IDTech Unimag Card Swiper on Android | Timeout

Question

I'm trying to implement an Android Activity that detects the IDTech card reader accepts a simple card swipe.

Below is the bare bones structure to my implementation for which I took help from here as well

The code:

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import IDTech.MSR.XMLManager.StructConfigParameters;
import IDTech.MSR.uniMag.uniMagReader;
import IDTech.MSR.uniMag.uniMagReaderMsg;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity implements uniMagReaderMsg {

    private uniMagReader myUniMagReader = null;
    private Button btnSwipe;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if(myUniMagReader == null) {
            myUniMagReader = new uniMagReader(this,this);
            myUniMagReader.setSaveLogEnable(false);
            myUniMagReader.setXMLFileNameWithPath(null);
            myUniMagReader.loadingConfigurationXMLFile(true);

            //myUniMagReader.setVerboseLoggingEnable(true);
            myUniMagReader.registerListen();
        }

        btnSwipe = (Button) findViewById(R.id.button1);
        btnSwipe.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                myUniMagReader.startSwipeCard();
            }
        });
    }

    @Override
    public void onDestroy() {
    myUniMagReader.stopSwipeCard();
        myUniMagReader.unregisterListen();
        myUniMagReader.release();
        super.onDestroy();
    }

    @Override
    public boolean getUserGrant(int arg0, String arg1) {
        Log.d("UniMag", "getUserGrant -- " + arg1);
        return true;
    }

    @Override
    public void onReceiveMsgAutoConfigProgress(int arg0) {
        // TODO Auto-generated method stub
        Log.d("UniMag", "onReceiveMsgAutoConfigProgress");
    }

    @Override
    public void onReceiveMsgCardData(byte arg0, byte[] arg1) {
        Log.d("UniMag", "onReceiveMsgCardData");
        Log.d("UniMag", "Successful swipe!");
    }

    final Handler swipeHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            String text = (String)msg.obj;
            TextView dataView = (TextView) findViewById(R.id.text_view);
            dataView.setText(text);
        }
    };

    @Override
    public void onReceiveMsgCommandResult(int arg0, byte[] arg1) {
        Log.d("UniMag", "onReceiveMsgCommandResult");
    }

    @Override
    public void onReceiveMsgConnected() {
        Log.d("UniMag", "onReceiveMsgConnected");
        Log.d("UniMag", "Card reader is connected.");
    }

    @Override
    public void onReceiveMsgDisconnected() {
        Log.d("UniMag", "onReceiveMsgDisconnected");
        if(myUniMagReader.isSwipeCardRunning()) {
            myUniMagReader.stopSwipeCard();
        }
        myUniMagReader.release();

    }

    @Override
    public void onReceiveMsgFailureInfo(int arg0, String arg1) {
        Log.d("UniMag","onReceiveMsgFailureInfo -- " + arg1);
    }

    @Override
    public void onReceiveMsgSDCardDFailed(String arg0) {
        Log.d("UniMag", "onReceiveMsgSDCardDFailed -- " + arg0);
    }

    @Override
    public void onReceiveMsgTimeout(String arg0) {
        Log.d("UniMag", "onReceiveMsgTimeout -- " + arg0);
        Log.d("UniMag","Timed out!");
    }

    @Override
    public void onReceiveMsgToConnect() {
        Log.d("UniMag","Swiper Powered Up");
    }

    @Override
    public void onReceiveMsgToSwipeCard() {
        Log.d("UniMag","onReceiveMsgToSwipeCard");      
    }

    @Override
    public void onReceiveMsgAutoConfigCompleted(StructConfigParameters arg0) {
        Log.d("UniMag", "onReceiveMsgAutoConfigCompleted");
    }
}

The issue here is that I only get these two messages in the Logcat "Swiper is powered up" from onReceiveMsgToConnect()

And After a few seconds (maybe 20 sec)

"Timed out!" from onReceiveMsgTimeout() that sends back a string saying unable to connect to device. I have multiple IDTech devices and this happens the same on every device. Also, sometimes if I am lucky enough I do get: "Card reader is connected." from onReceiveMsgConnected() that means it is connected. But this happens very rarely.

Any help would be very appreciated. Thanks!

Answer 1

Okay so I got it working. I was using an older version of the sdk (unimag.reader.android-1.0.0.jar) and the configuration xml file (idt_unimagcfg_default.xml). I simply updated them to the most recent version of the sdk and the xml.

New versions (as of December 2014) SDK: IDT_UniMagSDKAndroid_v4.4.jar - xml: umcfg.4.4.1.xml

And the timeout problem is solved.

P.S: just as a side note, please also do visit their website for any device specific details you might need for the specific card swiper you are using. For example: I was using a "Shuttle, Two-Track Secure Mobile MagStripe Reader" with a "HTC ONE" phone. After going on to this page here I figured that for HTC ONE I need to turn off my "Beats audio" to appropriately use this device. I hope this helps.
