Barcode Scanner For Appcelerator Titanium

This is a small barcode scanner module you can use together with Titanium Appcelerator on an Android device.

Build prerequisites

To build the module, there are some dependencies which need to be fulfilled:

Git
Titanium Mobile SDK 1.8.1 or above
Python >= 2.5
Sun Java SDK 6.0
Android SDK with Google APIs and SDK version 4 installed
Ant >= 1.7.1

Build the module

To build the module, you need to clone our git repository and build the sources with ant:

# clone the repository
git clone https://github.com/mwaylabs/titanium-barcode.git
cd titanium-barcode
# run ant to build the module
ant clean && ant

If the build fails, make sure the entries in the buld.properies file point to the right path:

titanium.platform=/Library/Application Support/Titanium/mobilesdk/osx/1.8.1/android
android.platform=/opt/android-sdk/platforms/android-4
google.apis=/opt/android-sdk/add-ons/addon_google_apis_google_inc_4

The newly created *.jar and *.zip files can be found in the dist directory. The module you need is called com.mwaysolutions.barcode-android-$VERSION.zip

Use the module

Build the module or download is from the download section
Place it into your appcelerator project directory
Add the module to the module section of your tiapp.xml file: com.mwaysolutions.barcode
Use it in your application with require('com.mwaysolutions.barcode');
Build your project as usual with the Titanium Developer application

The Scanner looks strange on devices with a high resolution screen?!

If the layout of the scanner activity is not centered, add the following entry to your tiapp.xml:

<android xmlns:android="http://schemas.android.com/apk/res/android">
    <manifest>
      <supports-screens
        android:smallScreens="true"
        android:normalScreens="true"
        android:largeScreens="true"
        android:anyDensity="true" />
    </manifest>
</android>

Code Example

var window = Ti.UI.createWindow({
    backgroundColor:'white'
});

var label = Ti.UI.createLabel();
window.add(label);
window.open();

var titaniumBarcode = require('com.mwaysolutions.barcode');

titaniumBarcode.scan({
  success: function (data) {
    if(data && data.barcode) {
      var label = Titanium.UI.createLabel({
        text:'Barcode: ' + data.barcode,
        textAlign:'center',
        width:'auto'
      });
      win.add(label);
    } else {
      alert(JSON.stringify(data));
    }
  },

  error: function (err) { 
    alert("Error!! " + err); 
  },

  cancel: function () { 
    alert("cancel"); 
  }
});
