I've been working on Android (v2.3) for a couple of weeks now, and I've stumbled upon some problems with the Unimag Card Swiper from IDTECH . The unit comes with a scarce documentation and the demo app from the SDK implements the firmware update and a few classes for dialogs and such which really offuscate how to achieve basic functionality (added to the few and not so good comments in the code). I have implemented the interface in a basic activity and tried to detect when the unit is connected or disconnected but it seems the listener catches both events (connection/disconnection) as "disconnect", let alone trying to read a card. Has anyone worked with this unit on Android and has some clear examples? By the way, here is my class: package com.card.swipe; import java.io.File; import java.io.FileOutputStream; import java.io.InputStream; import IDTech.MSR.uniMag.uniMagReader; import IDTech.MSR.uniMag.uniMagReaderMsg; import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.TextView; import android.widget.Toast; public class CardSwipeTestActivity extends Activity implements uniMagReaderMsg { private uniMagReader myUniMagReader = null; private TextView etCardData; private String _strMSRData = null; private byte[]_MSRData = null; private String _strStatus = null; private int _nGetChallengeResult = 0; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // InitializeUI(); InitializeReader(); String strManufacture = myUniMagReader.getInfoManufacture(); String strModel = myUniMagReader.getInfoModel(); String strSDKVerInfo = myUniMagReader.getSDKVersionInfo(); String strOSVerInfo = android.os.Build.VERSION.RELEASE; etCardData =
