Open an activity twice but with different values

AndroidManifest:

<activity android:name=".pictureManagement.boundary.DocsIDUI"
        android:configChanges="orientation|screenSize|keyboardHidden"
        android:screenOrientation="portrait"
        android:launchMode="singleTask">

    </activity>

    <activity android:name=".pictureManagement.boundary.PicturePreview"
        android:screenOrientation="portrait"

    </activity>

Activity DocsIDUI:

        if (photoFile != null) {
            imageUri = Uri.fromFile(photoFile);

            Intent intent = new Intent(DocsIDUI.this, PicturePreview.class);

            } else
            {
                bundle.putSerializable(PicturePreview.STEP, 1);
            }
            bundle.putSerializable(PicturePreview.URI_PHOTO, imageUri.toString());
            intent.putExtras(bundle);

When you first open the activity PicturePreview (DocsIDUI -> PicturePreview), it opens normally, but when the return is made and the PicturePreview is opened a second time, when isBackStack is positive, it does not open by going directly
