Add XMP MetaData to JPG or TIFF

See more XMP Examples

Demonstrates how to add XMP metadata to a JPG or TIFF image that doesn't already have XMP metadata. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkXmp xmp = new CkXmp();

    // The first step is to create a new XMP document, which is nothing
    // more than XML.  The NewXmp method returns an XML document with
    // the standard XMP boilerplate.  
    xml = xmp.NewXmp();

    // Add some properties...
    success = xmp.AddSimpleStr(xml,"Iptc4xmpCore:Chilkat","Blah blah");

    // with a text editor:

    if (success != true) {
        Log.i(TAG, xml.lastErrorText());
        return;

    // To add the XMP to the JPG (or TIFF), simply load the JPG,
    // append the XMP, and save:
