public class CameraCapture extends Activity {

                            + File.separator + "myDir" + File.separator);

                    sdImageMainDirectory = new File(root, "myPicName");



                startCameraActivity();

        } catch (Exception e) {
            finish();
            Toast.makeText(this, "Error occured. Please try again …
