Zip Append Files Verbose Logging

See more Zip Examples

An application can check verbose LastErrorText if the zip.AppendFiles method does not append the expected files, or if it appends nothing. 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.

    CkZip zip = new CkZip();

    // Turn on verbose logging to get more informaiton in the LastErrorText property.

    boolean recurse = true;

    success = zip.AppendFiles("*",recurse);

    // Even if AppendFiles is successful, we can examine the LastErrorText property
    // to see what happend.  (This is true for all Chilkat methods.  The LastErrorText always
    // contains information even when the method call is successful.  If you have a difficult
    // time understanding what happened, then turn on VerboseLogging and have a look at it.
    // Make sure to turn off VerboseLogging for production because it could slow down your application.)
