public class SDCARD123Activity extends Activity implements MediaScannerConnectionClient {
    public String[] allFiles;
    private String SCAN_PATH ;
    private static final String FILE_TYPE="image/*";

    private MediaScannerConnection conn;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {

        //   uriAllFiles= new Uri[allFiles.length];          
        for(int i = 0; i < allFiles.length; i++) {
            Log.d("all file path" + i, allFiles[i]+allFiles.length);
        }
        //  Uri uri= Uri.fromFile(new File(Environment.getExternalStorageDirectory().toString()+"/yourfoldername/"+allFiles[0]));
        SCAN_PATH=Environment.getExternalStorageDirectory().toString()+"/Photo/"+allFiles[0];
        System.out.println(" SCAN_PATH  " +SCAN_PATH);

        Log.d("SCAN PATH", "Scan Path " + SCAN_PATH);
        Button scanBtn = (Button)findViewById(R.id.scanBtn);
        scanBtn.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
                startScan();
            }});
    }

    private void startScan() {
        Log.d("Connected","success"+conn);
        if (conn!=null) {

        Log.d("onMediaScannerConnected","success"+conn);
        conn.scanFile(SCAN_PATH, FILE_TYPE);    
    }

    @Override
    public void onScanCompleted(String path, Uri uri) {
        try {
            Log.d("onScanCompleted", uri + "success" + conn);
            System.out.println("URI " + uri);             
            if (uri != null) {
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(uri);
                startActivity(intent);

How to open default gallery app with particular album or folder?

Try this code. It will retrieve view pictures under storage/emulated/0/Pictures/AppPics You can change the file path according to your directory path.

File sdDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File file = new File(sdDir, "AppPics");

if (file.isDirectory()) 
    listFile = file.listFiles();

EDIT: To open your folder using intent

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.withAppendedPath(Uri.fromFile(file), "/AppPics"), "image/*");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Access Specific folder of gallery in Android

I think it may help somebody...
As i have found solution to my problem.

      private ArrayList<File> m_list = new ArrayList<File>();

      String folderpath = Environment.getExternalStorageDirectory()
            + File.separator + "folder_name/";
         File dir = new File(folderpath);
         m_list.clear();
            if (dir.isDirectory()) {
                File[] files = dir.listFiles();
                for (File file : files) {
                    if (!file.getPath().contains("Not_Found"))
                        m_list.add(file);
                }
             }

m_list contains all the files under folder_name.

Cheers!!

Built-in gallery in specific folder

You just need to implement MediaScannerConnectionClient in your activity and after that you have to give the exact path of one of the file inside that folder name here as SCAN_PATH and it will scan all the files containing in that folder and open it inside built in gallery. So just give the name of you folder and you will get all the files inside including video. If you want to open only images change FILE_TYPE="image/*"

public class sdActivity extends Activity implements MediaScannerConnectionClient{
    public String[] allFiles;
private String SCAN_PATH ;
private static final String FILE_TYPE = "*/*";

private MediaScannerConnection conn;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    File folder = new File("/sdcard/youfoldername/");
    allFiles = folder.list();
 //   uriAllFiles= new Uri[allFiles.length];
    for(int i=0;i<allFiles.length;i++)
    {
        Log.d("all file path"+i, allFiles[i]+allFiles.length);
    }
  //  Uri uri= Uri.fromFile(new File(Environment.getExternalStorageDirectory().toString()+"/yourfoldername/"+allFiles[0]));
    SCAN_PATH=Environment.getExternalStorageDirectory().toString()+"/yourfoldername/"+allFiles[0];
    Log.d("SCAN PATH", "Scan Path " + SCAN_PATH);
    Button scanBtn = (Button)findViewById(R.id.scanBtn);
    scanBtn.setOnClickListener(new OnClickListener(){
    @Override
    public void onClick(View v) {
        startScan();
    }});
    }
    private void startScan()
    {
    Log.d("Connected","success"+conn);
    if(conn!=null)
    {
    conn.disconnect();
    }
    conn = new MediaScannerConnection(this,this);
    conn.connect();
    }
@Override
public void onMediaScannerConnected() {
    Log.d("onMediaScannerConnected","success"+conn);
    conn.scanFile(SCAN_PATH, FILE_TYPE);    
}
@Override
public void onScanCompleted(String path, Uri uri) {
    try {
        Log.d("onScanCompleted",uri + "success"+conn);
        if (uri != null) 
        {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(uri);
        startActivity(intent);
        }
        } finally 
        {
        conn.disconnect();
        conn = null;
        }
       }
}
