This example demonstrates how to extract files from a binary SOAP MTOM MIME document. Android™

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

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

    CkMime mime = new CkMime();

    // In this example, we have a MIME file containing 8bit (non-encoded) binary data,
    // and it is what I call "headless".  MIME is headless when it omits
    // the top-level header.  The file we have here begins with the first
    // boundary string.

    // The structure the MIME to be loaded is:

    // multipart/mixed (inferred because it is headless)
    //     application/xop+xml
    //     image/jpeg
    //     image/gif
    //     image/gif
    //
