Hi! I'm new in WinDev Mobile and I'm trying to create an android application on a honeywell device with a barcode scanner.
I tried 2 different ways and they work on Android studio, but I don't know how to do them on WinDev Mobile.

One version is the following:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import com.honeywell.scanintent.ScanIntent;

public class MainActivity extends Activity {
    TextView barcodeData = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        barcodeData = (TextView) findViewById(R.id.textView);
    }

    public void onSendButtonClick(View v) {
        Intent intentScan = new Intent(ScanIntent.SCAN_ACTION);
        intentScan.addCategory(Intent.CATEGORY_DEFAULT);

        intentScan.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intentScan.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);

        int loadmode = 0;

        intentScan.putExtra("scan_mode", ScanIntent.SCAN_MODE_RESULT_AS_URI);
        this.startActivityForResult(intentScan, 5);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        if (resultCode == ScanIntent.SCAN_RESULT_SUCCESSED) {
            String data = intent
                    .getStringExtra(ScanIntent.EXTRA_RESULT_BARCODE_DATA);
            int format = intent.getIntExtra(
                    ScanIntent.EXTRA_RESULT_BARCODE_FORMAT, 0);
            barcodeData.setText(data);
        }
        else{
            barcodeData.setText("FALLITO");
        }
    }
}


And the other one is this:

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.RemoteException;
import android.view.MotionEvent;

            }
        });
    }
        private void DoScan() throws Exception {

            } catch (RemoteException e) {

        }

On WinDev I created a GLOBAL JAVA PROCEDURE and I generate the application importing the honeywell library, but I don't understand how to implement the android native functions. How can I do this?

Thank you so much!
