How to Copy IMAP Mail to another IMAP Server

Demonstrates how to copy the entire contents of an IMAP mailbox to another IMAP server. Android™

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

  // Called when the activity is first created.
  @Override

    boolean success = false;

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