader.open(this, this);

I can call the method close with no error but i cant call the method open because uses 2 arguments and i dont know how to send in V4A

my code

#AdditionalJar: IvrJackU1

Sub Activity_Create(FirstTime As Boolean)
Dim b As Boolean
Dim aa As Int
b=True
Dim wdj As JavaObject
Dim adp As JavaObject
wdj.InitializeNewInstance("rfid.ivrjacku1.IvrJackService",Null)
adp.InitializeStatic("rfid.ivrjacku1.IvrJackAdapter")
wdj.RunMethod("rfid.ivrjacku1.IvrJackAdapter",Array(GetContext,adp))
aa=wdj.RunMethod ("readEPC",Array(b))
Log(aa)

End Sub

sorry there is one mistake on line
wdj.RunMethod("rfid.ivrjacku1.IvrJackAdapter",Array(GetContext,adp))
is
wdj.RunMethod("open",Array(GetContext,adp)) and doesn't work

Please use [code]code here...[/code] tags when posting code.

Based on the java code you should pass: Array(GetContext, GetContext)

I also tried and i 've the same error
The library tells that open has 2 arguments
arg 0= Context Activity Example
arg 1= adapter used for event interface
Here you have the example of the app in java

public class Demo extends Activity  implements IvrJackAdapter {
 
    private boolean bFirstLoad = true;
    private ImageView imgPlugout = null;
    private TextView txtStatus = null;
    private TextView txtTotal = null;
    private TextView txtDate = null;
    //
    private TextView lblEPC = null;
    private TextView lblTimes = null;
    private Button btnQuery = null;
    //
    private Button btnSetting = null;
    private Button clearScreen;
    private ListView epclist;
    //
    private ProgressDialogEx pd;
    private boolean bSuccess;
    private String cMsg;
 
    private boolean bCancel = false;
    private boolean bOpened = false;
    private MHandler handler = null;
    //
    private CustomListAdapter seqAdapter;
    private ArrayList<seqTag> seqArray = new ArrayList<seqTag>();
    private ArrayList<String> tagArray = new ArrayList<String>();
    private boolean bUpdateRequired = false;
 
    public static IvrJackService reader = null;
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //
        imgPlugout = (ImageView)findViewById(R.id.imgPlugout);
        btnQuery = (Button)findViewById(R.id.btnQuery);
        btnSetting = (Button)findViewById(R.id.btnSetting);
        btnSetting.setVisibility(View.GONE);
        btnSetting.setOnClickListener(new View.OnClickListener()
       {
            public void onClick(View paramView)
            {
                if (bOpened) {
                    showToast("Please stop the inventory tag action.");
                    return;
                }
                Intent intent1 = new Intent();
              intent1.setClass(Demo.this, activity_Setting.class);
              startActivity(intent1);
            }
       });
        lblEPC = (TextView)findViewById(R.id.textView1);
        lblTimes = (TextView)findViewById(R.id.textView11);
        txtTotal = (TextView)findViewById(R.id.txtTotal);
        //
        txtStatus = (TextView)findViewById(R.id.txtStatus);
        txtDate = (TextView)findViewById(R.id.txtDate);
        clearScreen = (Button) findViewById(R.id.btnClear);
        clearScreen.setOnClickListener(new View.OnClickListener()
       {
         public void onClick(View paramView)
         {
           ListClear();
         }
       });
     
        //
        epclist = ((ListView)findViewById(R.id.tag_list));
        epclist.setCacheColorHint(Color.TRANSPARENT);
        epclist.setOnItemClickListener(new epclistItemClick());
       seqAdapter = new CustomListAdapter(this, R.layout.customlistview, this.seqArray);
       epclist.setAdapter(this.seqAdapter);
        //
        btnQuery.setOnClickListener(new btnQuery_Click());
        btnQuery.setVisibility(View.GONE);
        handler = new MHandler(this);
        //
        reader = new IvrJackService();
        reader.open(this, this);

Thanks for the Help

You can use JavaObject.CreateEvent to create the object that implements this interface and handle its callback.
