(Android™) SFTP Sync Download Tree w/ Must-Match Filename Constraints

Demonstrates how synchronize a directory tree in the download direction, but only download files matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

import android.app.Activity;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.

    super.onCreate(savedInstanceState);

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

    CkSFtp sftp = new CkSFtp();

    boolean success = sftp.Connect("my-ssh-server.com",22);
    if (success == true) {
        success = sftp.AuthenticatePw("mySshLogin","mySshPassword");
        }

    if (success == true) {

    // Possible synchronization modes are:
    // mode=0: Download all files
    // mode=1: Download all files that do not exist on the local filesystem.
    // mode=2: Download newer or non-existant files.
    // mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server.
    // mode=5: Download only missing files or files with size differences.
    // mode=6: Same as mode 5, but also download newer files.

    // This example will download all files, but only those files having filenames
    // that match *.gif and *.eml

    // Imagine our remote directory tree has these files and directories:

    // 	accentedLatin1.txt
    // 	accentedUtf8.txt
    // 	alice.key
    // 	anter_cert.pem
    // 	chiliPepper.gif
    // 	helloWorld.pdf
    // 	abc/chiliPepper.gif
    // 	abc/ghk/
    // 	data/chiliPepper.gif
    // 	data/xyz/dkimHtmlBody.txt
    // 	data/xyz/dkimVerifyTest.eml
    // 	data/xyz/emailForCreateDsn.eml
    // 	text/frenchUtf8.txt
    // 	text/helloWorld.txt
    // 	text/PolishEmailBody.txt
    // 	text/something/

    // Indicate that we only want to create auto-create local directories (if needed)
    // for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
    // true, then the corresponding local directory is created for each remote directory
    // traversed regardless of whether files within are downloaded.
    sftp.put_SyncCreateAllLocalDirs(false);

    sftp.put_SyncMustMatch("*.eml; *.gif");

    String remoteDir = "syncDownloadTest/someDir";
    String localDir = "qa_output";
    int mode = 0;
    boolean recursive = true;
    success = sftp.SyncTreeDownload(remoteDir,localDir,mode,recursive);
    if (success != true) {
        Log.i(TAG, sftp.lastErrorText());
        return;
        }

    // The following files were downloaded:

    // chiliPepper.gif
    // abc/chiliPepper.gif
    // data/chiliPepper.gif

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
