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 1.5.0 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/1.5.1/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"); 
  }
});
